Access Denied:  Error Message - Windows Update

Network policy settings prevent you from using Windows Update to download and install updates on your computer. If you believe you have received this message in error, please check with your system administrator.

     For Windows XP Pro:

Start/Run/gpedit.msc. User Configuration/Administrative Templates/Windows Components/Windows Update. In the right pane, double click, Remove access to all Windows Update Features and set it to disabled.

     For Windows XP Home Edition:



Locate the value in the right pane called DisableWindowsUpdateAccess. Double click this entry and change the value to 0 (zero) or right click it and select Delete.

If editing the Registry manually isn't to your liking click here for a small Visual Basic Script that will make the change for you.

Windows XP Prompts You to Re-activate After You Restore Your Computer

Activation - Explained: 

Windows XP will typically remind you to activate the product (most users will have 30 days to activate XP after installation).

To activate XP manually, you can use the Start menu shortcut in the System Tools Accessories folder. At the command prompt, type:  oobe/msoobe /a or Start/All Programs/Accessories/System Tools/Activate Windows.

     Tip:  msoobe stands for "Microsoft Out of Box Experience."
     Tip:  Windows Product Activation  by MS-MVP Alex Nichol

Activation - Workaround (Ronnie Vernon MVP)

If you are doing a repair reinstall of XP on the same hardware, you can back up the activation status and then restore it after you run the repair install of the OS. To save the activation status, back up the wpa.dbl file from the %systemroot%system32 folder to a floppy disk.

After the repair install of the OS is complete, start in Minimal Safe mode. Open the %systemroot%system32 folder.  Rename wpa.dbl to wpa.noact. Copy the backed up wpa.dbl file to the system32 folder. Reboot your system.

This isn't a hack to avoid activating installations and will work only on the same hardware for an XP installation that you've already activated.

Add and Remove

Hide selective programs/applications listed in Add or Remove:

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

Local the program in question in the left pane. In the right pane, right click DisplayName and select rename:  Add Quiet so it will read:
QuietDisplayName.  No reboot or refresh needed. Open Add or Remove - the listing is now gone.  To revert, rename back to DisplayName.

Add Programs to Add/Remove

To add additional components to the Add/Remove Programs list (Windows Components):

Tools/Folder Options/View/Show Hidden Files and Folders and Show Extensions for known file types. Then go to Windows Explorer/Inf Folder/Sysoc.inf (Double Click it). You will find several lines that include the word 'hide'. Simply remove the word 'hide' (but leave the comma). Save and exit. From there you will be able to remove it from add/remove.

Add and Remove -  Show All Files

Windows XP doesn't let you add or remove all the programs it installs by default. Multimedia applications, the XP messenger, games, accessories, and accessibility options do not show up in the Add/Remove Programs dialog box. What if you want to get rid of them? Here's how to make Windows treat these applications just like it treats all the others.

Go to Windows Explorer/Inf. In the right pane, scroll down to sysoc.inf, double click it. Scroll down to: 

IndexSrv_System = setupqry.dll,IndexSrv,setupqry.inf,,7
TerminalServer=TsOc.dll, HydraOc, TsOc.inf,hide,2


  1. The word "HIDE" in an entry hides that application from your Add/Remove Programs dialog box. To add games to the Add/Remove menu, delete the word HIDE from its entry (but leave the commas that surround it). You also have to remove "HIDE" from "AccessUtil=" for this tip to work.  

  2. Save the file. Check for the new entries in the Add/Remove Programs dialog box after you restart your computer.

Add and Remove -Removing Invalid Entries in the Add/Remove Programs Tool



Each program listed in Add/Remove Programs has a subkey listed here. Locate the correct subkey for the program in question and right click it, then select Delete.  You may want to choose Export, first, to export the key to a REG file.  The REG file can be re-imported if you find you made a mistake.

You may have to contact the manufacturer of the program that you want to remove if you need to clean up the disk and registry entries. The procedure described in this section does not remove all the files and registry entries used by the program; it removes only the reference in the Add/Remove Programs tool.

Note:  Other checkpoints to consider when trying to remove a program:

Check to see if the software/program is listed here: Start/Run/Regedit


1. Right click the Program's shortcut/Properties to gain the Target Path.

2. Go to Start/Run/Msconfig/Startup and make sure it is not listed or checked there. If so, uncheck it and remove the program listing from here: Start/Run/Regedit

For items that were in the Start menu, Programs, Startup folder:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftShared ToolsMSConfigstartupfolder. You'll find a subkey for each disabled item.

For items loaded from the Registry:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftShared ToolsMSConfigstartupreg. Again, you'll find a subkey for each disabled item.

Clear Disabled Items from Msconfig Startup (Line 148)

3. Go to Windows Explorer/Tools/Folder Options/File Types. If the program file type is listed, either use Change or Delete.

4. Go to Start/Run/Regedit and navigate to this key: HKEY_CLASSES_ROOTApplications. If the program is listed, right click, delete.

5. Go to Start/Run/Regedit and navigate to these keys:
HKEY_CURRENT_USERSoftware and HKEY_LOCAL_MACHINESOFTWARE. If the program is listed, right click, delete.

6. Go to Start/Run/Regedit. Edit/Find and under Find What type in the program path gained from step one. From there either use Find next or F3.

Add and Remove vs. System Restore
- Anshul Rawat [MS]

System Restore does not completely uninstall any program by itself if restoring to a point prior to the program installation. Since system restore is based on an inclusionary model, any file added or modified by the installation which System Restore does not monitor or files added to or modified in a non monitored drive will not be tracked by System Restore.

Thus System Restore cannot delete or undo any modifications made to these files. To remove all the changes an installation may have made on the system, the user should first use the Add/Remove option in the control panel to remove the application prior to using System Restore. System Restore however will undo all recorded changes made to the registry & monitored
files caused by the application install including:

  a.. Delete monitored  files the program installation may have added to the system
  b.. Undo modifications to monitored  files made by the installation
  c.. Replace the current registry with the registry snapshot taken when the restore point chosen was created. (*note: some
       current values will persist)
  d.. Any file type not monitored by System Restore added or modified on the system will not be restored or removed. E.g.
      .jpg, .txt files.

Device Manager Conflicts, Error Codes and Solutions

Add New Hardware Error Message:  "Found New Hardware Wizard" advises, "Cannot install this Hardware. There was a problem installing this hardware: PCI Simple Communications Controller. The data is Invalid.

This is caused in XP by the new PCI Registry entry defaulting to "Read" under Permissions. Also, the Device Manager shows the typical yellow query against other Devices/PCI Simple Communications Controller.

Suggested Solution/Fix:

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

Open each sub-key: Ven_XXXX... In the right pane read the Value Data for each DEVICEDESC, until you find your modem. Once found, right click the 3&71aaa sub-key and select Permissions and under the word "Allow", select "Full Control", click OK then go to File/Exit.

Then go to the Device Manager, right click on the device name that matches the "DEVICEDESC" value you changed in the registry. Select Properties/Driver/Update Driver. Windows will now ask you for the disk or CD-ROM that contains the driver for the failing device.

This error can also occur when configuring drivers for a such as SCSI cards, Network cards, Sound Cards, or other peripherals.  This symptom appears to occur when there has been a recent hardware configuration change within Windows XP.  This error is believed to be due to an issue occurring when hardware enumeration takes place by the operating system.

Right-click the Start button, and then click Properties. On the Start Menu tab, click Customize. On the Advanced tab, under Start menu items, click System Administrative Tools. Click to select either the Display on the All Programs menu or the Display on the All Programs menu and the Start menu option. Click OK , and OK again to save the change.

     Tip:  Administrator Tools Missing: Open a Search window and do a find for *.msc files in C:WindowsSystem32. You
              can create the missing shortcuts by pointing them to the correct file.

Administrative Tools on the Start Menu - Hide

This folder contains powerful administration utilities and therefore can be hidden to avoid accidental use.

Open your registry (Start/Run/Regedit) and find the key mentioned below.


Value Name: StartMenuAdminTools
Data Type: REG_SZ (String Value)
Value Data: Yes or No

Create a new string value, or modify the existing value, named 'StartMenuAdminTools'. Modify the value to equal 'YES' to show the administrative tools folder or 'NO' to hide it. Exit your registry and log off for the changes to take effect.

Note: By using the same key except under the [HKEY_LOCAL_MACHINE] tree the tweak can be enforced system wide, instead of only user based.

Note: Hiding the folder does not stop the use of the tools, it only make it more difficult to locate them.
