Regarding Auto-update. Microsoft recently announced the end of support for Win-7 and released the final patch, which caused users a lot of problems. I was saved from them by the fact that I have the habit of disabling Auto-update where possible and updating everything manually. Hopefully, Auto-update will not be in the future, the only way to upgrade?
