Defragmentation - Disk

Defrag - Run as a Scheduled Task:

A small VB Script can be used to run DEFRAG as a Scheduled Task.  This script will scan your system and identify all hard disks, then will execute the DEFRAG program for each one.  Create a new Scheduled Task and point it to this VBS file.  The task must run with Administrator credentials.   The script can be downloaded here.

To only defragment one drive as a Scheduled Task, go to Start/Programs/Accessories/System Tools/Scheduled Tasks/Add Scheduled Task.

Enter DEFRAG.EXE X: -F where X is the drive you wish to defragment.

The only way a non-administrator can defragment a local volume is to run the Dfrg.msc console in the context of a user who has administrator privileges. You can accomplish this by running the following command:

Right click and select runas / "mmc dfrg.msc".  The user is prompted for the administrator password. This command may be useful for an administrator who wants to run a defragmentation on a user's computer without forcing the user to log off.

Defrag on Boot - Enable/Disable

A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option is enabled but on some builds it is not so below is how to turn it on.


Select Enable from the list on the right. Right on it and select Modify. Change the value to Y to enable and N to disable.
Reboot your computer.

Also see HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters and EnablePrefetcher = 1 application launch prefetching, 2 boot prefetching
add the numbers.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\ "Enable"="Y" (Y = defrag will optimize for boot and app launch)

More detailed info by MVP Jimmy S.:

To download and install a DRIVER for your video card.

XP users should create a restore point before any upgrades:

If your video card meets the game requirements, but
Dxdiag.exe is still reporting N/A, you must reinstall
DirectX and update your video card drivers. If the issue
continues after you reinstall DirectX and you update your
video card drivers, this may be a Microsoft Windows
problem. Contact Windows technical support to continue
troubleshooting this issue.

Updating video card drivers can solve most gaming issues. Here's some
simple abc's to always keep in mind.

a. Shut off download accelerators, firewalls and antivirus programs when
downloading or installing updates;
b. Check for game patches:
c. Make sure you meet the game's minimum video and system requirements.

Along with your Video card, Sound Cards, Motherboard Chipsets,
and Video Monitors may also require updated drivers. Even your
motherboard's BIOS may need to be updated for compatibility with
your Video card.

Before you update your drivers, I recommend that you install DirectX 9.0b:

Here are the steps I recommend you use to update your driver:

1. To identify the make and model of your card, right click your
Desktop, choose Properties / Settings / Advanced / Adapter.

2. Download the latest video driver for your card online, using
to find the website to download from. I also have advanced
video driver and direct X troubleshooting steps on that page.

3. Save the .exe driver (or extract the zip file) to a folder
in My Documents named after the driver version number.

4. Restart the computer in Safe Mode by pressing the F8 key
about once every second as it's rebooting to pick Safe Mode.

5. Click Start / (settings) Control Panel / System / Hardware
Device Manager / expand +Display Adapters / right click on
the adapter, pick "Uninstall", and click No if asked to reboot.

6. Use Control Panel / Add-Remove programs to uninstall the
previous driver (exe) software which may have been installed.

7. Restart the computer in Safe Mode by pressing the F8 key
about once every second as it's rebooting to pick Safe Mode.

8. If the driver is NOT a (.exe) program file, GO TO step 11.

9. When Windows prompts you to install the video adapter, click
"Cancel" and Double click the driver program to begin installation.
*Even if not prompted, double click the driver and install it.

10. After you reboot, go to Control Panel / Display / Settings and
choose 32 bit Color Quality, and 800x600 or higher Resolution.
That's it! Scroll down to the Troubleshooter if you have problems.

11. When Windows prompts you to install the video adapter, click
"Install from a list or specific location", click the "Browse" button,
browse to the My documents folder where you saved the driver,
and finally click on one of the driver files to begin installation.

** If you are not prompted, or if the driver was updated automatically:
Click Start / (settings) Control Panel / System / Hardware Device Manager
expand +Display Adapters / right click on the adapter, pick "Update

To start the Update Wizard, choose the "Install from a list..." option:
Browse to My Documents\ folder with the driver in it
Click OK and click Next to begin the update.

12. After you reboot, go to Control Panel / Display / Settings and
choose 32 bit Color Quality, and 800x600 or higher Resolution.
That's it! Try the advice in the Troubleshooter if you have problems.


Test your drivers using DXDiag: Click Start / Run / type: DXDIAG
Click the "Test" buttons in the Display, Sound, Music & Network Tabs.

If any of the Display options are Disabled and you cannot Enable them,
your most likely solution would be to update your Chipset Drivers as per
my website:

Your program might not support dual monitors, or "dual head" video cards
You can disable the extra video output in your display properties control
panel. Click Start>Settings>Control Panel>Display>Settings>Advanced.

Perhaps the old Video drivers did not completely uninstall. If that's the
case, use these utility to completely uninstall the drivers and go to step 7:

or for all cards including nvidia use:

The latest video drivers sometime don't work with a particular game.
(Check the Video suggestions in the readme.txt file in your game folder/CD).

If there's no suggestions, try an older (WHQL) driver, and/or if you still
experience problems try a Beta driver, or even an Omega driver instead:

DLL File Downloads

If your Windows applications and programs are missing the correct dynamic link library files ( otherwise known as DLL files or .dll ) you've probably been faced with either a reinstallation of your software or a non working application. This DLL download page contains links to the most commonly needed DLL files, most are in zip file format. Using WinZip or similar, most users will simply have to unzip the DLL file they are missing into their default C:/Windows/System directory to restore program functions.   Downloads can be obtained from here:

DLL's - Make DLLs Display Their Icons in Windows Explorer

By default Windows Explorer displays a generic icon for all DLL files even if some of them contain icons. If you sometimes look inside those DLL files at their icons you know that many DLLs have no icons, and some do. If you'd like to know at a glance which ones have icons then a quick Registry edit is just what you need. This tweak will change the default so that the first icon contained in a DLL is displayed in Windows Explorer.

Start/Run/Regedit: HKEY_CLASSES_ROOT\dllfile\DefaultIcon. First back up the key you are about to modify:
Highlight (Default) in the right frame and select Export Registry File... from the Registry pull down menu. Export or save the file to the location of your choice.

If you don't like the results of this tweak, simply double click the exported file to undo the changes you are about to make.
Right click (Default) and choose Modify.

Replace all the information contained in the Value data: field with %1. Exit Regedit, reboot and launch Windows Explorer. Find a file called Shell.DLL in C:\Windows\System and note that it, and many other DLLs now display an icon.

DLL's - Unload



Create a new sub-key named 'AlwaysUnloadDLL' and set the default value to equal '1' to disable Windows caching the DLL in memory. Restart Windows for the change to take effect.

How to Use Dumpchk.exe to Check a Memory Dump File

Dumprep - Explained (Microsoft)

It has various mode of functionality. ER Utility Application - This will be referred to as dumprep.exe from here forward.

This application houses a few simple functions to be used when a separate application is needed to perform certain tasks (such as snapping a minidump of a process, etc).

Queued reporting:

This goal of this mode is similar to that of regular manifest exception reporting: prevent non-privileged users from accessing data they should not be accessing. In regular manifest mode, we have the possibility that a non-privileged user could see a minidump from a service process if he was logged onto the local console when the service faulted.

Even if he does not look at the minidump, he is potentially given the option of reporting the fault to Microsoft- which may not be what a machine admin would want to do.

To work around this, we introduce the concept of queue. Queue works very similarly to kernel fault reporting.

1. We enter queue at the point which we left manifest exception reporting above. Note that we never return to manifest exception reporting mode. When we finish, we go directly back to the point where we left 'user mode exception' reporting.

2. The ERSvc invokes faultrep.dll to do the actual reporting. Faultrep.dll is loaded into the ERSvc process.

3. A user fault signature is extracted from the minidump.

4. The fault is stored in the user fault queue directory. If the directory is located on an NTFS drive, we attempt to use NTFS
compression to compress the file.

5. The fault signature as well as some other metadata about the fault is packaged into a structure and stored in the registry along with the pointer to the file in the queue directory. We also dumprep.exe to the HKLM 'Run' key, which causes dumprep.exe to get executed every time a user logs in (until it is removed from the 'Run' key).

6. We check and see if the fault reporting queue is above the maximum number of entries (10 by default) and delete the oldest entry from the queue.

7. Wait for an administrator to log in interactively (either at the local console or via terminal server / remote desktop). Note that we really return back to the faulting app here and do not actually cause the faulting app to 'wait'. However, the fault reporting process for this fault effectively waits.

8. When an administrator logs in, dumprep.exe runs and checks the list of user faults. If it is empty, dumprep.exe (and ER) terminates.

9. We attempt to acquire a global mutex that only administrators have access to (this is how we enforce administrator access to reporting). If we fail, dumprep.exe (and ER) terminates.

10. We read an entry from the registry list. That the following steps occur once for each entry in the list.

11. Faultrep.dll is loaded and called with the path to the minidump to report & the user fault metadata we stored away in the registry.

12. Faultrep.dll is loaded and the registry based configuration is checked.

a. If both reporting and notification are disabled, ER terminates.

b. If reporting is enabled and notification is not, we report in silent mode

c. If notification is enabled and reporting is not, we display a pop up notifying the user of the fault, but there is no 'Send / Don't Send' button set. There is just an 'Ok' button.

d. If both are enabled, we report normally.

13. We collect application compatibility data if possible and store it in a file in the temp directory.

14. The DW manifest is constructed.

15. DW is launched. The behavior is described in the 'DW Process' section above.

16. Once DW returns, ER terminates (or repeats if we have been called by dumprep.exe and there are additional faults to report- note, if the DW dialog remained up for more than 5 minutes without user interaction, then no further reports will be offered to the user. The next admin who logs in will be offered the opportunity to report).

HKEY_CURRENT_USER\ RemoteAccess\ Profile
HKEY_CURRENT_USER\ RemoteAccess\ Addresses

Select Export Registry File from the File menu, and save this branch in another file on your hard disk - this file will contain entries for all of connections, so if you have more than one connection here, you must edit the second Registry file manually with a text editor and remove the unwanted entries.

At this point, you can merge the two registry files (using a text editor, such as Notepad, and making sure the word "REGEDIT4" appears only once).

When you're finished, you should have a single Registry file (*.REG), on which a user can simply double-click to add the connection to their system.
