Recommended Posts

Posted · Original PosterOP

I just got a message saying my storage was full on my laptop, knowing I've only used about half the storage I did some digging and found this huge file at C:\Windows\Logs\CBS 

I've got a few questions

What is this?

Is this safe to delete? 

If not what can i do?

from a MS technet:



We also need to temporarily stop WMI:

  1. Stop the Windows Modules Installer service. Click Start and in the Search box type: services.msc Press Enter and you see the Local Services list.
  2. Scroll down to the Windows Modules Installer service and double-click on it.
  3. Under Service status, click Stop. Click OK.
  4. Use File Explorer to go to C:\Windows\Logs\CBS. (If Windows is installed on a different hard drive, you have to go to that drive.)
  5. Move or rename all of the files in that folder.
  6. For good measure, delete all the "cab*" files in your Windows Temp folder, typically C:\Windows\Temp. Makecab won't ever delete them, so you get to.
  7. Reboot.

When Windows comes back, the Windows Module Installer service will be running again,
