Thank you for all the info! I had the POSReady key enabled for a while until in 2017, one of the updates broke the whole install. Could barely run 3 hours before running out of resources. I ended up reverting to an Acronis image from 2013 (wanted to get rid of some other installs too). I disabled updates, ran the Offline Update iso I made in summer 2014 (with all the last non-POS updates). After several incidents where I got a virus just from opening a website in Firefox (staples.com and newegg.com had 3rd party ads with virus payloads!), I installed VMWare Player 6 with Linux Mint Rose Mate 17.3 (love this flavor) with Firefox. Thunderbird in Linux for email. No more issues with viruses. I always fix virus attacks properly- by reverting every PC on my network using a prior Acronis image and AV scanning every drive. No small feat with 14 or so boxes and ~100 drives (yes this is at home- friends tell me I'm a computer geek). So I run XP with no updates past April 2014, and get away with it by using Linux to sandbox my web browsing and email.
