server 200r2 is out of disk space on C: I have moved everything that was easy to move on to D:
As a result of an avalanche of Microsoft updates last night the Winsxs directory now contains 18Gb.
ccleaner.exe and/or 'Disk Cleanup' only recovers small amounts which are immediately eaten by processes on the system.
I have KB2852386 and installed desktop experience.
When I run 'disk cleanup' it identifies 6.2Gb of update files which it says can be removed.
Then I have to reboot at which point I get "Failure configuring windows updates" and it all rolls back again.
I disabled the windows update service and then I deleted the WU download folder as well, but none of this makes any difference.
To make some space I uninstalled all the office updates which were delivered yesterday.
How can I make 'Disk Cleanup' do what it is supposed to do and free up 6.2Gb?
I tried running a downloaded script 'cleanup-disk.ps1' but all it seemed to do was display its contents in editor.
