Install Disk Cleanup without Rebooting Server

If you’re on Server 2008R2 and want to install Disk Cleanup, Microsoft tells you to install an update or two, enable a Windows feature, and reboot the server.

What they don’t tell you, but hide on a small TechNet article is that you can “install” disk cleanup yourself by copying two files. Basically, you’ll need to find these two bad boys if you’re running 64-bit Windows:

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

The cleanmgr.exe goes in Windows\System32 and the cleanmgr.exe.mui goes into Windows\System32\en-us folder. That’s it!
