After finishing Windows updates, will i get banned again?
If it's strictly updates, no, if it's moving from one service pack to the next (Windows XP SP2 to SP3) or Windows 8 to Windows 8.1, there's a chance that could cause an issue, especially the latter. I'd advise not to do such until after Vice War.
And of course, OS reinstall and/or upgrade will cause UID mismatch
