Hi tom,
Safe mode does not allow creation of folder or text file, but the message is different:  Can not find/load module.
Re article:
I disabled the antivirus - no change.
BTW, I can not create a restore point in Safe mode; but I can in normal mode.
There was a strange message when I did --- attached in next post.
I tried methods 4 in the Auslogistics message you cited.  No change.
Then, I tried method 3 in the Auslogics message you cited; did this after 4 because it seemed more complicated.  But, not able to execute reg script.  See message in next post.  I did iw one with the "Windows Registry editor ..." as the first line, but I got message "not a registry script"  Then, I eliminated the first line and tried again.  Same result.  Not a registry script.
