Reset SoftwareDistribution Folder

Occassionally, Windows Update process stops cleaning up or something and the C:\WINDOWS\SoftwareDistribution folder starts to get full.


To reset this, stop the service, rename the folder, and restart service.  This should create a new SoftwareDistribution folder:

• Open a CMD window runas admin
• type net stop wuauserv and press enter
• type rename c:\windows\SoftwareDistribution softwaredistribution.oldand press enter
• type net start wuauserv and press enter
• type exit and press enter

Reboot and if all is well, you can delete the old softwaredistribution.old folder.

Large CBS folder in Windows 2008 R2

Possible fix to problem of running out of C: drive space due to log/cab files filling up C:\Windows\Logs\CBS folder...


To reset the compression in the CBS folder use the following method:

1. Disable TrustedInstaller.exe (Windows Module Installer) in Taskmanager Services
2. Delete all the .log files in the C:\Windows\Logs\ CBS directory, delete the .persist and .cab files as well
3. Enable TrustedInstaller.exe again

NOTE: Cleaning up the CBS folder resets the compression process, so the new created log files should not get bigger than 50 Mb before the compression into .cab files as it should be.
