>>106169042 (OP)10/11 has the benefit of cumulative updates, unlike xp and vista (plus 7 and 8.x until late 2016)
>these updates have been going for over a fucking hourno shit. SP3 XP was released back in 2008 - 5 years worth of QFEs until the final EoS (or 10 if you were piggybacking off POSReady 2009 updates.)
and with the way how the Windows Update stack works (the client/agent part, exactly) by querying the update metadata database (WSUSSCN2 - contains update metadata as early as W2K, including superseded) for any applicable updates, don't be surprised it takes that long, as it needs to scavenge through all that shit.

if you really cared then you would've had slipstreamed unofficial service pack 4 into the installation image.
