disc cleanup

Hello

When I click disc cleanup and after it has run there is an option to cleanup system files.

If I click it, it says to clean up Windows update files with usually  quite a number of MBs.

When I click this it usually takes about 5 minutes to run.

First with Win 8.1 should this be done and secondly will this damage any important functions like restore points?

My desktop handles it well but the desktop gets pretty hot to get it done.

Is performing this an over kill?

Thank you

Peter

Not sure if this will prevent you from uninstalling a Windows Update or not but I do think you are overdoing it, unless you are tight on drive space.

I am glad I asked; it is one less thing to do. Thanks.
