I couldn't start my system - got an error message saying that
windows\system\config\system32 is either corrupt or missing.

So, I followed the procedure on the Microsoft site to address this.
Part 2 of the procedure calls for the latest restore points to be
copied to the temp folder and then used. I can't find the system volume
information folder to be able to do that. I've already done the "show
hidden folders" etc., but this folder is still missing.
