Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

MW2 Problem

I think the game is booting, then Steam is trying to boot, but is hanging during the login process, hell it may be sitting there wait for you to enter your password.

Try this, turn Steam On and log in. Click on the game listed in the "My Games" tab to start MW2 and see if the problem continues. If that does not work, you have 2 other suggestions above.
