FIX #2:
Some of these problems are due to a Windows 10 feature called "Dynamic Tick".
Dynamic Ticks are a feature that lets Windows stop the system timer when nothing is happening in order to conserve power. That might sound great, but this can backfire when not operating properly, causing all kinds of freezups and stutters, especially when gaming.
You can disable these Dynamic Ticks without harming your system performance at all, by doing the following:
1) In the search bar on the bottom left, type "cmd" (without the quotes), and then click on "Run as Administrator" on the right of the little window which pops up.
2) At the command prompt, type: BCDEDIT /SET DISABLEDYNAMICTICK YES
3) Next type: bcdedit /set useplatformclock true
4) Restart computer
That's it!
If you want to re-enable Dynamic Ticks, do the same as above, except substitute "NO" for "YES" in Step #2, and substitute "false" for "true" in step #3.
For the nerds, a longer explanation of why this works is below.

There's also a tool you can get to change the value of the system timer, which might be useful for gamers experiencing a stutter: https://www.reddit.com/r/Windows10/c...0_heres_how_i/ .... However, try the above setting first before messing with this.
