I got a notice from Microsoft MSDN/Technet to try the new Windows 8.1 Enterprise eval version. It said it was good for 90 days, so I thought I'd give it a try to see what it was all about. Eveh thought I knew it was only good for 90 days, I thought I see if I could fool Mr. Softie. I had planned on making an image of the base installation and then in thirty days, restore that image, and see if the counter would stay at 90 days left, or update to 60 days. Probably a long shot, but I figured I give it a try. I downloaded the iso directly from Microsoft and burned a DVD using ImgBurn. Then I cloned my working drive with Acronis to a spare hard drive. My working drive is formatted at 3 partitions. One 60GB boot partition, one 60GB backup partition, and one 650GB partition for digital packrat storage of various iso's. After I cloned the Working drive to the spare drive, I booted off the working drive, and then formatted the cloned drive's boot partition. I did a quick format, not the destructive one that takes forever. Then I shut down the computer, and disconnected the working drive, just in case Windows 8 took a look around and decided to install itself where it wanted, and not where I told it to. With only one drive in the system, and the C: boot partition formatted, I figured what could go wrong. Windows 8.1 installed no problem, it showed the one drive, and installed it on the C:\ boot partition, and started right up, no problems. But when I switched to the Desktop my old Desktop background image was there. At first I didn't think too much about it, but as I thought about it more, I couldn't for the life of me figure out how Windows 8 found, and installed my desktop background from a Windows 7 installation that was on a hard disk that was unplugged. When I looked at where the image was stored the mystery deepened. It was stored not where I kept it on the Windows 7 installation, but in another location that I never knew existed... C:\users\al\AppData\Local\Microsoft\Windows\Themes\RoamedThemeFiles\DesktopBackground\hubble_ultra_deep_field_orig_2.jpg Here's what it looked like, and it had a file creation date, of the 19th which is when I did the initial install of Windows 8.1 The bizarre part is that I never kept the file there, and the file size listed is different from the file size of the original file. I have a bunch of stuff that I keep in one sub-directory and copy it to the Windows directory on any new installation. The only problem, is that I hadn't copied this directory yet. Here's what the original files, and location are on the Windows 7 installation. Keep in mind that this hard drive is powered off. I thought maybe when ImgBurn created the Windows 8.1 iso it somehow magically behind the scenes copied some additional files, but I searched the DVD and no file showed up with Hubble anywhere in the file name. So the $64,000 question is how did Windows 8 know that this was the desktop background from a Windows 7 installation on a hard drive that was powered off. Try as I might, I couldn't come up with any reasonable answer. Maybe someone here can. And on a more pleasant note, I can attest that PatchPae2 works just fine on Windows 8.1 and even though I installed the 32 Bit operation system, it happily reports the full 6GB or memory I have installed.
