NO GP CONTENT..
This one has been annoying me for a while; so I found two resources which explain how to stop Windows 7 from taking (literally) forever, or at least hours to update.
Resource 2 at Stack Exchange. Look for the words “This issue has come and gone over the years with different fixes along the way…” and follow his instructions. Worked perfectly for me. Requires downloading two patches, then going offline, installing them, then going back online to complete. Again: Personally worked for me and I can vouch this worked as expected (in my cases anyway.)
Hope this helps you !
