How to: Reclaim Server Disk Space

Here’s what we can do to save disk space on a Windows OS drive.

1. Run Disk Cleanup – if the server does not have disk cleanup, you can install only disk clean up like this:
The process involves copying two files in the C:Windowswinsxs directory to a specific location
Windows 2008 R2
C:Windowswinsxsamd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7dacleanmgr.exe
C:Windowswinsxsamd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.1.7600.16385_en-us_b9cb6194b257cc63cleanmgr.exe.mui
Windows Server 2012:
C:WindowsWinSxSamd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.2.9200.16384_none_c60dddc5e750072acleanmgr.exe
C:WindowsWinSxSamd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.2.9200.16384_en-us_b6a01752226afbb3cleanmgr.exe.mui
Once you’ve located the files move them to the following locations (Server 2012 non-R2 and earlier):
Copy Cleanmgr.exe to %systemroot%System32.
Copy Cleanmgr.exe.mui to %systemroot%System32en-US.

2. If Active Directory Certificate Services is installed you can clear the CA logs like this:

  • Open the Services MMC and stop the Active Directory Certificate Services service.
  • Make a backup copy of ALL the file contents present in the c:windowssystem32certlog folder.
  • Delete EDB.CHK and all the files that have an extension of .LOG (*.LOG)
  • Restart the Active Directory Certificate Services service.

3. Clear any IIS logs

Clear all IIS logs from c:inetpublogs

DO NOT delete thhe folders, just the logs inside them. There is no need to stop any services to delete these.
