Get KB2852386 for Windows 2008R2 and Windows 7 from below locations: http://www.catalog.update.microsoft.com/Search.aspx?q=2852386 https://www.microsoft.com/en-us/download/details.aspx?id=42739 Server needs to be rebooted after this update installed. Install Desktop Experience feature. When installing Desktop Experience, it does require additional features. Select the button to Add Required Features and click Next and then Install. A reboot is required to finalize the install. Run cleanmgr.exe. Several options are provided for cleanup, including a new option for Windows Update Cleanup. Just like the Windows 7 cleanup, mileage will vary. Also like Windows 7, the actual cleanup occurs during the next reboot. After the reboot, taking a look at the WinSxS directory, it has shrunk. Other options: If you have applied SP1 and have not cleaned up afterwards, I’d highly recommend doing so by running the following command from an administrative command prompt: dism /online /cleanup-i

If you want to set the output of a command to a value you have to capture it in a  for  statement like this: for /f "tokens=2 delims=:" %%a in ('systeminfo ^| find "OS Name"') do set OS_Name=%%a Then remove the leading spaces like this: (there is probably a better way to do this) for /f "tokens=* delims= " %%a in ("%OS_Name%") do set OS_Name=%%a A few things to note here: 1.)  "tokens=2 delims=:"  is setting the delimiter to  :  and it is selecting the second section only, which will pull only the part you want.  2.) the  |  is escaped with a  ^ , this needs to be done in  for  loops or anything after that will attempt to execute as seperate commands.  3.)  "tokens=* delims= "  The token here is * which is all tokens. ======================= Examples of WMIC output to variables: echo WMIC output to variables for /f "usebackq tokens=1,2 delims==|" %%I in (`wmic os get name^,version /format:l
