Installed it this morning. I have not experienced any problems at all .. all programs are working and performance is good. I did a system image .. and created a system restore USB drive, everything went very well. I am ready to enjoy this new product. Pretty impressed so far with what Microsoft has done.
I've got Windows 10 running on an old self built dual core Atom PC, everything runs better than Windows 7 and 8.1. It's pretty amazing to see this little PC running as well as it does, so yeah, I like Windows 10.
I have actually started to like store, but I really hate the colorless top bar in windows, it is ugly.
Most of us here on the forums have been using Win 10 for months, so obviously we like it to at least some degree or we wouldn't be using it this long.
Personally, it seems whatever they did with the patch ("Day One") on release seems to have introduce a few bugs that weren't present prior.; but in my case pretty minor problems so far.
This morning IE 11 would not scroll down. No problems clicking on the different stories on msn.com page.. just could not scroll down. Restarted several times and now working again.
How do I know if Windows 10 is updating? There's no update icon in notification area.
As posted above I've been using 10 in preview for some time and I really like it and with the final(29th) upgrade it's perfect for me at least.
