How to free up disk space from old Windows updates
Over time, the size of the Windows installation on the Reference Device and in the OS images will grow as Windows Updates are applied to the system.
Warning: While I have seen no negative impact by using above methods, you should use them carefully and understand that they are performed on your own risk. Make sure you always have a backup in place before start makinging any changes to the Windows Installation and the production image!
Another thing I figured: cleanmgr /sageset , if there are Update System Files button, click it first, then tick everything, and click OK. It saves the settings to registry.
When you want to execute it, just run cleanmgr /sagerun.
It takes care of SoftwareDistribution, among a lot other places too.
Thanks for the contribution Eiris!
I'm using sageset option almost all the but like to save my personal settings in a seperate profile. For example: cleanmgr /sageset:1 to store, and then cleanmgr /sagerun:1 to load the stored configuration and initiate the cleanup easily with a shortcut on the desktop.
Cleanafterme is also one of my favorites when preping an Image for distribution. I'm using it on Win7/8/8.1 w/o issue, but again, this is on your own risk.
