How to Show Hidden Files Using Registry File

Posted by Britt Duncan - January 29, 2015

As some users may find that changing the settings in Folder Options won’t help to reveal hidden files. This can be tricky as some Trojan viruses set their files as invisible to protect themselves. What’s more, the access to registry editor may even be cut off. In such cases, how can you see the protected files? Here comes the solution.



If you have troubles accessing the Registry Editor, go through the steps below to change the settings first.

1. Type gpedit.msc in the Run box and hit Enter.


2. Locate User Configuration -> Administrative Templates -> System. At the right session, double click on the item of Prevent access to registry editing tools and mark the option of Not configured.



Restart the machine and you can continue the following steps.

1. Tap Windows Key + Q to activate Search function, type regedit and press Enter.


2. Once the Registry Editor opens up, navigate to the following registry branch: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL


3. Move to right hand pane, find a item named Checked Value. Right click on it and set its value back to 1 if it has been set to others.


4. In case that the file type of this key is changed to others other than DWORD, you have to delete it and create a new one by yourself. Right click in the blank space in the right pane and select New-> Select DWORD(32 bit) and name it as Checked Value. Double click on the newly created key and set the value to 1.


That’s all it takes. Now, you can reboot the machine and see whether you can see the hidden files successfully.
