How can I remove all desktop backgrounds set by users in the domain?

Q: using the Group Policy, user configuration, template management, control panel, and "Hide desktop tabs" or "Block wallpaper changes" displayed, I have implemented that users cannot modify the desktop background. However, many users have already set the desktop background. How can I remove all the patterns with the desktop background already set?

 

 

A:
1. Start/run: Regedit. Open the Registry Editor.
2. Find HKEY_CURRENT_USER \ Control Panel \ Desktop, right-click and export.
3. Name the exported file desktop. Reg and delete useless content. The obtained content is as follows:
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER \ Control Panel \ Desktop]
"Wallpaper" = ""
Note: The empty rows of the 2nd rows must be retained.
4. Create a batch processing file named desktop. bat. Its content is as follows:
Reg import desktop. Reg
5. Specify desktop. BAT as your logon script. The details are as follows:
(1) Start/Program/management tools/Ad users and computers
(2) Right-click the domain/attribute/"Group Policy" label and edit the default domain policy.
(3) user configuration/Windows Settings/script (login/logout)/login
(4) Click "show Files" to copy the previous. Reg and. BAT files to this
(5) Click "add" and "Browse", and specify desktop. BAT as the logon script.
Note:
1. The first time you log on again, the Group Policy is applied. The second time I log on again, the desktop will not have a background.
2. The reg command is available on XP/03, but the reg command is available only after the support tool is installed on the 2000 system. If necessary, you can use suptools. MSI, the installation file in support \ toos under Cd 2000, to distribute the software based on the Group Policy. The Supported tools can be installed on 2000p.

Add description:
You can also use Regedit/s desktop. Reg instead of Reg import, so that you do not have to install the support toos support tool.
