Win8.1 has a lot going for it admittedly, unfortunately functionality isn't among that. Logging into another computer connected via LAN twice and with significant delay? No go. Fake writing .wim files? No go. Maybe I should have spent time figuring out why Win8.1 behaved like it did, but the incentive to do so was practically non-existent when Win7 is just a reinstall away.Win8.1 is very good. Significantly better than 7.
