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.
