After the a guest windows 7 boot up, when I open Outlook 2013 or Chrome or other apps like Word or Excel, the app just closes. Chrome upon reopen say it died un-expectantly and do you want to restore, sometimes Excel crashes so fast an autosave restore can't get some work I've done back. I'll be in the middle of an email and BAM outlook closes, I've re-installed parallel tools and sometimes while it starts to install the tools installer goes away. Anyone seen this issue?
