So this update supposedly contains Windows 10 Upgrade stuff BUT on the other hand, it also fixes a problem with Windows 7 that makes the system sit there for ages looking for updates. So I am not sure anymore if this is good or bad to install? People sometimes complain to me that their Windows update takes ages to find anything, and while I know this would fix it, I am concerned about installing it if it contains update to Windows 10 Can someone shed some more light on this please. If one doesn't have any of the other Windows 10 upgrade updates, would this actually activate any Windows 10 upgrades or does it work in tandem with other Win 10 upgrade updates?
