I also use fences from the same company, Stardock and after the reboot I was unable to move any icons on my desktop. Again, the fix was to download the latest release which I believe is 2.11, install it, reboot and all is well.
The only real problem I have is my very expensive RAMDisk software is now mute. The folks over at Roxio only allow installation on Windows 8.0 and not Windows 8.1. I'm going to have to email their support folks and see if I can get an upgrade or fix. I wish I would've known this ahead of time because all of my browser cache was in a RAMdisk and I was wondering why my browsers were crashing all over the place. Now I know.
Also, SBS users might want to check out this post. You... will not be happy. I know I would not be.
Otherwise, the upgrade actually went pretty well.
I do highly recommend that you check with your OEM or motherboard manufacturer and make sure that no specific Windows 8.1 drivers are needed. The way you would know this is you would see a section directly relating to your notebook, desktop system titled Windows 8.1. This is more of a precautionary measure but I highly recommend you do it anyway.
As I said, I just got finished but I wanted to let you all know that even on my pride and joy system the Windows 8.1 upgrade went pretty smooth. It took my system about 30 minutes to complete the upgrade but I got it right when it was released so the download was actually relatively fast.
If you're in the mood to give something a shot, and you own Windows 8.0, you might want to give this a shot. So far Windows 8.1 seems a little bit speedier but otherwise it really 'feels' like Windows 8.0.
Anyway, good luck to you all.
I will have more on this later after I had some time to play with it.
