Windows 7: Show File Extensions and Hidden Files for all Users

Show File Extensions and Hidden Files for all Users


I am trying to change the registry to show hidden files/extensions.
This is for an unattended install, so I don't want to do it manually for each user. I know I can change the registry for the current user, but I can't seem to find out how to do this system wide. I need to show hidden files and file extensions for all users, such as when a new user account is created, extensions and hidden files are shown.

Is there a way to do this system wide?

I have tried adding the dword following entries:
Hidden (Value=1) & HideFileExt(HideFileExt=0) to the below locations in the registry


I read that if you change HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\NoHidden & HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\HideFileExt to the above values it should change the default key for HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced (Hidden & HideFileExt)

None of the HKLM entries I have tried as above appear to work.
Is there actually a way to change this system wide?

show and hide files is a profile specific key and therefore can be modified by user accounts. if you would like to change the default, navigate to key:
HKLM\software\microsoft\windows\current version\explorer\advanced\folder\hidden and \hidefileext
there are keys in there that set default behaviors.

Which key and what value in \HideFileExt & \Hidden requires changing?
Does this change the default value for the profile specific values under HKCU?

I did already try to change/create every value that appeared applicable, none of the values I changed under HKLM had any affect. I assumed the values are the same as when changing this under HKCU and did change the dwords to the same.

I would do this by customizing the default user profile, simply selecting Show hidden files and folders and Show extensions in folder options and copying this setting to default user profile which is then used in all future user accounts.

See the Seven Forums tutorial for customizing the default user profile: User Profile - Customize During Installation

However, as Tews mentioned, users can always change this setting.

Ok, thanks. As long as I can show hidden files and extensions when a user logs in for the first time, that is all I want to do.
I'll try customising the default profile.

It's not possible to change this system wide via the registry?
