In cases like this I get my Ubuntu disk, boot into it and rename or delete the offending file. Ubuntu doesn't do all the checks Windows does.
Everytime I start my computer, this would pop up.
File name warning
"There is a file or folder on your computer called 'C:\Program' which could cause certain applications to not function correctly. Renaming it to 'C:\Program1' would solve this problem. Would you like to rename it now?"
It goes away when I start in safe mode, but will still pop up when I clean start with only windows service.
The fold is unable to open, has 0kb, and has a shortcut symbol. It was created years ago, but problem didn't show until now.
How can I find what's wrong and fix, anyone ?
