I've been on Windows 10 for almost two months now. So far... it really doesn't feel all that different to Windows 8. I'm still getting used to the fact that I need to move the mouse to the left side of the screen instead of the right side to sleep/shutdown/restart, and I had to create quite the ridiculous workaround to get the calculator to come up with a keyboard shortcut, but so far there's very few differences.
I'm also not surprised that it can run on hardware that old. Windows 8 was sort of designed to be the one OS Microsoft could load onto any device they wanted, thus eliminating the need to have multiple OSes, which meant a lot of the overhead and bulk which slowed down XP, Vista and 7 was eliminated.
In terms of compatibility, Windows 10 is on par with Windows 8. A few things work better, a few things work worse, but it's mostly the same. I did go through and disable a whole slew of options, plus since I'm on Pro I switched over to the alternate branch which delays updates for three months. Win10 seems to be fairly decent at figuring out when I'm not using my system, though it only waits through about five to ten minutes of complete inactivity before it will decide to do updates and restarts if it has any planned, so I once came back after preparing food only to find the thing had done a complete restart and thus all of the things I had opened weren't open anymore.
That's when everything's working properly though. I had a Hell of a time getting my graphics drivers working properly, plus I was finding my system was constantly waking up from sleep and going back to sleep because of how the task scheduler was interacting with my virus scanner's scheduled scans. Edge is still pretty buggy and many websites don't work properly in it, so I'm still using a combination of IE and Firefox.
Dad on the other hand has been having some incredibly bizarre issues since his system updated. For instance, every time it boots up it tries and fails to load a DLL file called, "GrudgerHumpier.dll", or something along those lines, and attempting to search the net for info on it pulls up nothing, and when I try to go excise this from the system bootup process it's nowhere to be seen in the registry tables or elsewhere. Also, every so often, his task bar just stops working. You can still highlight things on it and when you click it looks as though it registered the click... but then nothing happens. Keyboard shortcuts to use it fail to work as well. I have not had any issues like this at all. :o
