Installing SP2 and SP3 in XP and SP1 in Vista - you can use your PC, just reboot it and all is done.
Win 7 - ‘installs’ SP1 for like 30 minutes, and now “Restart your PC, installing SP1 may take an hour or longer”
EXCUSE ME?! WHAT THE FUCK WERE YOU DOING JUST NOW THEN? NOT TO MNTION THIS IN TOTAL WILL TAKE WAY MORE THAN INSTALLING Win7 IN THE FIRST PLACE
