If the option to enable "Show Hidden Files and Folders" is MISSING from your Folders Options > View > Advanced Settings

Get Show Hidden Files and Folders Back if it is Missing

Find this key in your registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden]

Modify the string value "Type" and enter "group" as value data.

After the edit is complete hit F5 to refresh, and go look in your Folder Options.
