Yeah; was getting memory crashes just with Virtualbox. I suspected (and it was confirmed) those issues were caused by the harddrive having issues (caches memory via using harddrive). Chkdsk (dos method not win10 method) found many bad sectors. Still, I was putting this off now for over 3 months but only a week away from the big OS update (Win10) so decided I would bite the bullet. GIMP kept all my presets and plugins that mattered (user directory had all the settings and when I installed GIMP 2.8.18 fresh, it found everything and was happy) so I'm pretty happy about that. Installed Office 2013 from Microsoft download with no issue either. My system, pretty much, is like it was prior to the rebuild sans a few Give-away-of-the-day freebies and, of course, Photoshop. Have little desire to re-install it; no need, and, soon, enough, GIMP will have high bit depth ability too. I'll just work around the RAW processing (may give the opensource processors another look now anyway). Still like ACR a lot more that any of the other RAW processors out there.
