Over time, Windows Updates files are superseded with latest updates and the previous superseded updates remained and it takes storage space.

When the updates are stable, the superseded updates is no longer needed and we can free up the space. The Windows updates are stored in “C:\Windows\WinSxS”.

In Windows 8.1/Server 2012 R2, you can use DISM.exe to perform cleanup.
