In other words it never had SP1 applied, but have had all updates installed individually since Windows 7 came out. I counted 583 windows updates on a PC that had the original Windows 7 installed. I am not sure whether to install the latest monthly rollup first or the "hidden SP2" (kb3125574 - described in the comments below). I am unable to test this properly as of now, but wanted to add it as a hint.


I would try to install in ascending order by KDB number. The list of updates that remains in Add/Remove would seem to be the list of updates that are actually required. TIP, use at your own risk: If you want a list of non-deprecated updates, one option you can try is to get a machine completely up to date by running Windows Updates the normal way, and then run cleanmgr.exe and click Clean up system files and then select Windows Update-cleanup (maybe throw in the log files as well) and then press OK.Īn eternity will pass and all non-required updates appear to be removed.
