1. Windows Update Backup Files Location

This article describes an update for the Disk Cleanup wizard in Windows 7 Service Pack 1 (SP1) or in Windows Server 2008 R2 SP1. This update adds a new plugin to the Disk Cleanup wizard. After you install this update, you can use the Windows Update Cleanup option to delete Windows updates that you no longer need. The item is “Service Pack Backup Files” in the Disk Cleanup tool of Windows 7. Disk Cleanup lists Service Pack Backup Files to allow user to delete and remove the backup files should he or she decides to make installation of service pack permanent, and in the meantime reclaim and recover the disk space occupied by the backup files.

I recently helped out someone who was running extremely low on disk space on their system drive, due to a bloated Windowswinsxs directory. This directory is where Windows keeps backup files for various things such as Windows Server 2008 R2 Service Pack 1. These files allow you to uninstall Service Pack 1, in case you ever actually wanted to do that.The system in question was using about 15.5GB of disk space in that directory. After a bit of research, I discovered the DISM.exe command. When you install Windows Server 2008 R2 SP1, the setup program backs up any files that are replaced by the service pack.

You can remove these backup files to save space with the Deployment Image Servicing and Management (DISM) tool. If you do this, you will not be able to uninstall Service Pack 1 any longer, but you will get back a decent amount of disk space (typically, anywhere from around 2 to 7 GB).You need to open a command prompt with elevated privileges (by right-clicking and selecting “Run as Administrator”). Once you have a command prompt open, simply type this command (shown in Figure 1):DISM.exe /online /Cleanup-Image /spsupersededMicrosoft has a, where you can get more background on this.Depending on the speed of your disk subsystem and the components you have installed, it may take around five to ten minutes for the command to complete. Once it is done, you should have some more free space available on your system drive. After running this command (which you can only do once), I would also manually defragment the system drive.This command will only work if you have Windows Server 2008 R2 Service Pack 1 (or Windows 7 Service Pack 1) installed. If you are running Windows Server 2008 R2 or Windows 7, you really should have Service Pack 1 installed by now.
