I have had the same experience. Upgraded from 2013 to 2014, ran Registry Cleaner, almost 2000 errors found (a clue right there...), ran "Fix", created a backup, and rebooted. Windows said it was settuping up for first use during reboot. Blood drained from my face. Same problems as noted above when it started. Tried restoring backup from jv16, no help. Went to do a system restore. No restore points! They had all been wiped : Now I am stuck. Cannot start IE, Chrome, or Firefox. Thank you very much Macecraft Any suggestions? Please!
Windows 7 64 bit - all up to date - at least until last night...
Thanks for any help.
