Description and Explanation of a Cabinet File

Cab Files Treated as Folders

XP treats Cab files like folders, to stop this type regsvr32 /u cabview.dll at the command prompt (Start/Run/CMD)
To reverse it type regsvr32 cabview.dll.

Cab Files Install and Relocate

1. Insert your windows XP CD.
2. Click on, Perform Additional Tasks.
3. Click on, Browse this CD.
4. Look for the I386 folder, right click on the folder and copy.
5. Get into, My Computer and create a unique folder.
6. Right click on your new folder and paste.

Then alter the source path: Start/Run/Regedit
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup

In the right pane, double click SourcePath and type in exactly, the path to where the cab files can be found. (The folder to where the cab files have been copied to). Registry, exit.

Caps - Show File and Folder Names Using the Correct Case

Some versions of Windows will attempt to adjust the capitalization of files and folders that are in all uppercase to make them more visually pleasing. For example, if you create a folder named "C:\ALLINCAPS" Windows will actually display it as "C:\Allincaps". This feature can be disabled using this tweak.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Create a new DWORD value, or modify the existing value, called "DontPrettyPath" and set it to equal "1" to display the file using their original capitalization or "0" to adjust the caps.  Restart Windows for the change to take effect.

CD - Backup

HOW TO: Back Up Information to a CD
Recorded CD-ROM Is Missing Files or Folders, or Is Unreadable

Q:  Will XP Pro allow me to back up various files and folders daily be adding only newer or changed files or do I have to
      copy the entire folder each time I back up?
A:  You will need to use packet writing software to format the CD-R/W first. Common packet writing programs are the latest versions of Direct CD (bundled with Easy CD Creator and is not available as a stand alone program but can be install as such www.roxio.com ) InCD (available as a stand a lone program from www.nero.com ) DLA ( comes bundled with the retail version of RecordNow Max or Click n Burn from http://www.stompinc.com/index.phtml?stp  it is available as a stand a
lone product only if you own an HP writer and can be downloaded from the HP site).

XP's native burning software is mastering software. You can not do a one step write to a CD. You must send the file to a caching area and then select the option to Write to CD. You also can not save directly to the CD Writers drive letter. You need to save to the location of the cache. It is found here "C:\Documents and Settings\<log on name>\Local Settings\Application Data\Microsoft\CD Burning" By using the Tweakui for XP Powertoy you can relocate the CD Burning directory to a more readily accessible location. Harry Ohrn MS-MVP [Windows XP]

CD - Files Ready to be Written to the CD (message box keeps appearing)

Default storage is here: Documents and Settings\<username>\Local Settings\Application Data\Microsoft\CD Burning

If you are using TweakUI, go to My Computer/Special Folders see what is set for CD Burning. Make sure it is set to a folder and not a drive.

When the balloon appears: There are two commands to the left of the displayed files. One is Copy to CD and the other is Delete Temporary Files.

If you click Delete Temporary Files, the files listed in the box will disappear. This will not erase the files from your hard drive, it simply removes them from being copied to the CD.

CD-Rom - Incorrect Contents

When you view the contents of a CD-ROM in Windows Explorer, you can see the name of the CD-ROM in the left pane, and the folders are displayed in the right pane. However, after you remove the CD-ROM and insert a different CD-ROM, the right pane may still display the folders from the first CD-ROM even though the left pane correctly displays the name of the new CD-ROM.

To work around this problem, use either of the following methods: Manually refresh Windows Explorer by pressing F5 or by clicking Refresh on the View menu in Windows Explorer. Or do not use Folder view in Windows Explorer.

Incorrect Contents Are Displayed in Windows Explorer

CD-Rom - Listen To CDs Without A Click

Since the advent of Microsoft’s Windows Media Player, playing an audio CD has been a click-free task. However, after installing WinXP, when you insert an audio CD for the first time, the Audio CD dialog box appears. The Play Audio CD Using Windows Media Player is already highlighted, so there’s no need to click it. But before you click OK, click the checkbox next to Always Do The Selected Action. This will restore CD playing to its former click-free glory. Click OK and the CD will play.

NOTE : If you are getting a code 39 message, it may be that additional third-party filter drivers were added to UpperFilters and LowerFilters values in addition to Adaptec filter drivers. In that case, you may try to remove the non-Adaptec filter drivers first, leaving the Easy Creator filters in place to see if the Code 39 goes away. If you still receive an error code 39, 32, or 31 message, remove the Upperfilters and Lowerfilters values completely in the preceding key.

CDR-CDRW

When you attempt to record (burn) data to a compact disc recordable (CD-R) drive or compact disc rewritable (CD-RW) drive, you may not have the option to send data to the CD-ROM drive. To resolve this issue, edit the Windows registry to identify the CD-R drive or CD-RW drive as a recordable drive. To do this, follow these steps.

1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Expand the following registry subkey:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CD Burning\Drives

4. On the File menu, click Export.
5. In the File name box, type backup of drives key, and then click Save .
   
   NOTE: You can restore this registry subkey by double-clicking the backup of drives key.reg file that you saved.
    
6. In the left pane of the Registry Editor window, click the Volume{ GUID } folder under Drives , where GUID is a 32-character hexadecimal globally unique identifier.
   
   NOTE: If you have more than one CD-ROM drive in the computer, an additional Volume{ GUID } folder is listed for each drive.
    
7. In the right pane of the Registry Editor window, double-click Drive Type.
8. In the Value data box, type 1 or 2 , depending on the drive type, and then click OK. The drive type should be 1 if it is a CD-R and 2 if it is a CD-RW.
9. Quit Registry Editor.
10. Click Start , and then click My Computer.
11. Under Devices with Removable Storage , right-click the CD-R drive or CD-RW drive, and then click Properties on the shortcut menu that appears.
12. If the Recording tab is displayed, the drive is successfully recognized by Windows as a recordable device.
13. Click Cancel .
    
    NOTE: If you have more than one CD-ROM drive, DVD-ROM drive, or CD-RW drive in the computer and the Recording tab is not displayed, an incorrect drive may have been configured as "recordable" in the Windows registry. To troubleshoot this issue, follow these steps:
     
    1. Follow steps 1 through 9 to edit the Drive Type value of the Volume{ GUID } folder whose value you previously changed.
    2. In the Value data box, type 3 , and then click OK. The drive type value of 3 indicates that the drive is a standard CD-ROM and is not writable.
    3. In the left pane of the Registry Editor window, click the next Volume{ GUID } folder.
    4. Follow steps 7 through 8 to change the Value data entry to 1 or 2 , depending on the drive type.
    5. Quit Registry Editor, and then follow steps 10 through 12 to confirm that the Recording tab is displayed in the properties dialog box of the CD-R drive or CD-RW drive.

Note that this may not work in all cases. This is only a workaround in a situation where the CD-R drive or CD-RW drive is capable of functioning in Windows XP and for some reason has been misidentified. If the drive is not on the Hardware Compatibility List (HCL), the drive may not work with the built-in CD copying functionality, regardless of this registry setting.

Suggestions and Checkpoints:

Go to Start/Run/CMD and type in: fsutil dirty query c:
(Modify the drive letter accordingly)

If it comes back as dirty, it hasn't cleared. For more information go to Start/Run/CMD and type in: CHKNTFS /?

Option: From a command prompt type chkntfs /D and then reboot, a chkdsk should run but not again on next boot.

After scheduling one or more chkdsks, the entry will contain one or more autochk lines. Delete each of these lines and put the default one in place.

If you always want a check to be performed at startup, change the value to: autocheck autochk /f *

If you don't want any checks to be performed, delete all autocheck entries.

Classic Color Palettes

Choose among Windows XP's color palettes: Right click the desktop, select Properties, click the Appearance tab, and choose a new palette under Color Scheme. At the time of this writing, using Windows XP RC1, the only choices available other than the default blue were olive green and silver.

For a larger selection of palettes, and if you don't mind giving up the "new-and-improved" feel of Windows XP, select Windows Classic under Windows and Buttons. Now click the down arrow under Color Scheme and you'll see lots of choices. Select any one to see what it looks like in the preview area, then click OK to apply it.

Update:  CWS Hijacker disables cleaners.  Workaround by 3bentarrows:

The way to remove the registry key is not obvious. If you just delete it from regedit, since the trojan
DLL is loaded, it will re-add it right back. (Try it. Delete the AppInit_DLLs registry key and hit F5.
Notice that it's added right back by the trojan).

Go to Start/Run/regedit and navigate to this key:

1. Rename the HKLM\Software\Microsoft\Windows NT\CurrentVersion\Windows folder to Windows2.
2. Now delete the AppInit_DLLs key under the Windows2 folder.
3. Hit F5 and notice that AppInit_DLLs doesn't come back.
4. Rename the Windows2 folder back to Windows.

Now that AppInit_DLLs is gone, run the latest Adaware 6 to remove the trojan for good. Reboot your machine.
Check the registry and make sure AppInit_DLLs is still gone. Your computer should be free of this for good now.

Common Dialog - History

By default, Windows Explorer-style dialog boxes (for example, the Open dialog box and the Save As dialog box) provide both a most-recently-used (MRU) list of file names and an AutoComplete list of previously typed file names.

To prevent the MRU list and the AutoComplete list of file names from appearing, use the procedures that are described in this section.

How to Prevent the MRU List of File Names from Appearing

NOTE : After you complete this procedure, the MRU list does not appear in Windows Explorer-style dialog boxes; however, this list is not removed from the registry.

Windows XP Professional:  Log on as the user. Click Start, and then click Run. Type gpedit.msc, and then click OK.

In the left pane under User Configuration, expand Administrative Templates, expand Windows Components, expand Windows Explorer, and then click Common Open File Dialog. In the right pane, double-click Hide the dropdown list of recent files. Click Enabled, and then click OK. Click File, and then click Exit.

Windows XP Home Edition: Log on as the user. Click Start, and then click Run. Type regedit, and then click OK .
Locate and then click the following key in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Comdlg32

NOTE : If the Comdlg32 key does not exist, follow these steps: Click the Policies key. On the Edit menu, point to New, and then click Key. Type comdlg32, and then press ENTER. On the Edit menu, point to New, and then click DWORD Value.
Type nofilemru, and then press ENTER. On the Edit menu, click Modify. Type 1, and then click OK. On the File menu, click Exit.

How to Prevent the AutoComplete List of File Names from Appearing
 
To prevent the AutoComplete list from appearing in typical Windows Explorer-style dialog boxes, turn off the AutoComplete functionality for Windows and Microsoft Internet Explorer: Start Internet Explorer, click Tools, and then click Internet Options. Click the Content tab, and then click AutoComplete. Under Use AutoComplete for, click to clear the Web Addresses check box, and then click OK. Click the Advanced tab, click to clear the Use inline AutoComplete check box in the Browsing section (if this check box has been selected). Click OK.

Common Groups - Hide

In the Start Menu, groups (subfolders) in the upper part of the Programs menu are specific to each user, while groups (subfolders) in the lower part are common to all users. In order to prevent a user from viewing the common groups, make the following Registry change:

Containing Text - Search Issue

Windows® XP has a known issue for not finding a number of File Types when you do a Search for Files "containing text" or using the "A word or phrase in the file" option. This can be remedied for many file types, but not all. The cause is the lack of a PersistentHandler value in the Registry for this type of file.  Fix:  http://www.dougknox.com/xp/tips/xp_bad_search.htm

Using the "A Word or Phrase in the File" Search Criterion May Not Work

Content Advisor

Remove the Content Advisor and Ratings Password

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Ratings

Open your registry, find the key below. Single click on the key to highlight it, press the DELETE key, or alternatively select Delete from the Edit menu. Close Internet Explorer, re-open it, and the Content Advisor feature should be disabled.

Content Advisor - Apply per user

Content Advisor On (vb script).  Download it (you may want to right click and use Save Target As) and save it to your desktop.  Then place it in the startup folder of each account you want it activated in. 

Next, download the Content Advisor Off (vb script) and place it in each startup folder that you don't want/need it activated in.

Both scripts can be found here:  (scroll to the very bottom)
http://www.kellys-korner-xp.com/xp_tweaks.htm

Content Advisor Restrictions

These settings allow you to control the Content Advisor feature of Internet Explorer. Including the option to disable Content Advisor, require a supervisor password and view unrated content.

Open your registry (Start/Run/Regedit) and find the key below, create it if it does not already exist.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Ratings\.Default]

Value Name: Allow_Unknowns, Enabled, PleaseMom
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = disable, 1 = enable restriction)

Create a new DWORD value for each required restriction from the list below.

• Enabled - (1 = enable content advisor, 0 = disable)
• Allow_Unknowns - (1 = display unrated sites, 0 = restrict unrated sites)
• PleaseMom - (1 = allow supervisor password, 0 = no supervisor override)

Restart Internet Explorer for the changes to take effect.

Context Menu - Customizing Windows Explorer Context menu (right click menu in windows explorer)

Ever wondered how does the right click menu (which is actually a context menu) work? For example, when I right click in windows explorer, I see an option which says "open command window here". This is seen because you have following entries in the registry.

[HKEY_CLASSES_ROOT\Drive\shell\cmd]
@="Open Command Window Here"

[HKEY_CLASSES_ROOT\Drive\shell\cmd\command]
@="C:\WINDOWS\System32\cmd.exe /k cd "%1""

If You have never used a tweaking utility and have newly installed Windows XP, You would not see this option. You would have to navigate to [[HKEY_CLASSES_ROOT\Drive] go and create two subkeys ("cmd" and within that "command" and would have to put the text "Open Command Window Here" without quotes in default string value of "cmd" key and the text "C:\WINDOWS\System32\cmd.exe /k CD"%1"" without quotes in default string value of command key). After this You need to REBOOT for these changes to take effect.

Context Menus (Right Click) - Deleting entries

Click Start, Run and enter REGEDIT Go to:

HKEY_CLASSES_ROOT\*\OpenWithList
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Directory\shell
HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shell
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Folder\shell
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

You can also go to a specific File extension (example: HKEY_CLASSES_ROOT\.txt\ShellNew) and right click on the ShellNew key and select Delete, if the item shows up in the New context menu.

Expand the above branch and look through the sub-keys. Locate the one that corresponds to the entry you wish to remove and right click that sub-key and select Edit.

You may wish to right click the desired sub-key and select Export. This will create a REG file that you can double click to re-import the information, if you find out you deleted the wrong one, or want it back.

Customizing Right-Click Menu Options in Windows

Right Click - Submenus

The new OpenExpert is the answer to this problem! Instead of messing around with a fixed association of a file type with only one application, it adds an "Open with" item to the context menu of the chosen file type with all the applications you decide.

Control-Alt-Delete - Enable

To Enable or Disable the CTRL+ALT+DELETE Sequence

1. Click Start, click Control Panel, and then click User Accounts.
2. Click the Advanced tab.
3. In the "Secure logon" section, select or clear the "Require users to press Ctrl+Alt+Delete" check box.

If you want to set up a requirement for a user to press CTRL+ALT+DEL before the classic logon is displayed, in the same manner as it behaves on Windows XP Server:

1. Click Start/Run/Regedit, and then click OK.
2. Select the Winlogon subkey at the following registry location:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

3. Click Edit, click New, and then click "DWORD value".
4. Change the value name to "DisableCAD" (without the quotes) and press ENTER.
5. Keep the data value set to 0 which is displayed as 0x00000000(0).

If the Welcome screen is enabled, the computer can be locked if you press CTRL+ALT+DELETE (to open Task Manager), and then click Lock Computer or click Switch User on the Shut Down menu. 

Control, Alt, Delete Process Explained and Key Commands

Control-Alt-Delete - Use Crtl + Alt + Delete to Restart the Computer

Normally when you press Ctrl + Alt + Delete the Windows task list is displayed. Using this tweak the key combination will instead reboot the computer. Open the SYSTEM.INI file found in the Windows directory using Notepad.

Under the [386Enh] section create or modify the value named "KybdReboot". Set the value to equal "True" to cause the system to reboot on the key combination or "False" to show the task list. For example:

[386Enh]
KybdReboot=False

Restart Windows for the change to take effect.

Control, Alt, Delete Process Explained and Key Commands

Control Panel Applets

This tweak does not prevent the control panel applets from running, they just do not show up in control panel any more.

Start/Run/gpedit.msc. User Configuration/Administrative Templates Folder/Control Panel Folder. Select Show only specified Control Panel Applets (right pane) properties. Select the enable button/click the Show button.

A new window will pop up that will display control panel objects that are OK to show. Items not on this list will not be displayed in control panel when this feature is enabled. Here are the Windows XP Pro Control Panel applets:

System Properties = sysdm.cpl
Network Connections = ncpa.cpl
ODBC Administrator = odbccp32.cpl
Display Properties = desk.cpl
Add or remove programs = appwiz.cpl
Internet Properties = Inetcpl.cpl
Game Controllers = joy.cpl
Phone and modem Options = telephon.cpl
Time and Date Properties = timedate.cpl
Region and Language Options = intl.cpl
Power Options = powercfg.cpl
Mouse Properties = main.cpl
Accessibility Options = access.cpl
Add Hardware Wizard = hdwwiz.cpl
Sound and Audio Devices = mmsys.cpl
User Accounts = nusrmgr.cpl
Speech Properties = sapi.cpl

Control Panel - Classic

You can remove the "common tasks" pane from the left side of your open folder windows: inside a folder window, click the Folder Options icon, select Use Windows Classic Folders, then click OK. Similarly, you can switch from the new, task-oriented Control Panel (great for new users or those who want to perform common tasks without wading through dialog boxes) back to the "classic" version. Open the Control Panel (select Start, Control Panel), and in the common tasks pane on the left side of the window, click Switch to Classic View.

Control Panel - Display

This setting specifies the visual style of the Control Panel. Allowing you to either force the use of the new XP style, classic style or allow the user to select the preferred style. Go to Start/Run/Regedit and navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Create a new DWORD value, or modify the existing value, called 'ForceClassicControlPanel' and edit the value according to the settings (0 = force new, 1 = force classic).  Exit your registry, you may need to restart or log out of Windows for the change to take effect.

Control Panel - Icons Missing

Click Start, Run and enter REGEDIT

Go to: HKEY_CURRENT_USER\Control Panel\don't load

Look in the right pane and you'll see the Control Panel Icons that have been disabled. You can either right click on the "don't load" subkey and select Delete to restore all disabled icons, or you can right click on each of the items in the right pane and select Delete to selectively restore them. Scroll up to Control Panel Applets for a listing of what each one is.

The change will be seen the next time you open Control Panel.

Control Panel - Tools (Reference)

Have You noticed the new view of control panel in XP. Well as its says, its a view and you can switch to a classic view anytime. But if you like the view but want to customize the categories, there is again a good article on How to do this :
How to Add a Control Panel Tool to a Category (Q292463).

You can get complete details by visiting the site but in brief a control Panel tool can be included in a particular category by adding a registry DWORD entry for the tool in the following registry key:  Go to Start/Run/Regedit:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Control Panel\Extended Properties\{305CA226-D286-468e-B848-2B2E8E697B74} 2.  Value category ids are:

0x00000000 : Other Control Panel Options (any tool that does not specify a category ID is placed in this category)
0x00000001 : Appearance and Themes
0x00000002 : Printers and Other Hardware
0x00000003 : Network and Internet Connections
0x00000004 : Sounds, Speech, and Audio Devices
0x00000005 : Performance and Maintenance
0x00000006 : Date, Time, Language, and Regional Options
0x00000007 : Accessibility Options
