The added features and useful updates are the main reason why people go for Windows Server series at the first place. Windows Server is an amazing operating system specially designed for small to medium enterprises. However, many people experience low disk space on Windows server 2008 and 2012 R2. And if you’re reading this article, there are greater chances that you’re experiencing low disk system space and unable to find the disk cleanup tool in the server.

Enable/Install disk cleanup server 2012 r2

I’m amazed myself because they didn’t add the disk cleanup tool (cleanmgr.exe) in Windows Server 2008/2012 R2 by default. But you can still enable this option by using a Server feature known as “Desktop Experience”. However, after enabling the Desktop Experience, you must reboot your system. Moreover, it installs many other components, tools, and updates on the computer. Anyways, if you are willing to reboot the system, follow the steps below

  • Simply go to Programs and Features
  • Under the Features Section click on Enable Desktop Experience
  • Done!

Solution 1 to Enable Disk Cleanup Server 2008 R2 without a reboot

Copy the files at the following location

  • C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7da\cleanmgr.exe
  • C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.1.7600.16385_en-us_b9cb6194b257cc63\cleanmgr.exe.mui

After you have found the files, copy the file cleanmgr.exe to C:\Windows\System32\, and copy the cleanmgr.exe.mui to C:\Windows\System32\en-US\. After this

  • Press Windows+R
  • Type “cleanmgr” and press enter
  • Disk cleanup will pop-up
  • It’s that simple

Solution 2 to Enable Disk Cleanup Server 2012 R2 without a reboot

Unfortunately, Windows Server 2012 R2 does not support the above method and shows an error message if applied. Therefore, you must use the Desktop Experience feature to enable the Disk Cleanup utility. However, you can still use the following method to enable disk cleanup

  • Install Desktop Experience
  • Reboot the computer
  • Copy these files %windir%\system32\en-US\cleanmgr.exe.mui and %windir%\system32\cleanmgr.exe and paste them to any directory
  • Uninstall the Desktop feature
  • Reboot the server
  • And then copy the above files to the same directories as in Windows Server 2008 R2

  • Open each partition and move the unallocated space to the left until it reaches right next to c drive
  • Skip the above step if unallocated space is already adjacent to c drive
  • Open the c-drive and acquire the unallocated space
