Summary: Screen savers are easy to locate and delete, unless they're one of the default set included in Windows. Then extra steps are needed.
Yes you can. It's just a matter of knowing where Windows stores them. Oh, and then perhaps beating Windows over the head a little as it tries to restore these "critical system files". • Screen savers are easy to locate. Windows keeps them in the SYSTEM32 folder within the Windows folder. The file extension is ".scr" for "screen saver". Here's a list of the default screen savers that came with my new machine located in the c:\Windows\system32 folder:
One would think that deleting them would be a simple as ... well, as simple as deleting them. "The default Windows screen savers are apparently protected by 'Windows File Protection'."
If you're deleting a Windows default screen saver, there is no such luck. The default Windows screen savers are apparently protected by "Windows File Protection". This service of Windows monitors for files which are changed or removed without Windows knowledge. The idea is that by making sure only "official" copies of important system files are present, any attempt to replace them with broken or malicious copies would be detected and reverted. And by reverted, I mean that the original copy of the file would be replaced. So, yes, go ahead and delete one of the default screen savers. And then watch it quietly and magically reappear a few minutes later as Windows File Protection performs its magic. In an ideal world one would go to Control Panel, Add/Remove Programs, and then Add/Remove Windows Components where you'd find something relating to the screen savers. This is not an ideal world. There's actually no option to remove the screen savers. So this is where we get tricky. When Windows restores a protected system file it does so from a backup copy. If we delete both the original and the backup, then Windows would have no way to restore it. As it turns out, the backups for the screen savers are kept in c:\windows\system32 are kept in c:\windows\system32\dllcache. Delete the same file in both locations, and the screen saver is gone. But it's still not quite that easy. Once you delete them both you'll get this warning:
Why Windows screen savers are "required for Windows to run properly" is beyond me, Windows runs just fine without them. So, click Cancel, and you'll get yet another dire warning:
Note that the error message is actually incorrect: we don't have the "wrong" version, we have no version at all. Particularly when it comes to screen savers it's fine to say Yes, and keep these nonexistent "unrecognized versions". By and large it's safe to delete screen savers, though if you're at all nervous then by all means copy them off to another location, back them up or burn them to CD to save them "just in case".

Why go to all this trouble to delete a few screen savers they only take a tiny bit of disk space the average disk is measured is 40 GB up to 1 TB the default screen savers take less the 10 MB. Sounds like more trouble than it's worth.
Posted by: Albert Taal at April 25, 2008 08:25 PMIt's not always about disk space. I work in a large corporation where IT automatically runs a daily job on my PC that (among many other things) enables a screensaver. They do this as part of a security policy which requires re-signing on after an inactivity timeout. But I want to control this myself. When I'm in the office, I want my PC (a laptop) to remain on with the screen going dark after 10 minutes of inactivity without the need to re-sign on again. When I'm on the road, I always turn on the "Prompt for password when the computer resumes from standby" option. So in my case, I want to delete the screensavers as one means of trying to circumvent the action of the daily IT job. Also, running a screensaver is definitely not very green, since it uses more power than simply using the Power Options to make the screen go dark after a timeout.
Posted by: Geoff Walker at April 27, 2008 09:41 AMDude! Thanks so much. I was wondering how to do this. I clicked a bad .exe i downloaded and it installed spyware on my computer. I deleted the spyware part, but all these beetles would appear and gnaw away at my screen saying: "your computer might have spyware" (this was an effect of the spyware). Now both the spyware and the nasty effect is gone. Thanks so much!
Posted by: Daniel at May 15, 2008 07:46 PMI did the delete trick in both locations, but the name of the screensaver still remains in the list of screensavers. I can click on the name of the screensaver and it says it has been removed. Just reboot for total removal. This did not remove it either.
