Frequently Asked Questions

How to deploy wufuc using Group Policy

There is a tutorial on the Advanced Installer website that explains how to do this.

How to use unattended feature in the batch setup scripts

install_wufuc.bat and uninstall_wufuc.bat both support two command line parameters that can be used alone, or combined to change the behavior of the scripts:

  • /NORESTART - Automatically declines rebooting after the setup finishes.
  • /UNATTENDED - Skips all prompts for user interaction, and automatically restarts unless /NORESTART is also specified.

These must be used from an elevated command line prompt.

How to restore Windows Update to its default configuration

Windows Update by default is configured to run as SERVICE_WIN32_SHARE_PROCESS, which means it shares a single svchost.exe process with several other Windows services. It can also be configured as SERVICE_WIN32_OWN_PROCESS, which means it runs in its own process, which doesn't start until Windows Update does.

Normally, either of these configurations is supported.

However, if you have used another third-party solution for the CPU fix (such as UpdatePack7R2 or WuaCpuFix) either knowingly or unknowingly, wufuc will not function correctly if Windows Update is configured as SERVICE_WIN32_OWN_PROCESS.

You have two ways to work around this limitation, either:

  • You can remove the other third-party solution yourself.
  • Alternatively, go to the directory that you installed wufuc to, open the Troubleshooting subdirectory, and merge the Restore_wuauserv.reg file with your registry by double-clicking it, and then restart your PC.

How to manually remove wufuc v0.8.0.143 when it is impossible to uninstall it normally

This applies exclusively to a very buggy version of wufuc that was only available for download for a short period of time, other versions are unaffected.

  1. Boot into Safe Mode with Command Prompt.
  2. In the command prompt type regedit and press enter.
  3. Navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
  4. Expand the Image File Execution Options tree.
  5. Locate the svchost.exe sub key, right-click it and press Delete.
  6. Reboot, and you should be able to log in normally again.
  7. Open Add and Remove Programs, locate and run the normal wufuc uninstaller to complete the removal process.
