I'm a fairly accomplished computer user. I use win xp and 7 at work (but those machines are locked down by corporate IT) and macs at home. I'm not proficient in Win 8.1 on my new Surface pro 2 (got it yesterday, spent the first night doing windows updates). I've seen the manual that MS has online and the startup videos, but could you direct me to a general how-to book for win 8? Thanks in advance!
