However, if you still are not able to see hidden files and you come back to the Folder Options window and find that the ‘Show hidden files and folders’ has reverted back to its unchecked state, then read further.

First Reaction

The most logical thing in such a case would be to check for viruses, trojans, spyware and malware. Use well-known free or paid virus scanners and anti-spyware tools. Hopefully, after cleaning, if you come back to the Folder Options window and check ‘Show hidden files…’, it should work.
