No display properties at all. (WXP-Pro)

[TheSkull]

I think I misunderstood some advice from a post by Patrick O Brien and used it incorrectly and caused a bigger problem for myself.
Under my display properties, my "select screensaver" option/taskbar has been grayed out. Including the option of selecting password protection. So I was looking for something in the regedit that might be deactivating it.
So I went to regedit and removed:
HKEY_CLASSES_ROOT\CLSID\{4c892621-6757-4fe0-ad8c-a6301be7fba2}
thinking it was what was blocking my screen saver options.
Now when I right click on the desktop and select "Properties" nothing appears at all.
Can someone please help me restore the display options and screensaver options? I know how to remove things with regedit but not how to add things. Not sure what to add if I did know how.
Thanks.

Open system restore, choose a restore point, and return your computer to its previous stable state.
If you have system restore disabled, try this:

Thanks. I am afraid I disabled restore point.
So I copy and paste the stuff you gave me into my regedit. What do I enter it as? A key or a string or a binary value or what?
Sorry to be so cluless, I appriciate your help. thanks.

Read <a target="_blank" href=http://www.winguides.com/article.php?id=1&page=4&guide=registry>Importing and Exporting Registry Settings</a>.

In brief:
1. Create a .REG file. You can do do this using the Registry Editor: select a key, then from the "Registry" menu choose "Export Registry File...", choose a filename and save.
2. If you open this file in notepad (right click this file, choose "edit") you will see a text similar to the one I posted:
Windows Registry Editor Version 5.00
...
3. Replace all the content with the text I posted previously (31 lines, begins with Windows Registry Editor Version 5.00 line), save it.
4. Right click this file, choose "merge". Or, double click this file. Reply "yes" when prompted.

Windows restart may be required for the changes to take effect.
