Windows 7 – No Logon Screen Saver – Logon.SCR File?

We have a series of Group Policy settings in place that manage the screen saver settings.

The default screensaver at all client locations with the exception of one, as well as ours is the Logon Screen Saver (Logon.SCR).

It seems that the Release Candidate does not have this file:


Note the Not Enabled symbol over the Screen Saver icon.

When we click on it, this is what we see in the screen saver settings window:


The settings are greyed out as they are managed by GPO. Note the (None) in the Screen saver field.

Hopefully this gets rectified before RTM, or we can copy in the Windows Vista Logon.SCR file to make up for it.

We shall see…

Yes, I also found this out. The Logon screensaver is a nice gadget.
Is there any Way to modify the Vista Logon.scr with the WIndows 7 logo?

Right now, not that I know of. I have bugged the problem on Connect.

I do believe that it will be there when the time comes ... at least I hope so!

I have noticed this as well on the RC. When I exit RDC, the login screen just sits there, no screensaver.

Still an issue in Windows 7 RTM. Is there a new way to accomplish locking the workstation after being idle?

I logged the logon.scr loss on the Windows 7 Partner forums and the answer was "by design".

Apparently a number of existing screensavers are gone.

So, what we will be doing is reworking our security groups by adding one for Windows 7 users and configuring an Enforced GPO that sets a Win7 built-in screensaver.

More to come on that ...

It looks like you need to specify scrnsave.scr instead of logon.scr now.

From what I can tell this has existed since Windows 2003.

Of note is the filesize difference. I would guess this means that memory and cpu usage go down as well.

Windows 2008
logon.scr - 5.4MB
scrnsave.scr - 10K

Windows 2003
logon.scr - 498K
scrnsave.scr - 9K

My guess is that with LCDs so prevalent now and the need to limit power usage, the days of graphical fun screensavers are behind us. It's best just have the monitor go blank then turn off.

I'm also all for saving whatever cpu cycles and memory I can, especially when virtualizing.

Couldn't paste a picture here so
I posted details on the GPO needed here

It seems that you are right about the commonality of the scrnsave.scr across the operating system line.

It may take a bit of convincing at this point to switch over, but it may be possible.

Thanks for the pointers.

You can set Windows 7 to work like Windows XP and work on your domain. Go to: for instructions. As for the logon.scr do a google search for "Windwos 7" and logon.scr and you will find one to use or go to:
