Hi, we have a pc with a 240gb SSD that has around 150gb of pointless files. on windows 7 pro 64 bit

79gb of c:\windows\logs\cbs\cbspersist files
75gb of c:\windows\temp files and folders. - lots of cab files e.g. cab_126_2

I've run an sfc /scannow and windows updates. made no odds
I've tried deleting all files/folders in temp folder and it moans that they can't be removed and if i hit skip, it bypasses all of them.

I've read loads of forums about the cbspersist. but no real conclusion on resolving it.
I support over 1200 machines and don't believe I've every come across these files in such mass before

what else can i try

I am fairly sure you can delete the c:\windows\logs\cbs\cbspersist files.

There are files in c:\windows\temp files that cannot be deleted. But most of them can. Try deleting one or two of each file extension and then delete the extensions you can.

Computername.log files can be deleted. One or two may not delete. *.tmp files can usually be deleted.

You can delete most of these files but not with one single delete command.

Another thing you can do (the above steps work) is run Disk Cleanup (Admin tools). Start it, let it calculate, select all the deletion options and then click on Delete Files
