Hi,
The best thing for the drivers would be to use Windows Update, or search the available driver updates for your specific machine...
There may be some available for Windows 10... If not, Windows 8 should work.. There is not much difference..
If you have issues with graphics, the graphics adapter manufacturer would be a good place to look...
A lot of times Windows has a older driver through Windows Updates, but it is one they have certified to work... Hopefully anyway...
If you have any 3rd party Chips, like extra USB or SATA, look for that chip's drivers...
Intel has something called a "Chipset" (INF) driver that in itself is not a driver, but more like a tool to check to make sure the Intel Chipsets are updated properly.. AMD has something similar..
I change a lot of settings... almost to many to list... I was actually going to open up WordPad and make one, but haven't done so yet... Maybe I can do that this evening...
One thing you might check for is "MPEG Video Extension" from the STORE... It enables Windows Media Player and\or Movies+TV to play .mpeg video as well as .mp4, and a few others...
I normally go to "Privacy"... Background Apps... and turn most of them off...
Same with the "Live Tiles" on the Start...
Sorry we were unable to save your previous installation... Reinstalling is a lot of work... especially the programs and Apps...
Considering the circumstances though, you may be better off in the long run with everything fresh...
BTW... There may be nothing wrong with your driver updater program, but I personally just don't trust them...
Windows 10 is pretty good at doing most of that automatically, but sometimes any 3rd party stuff may need some help... I have to do very little on my machine, and it is a Windows 7 SP1 era machine... 2012 I think..
