Windows Update now relies on a combination of active hours, customizable restarts, and manual pauses. The upshot is you can be safe in the knowledge that you’re running the latest version of the operating system without worrying about checking for updates every day.

But there is still one part of Windows Update that needs your attention: the old files that are left behind. They can take up a lot of space. Rather than relying on Windows to clean things up, why not take matters into your own hands?

      How is life made easier? I am at the latest W10 version/update (1709 16299.248) and neither of the above 2 options are available. For 1 maybe it is because the windows.old folder has already been removed. For the other, maybe it is now longer an option because MS has already removed the update files automatically.

        Try Right clicking and then RUN as Admin. It is the only way to get this to work.
