a: The generally accepted answer is NO. However, we discovered a command that should free up some space within it.
- Open a Command-Line prompt with elevated privileges (CMD - Run as administrator)
- From the default path of c:\windows\system32> run the following command
- dism /online /cleanup-image /spsuperseded
- We ran this on two Windows 7 computers and the c:\windows\winsxs folder was reduced by 4-7GB
UPDATE: If the device is Server 2008 R2 DISM works great, if the Server 2008 is Pre-R2 you'll have to run c:\windows\system32\compcln.exe. This command reduced a 15GB winsxs folder to 13GB.
