One thing I have noticed from personal experience, is that Windows 10 can attempt to install the latest hardware drivers if it sees them available.  For Intel based systems, that could be chipset drivers (motherboard features), Management Engine drivers (deals with power settings, etc.), and video drivers if using the integrated Intel HD graphics.
 
If you have any system instability issues, it's a good idea to check with your PC or motherboard manufacturer for their version of the Windows 10 drivers, or check with their support groups if you have any questions.
 
In my case Windows had installed the very latest version of Intel's drivers. I was having trouble with some shutdown's hanging, a few blue screens, etc.  My mobo and BIOS are a couple of years old.  When I rolled back to my manufacturer's (Asus) driver versions, which were slightly older but still Win10 compliant, everything settled down. 
 
I have always heard that the best advice is to never get your drivers from Microsoft, if there is an alternative.
 
From now on, this will be at the top of my checklist after any Microsoft upgrades ...

Haven't used splat much since moving to Windows 10. However....
 
Windows 10 is full of inconsistencies and bugs. The constant updates fix one thing and mess up a dozen others.
 
This morning I logged on and used Edge with no issues. Then I shut down to re-insert my secondary harddrive which I share between 2 computers, and now Win10 refuses to let me use Edge while logged in to the "built in Administrator" account. 1st time for that.
 
The age old "Show windows side by side" issue still looms.

no problems...after aniversary win 10 update.
