As part of my computer clean up process, I always use the Disk Cleanup tool in Windows 7, but no matter what I do, as time goes by the available hard drive space keeps shrinking anyways. Apparently in the case of Windows 7 Service Pack 1, one of the reasons is that the OS doesn’t flush outdated update backup files, which are kept in the WinSxS folder if there is a problem and rollback is necessary, and over time these files start to take up a large part of the disk space.
Trying to mitigate this bloating problem, Microsoft released a new update for all Windows 7 SP1 PCs that allows users to delete outdated update files when using the Disk Cleanup tool. Basically when you install the new Hotfix (described as KB2852386) a new option will appear called “Windows Update Cleanup”, just select the option when using the tool and you’ll be able to gain more disk space in your system.
There is one more thing… When you open the Windows 7 Disk Cleanup tool, you won’t see the new option right away, you need to click the Clean up system files button.

Although, this is a welcome option to have in the operating system, the amount of disk space you can recover is minimum. We’re talking about 100MB to 500MB and maybe a bit more, but that’s just it.
To download the Hotfix KB2852386 follow this Microsoft link. There you’ll find a x86 and x64 version of the update.
Windows 8 already comes with the feature, so there is nothing to install. Just open the Run command and type cleanmgr to launch the tool.
