Some Windows 7 and Server 2008 R2 users might face a weird bug which has been confirmed by Microsoft and would be fixed in upcoming SP1.
The bug appears when you set a Solid Color as Desktop background.
- Right-click on desktop and select Personalize option.
- Click on Desktop Background at the bottom of the window.
- Select Solid Colors option in Picture location list.
- Now select any solid color and click on Save changes button.
Now if you try to log on to your computer, Welcome screen would be displayed for 30 seconds before showing your Desktop.
To fix this problem, you can set any image as Desktop background or create a new image in MS Paint or any other image editing software, fill it with your desired solid color and set it as Desktop background.
There is also a registry method available to fix this issue which requires following steps to follow:
1. Type regedit in RUN or startmenu search box and press Enter. It'll open Registry Editor.
2. Now go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
3. In right-side pane, create a new DWORD value DelayedDesktopSwitchTimeout and set its value to 5

4. That's it. Log off or restart your system and your problem should be solved.
NOTE. If you want a ready-made registry script to do the task automatically, download following ZIP file, extract it and run the extracted REG file:
PS: You can also request Microsoft for a hotfix to fix this problem.
BONUS TIP: This bug was also present in Windows Vista and Server 2008, so if you are facing such problem in Windows Vista or Server 2008, you can follow the same steps mentioned in this tutorial.

I never use the solid colours, so this won't affect me. But thanks anyway. :)

I have a problem in Windows 7 Control Panel. The personalization app changes the different settings I make, but I can save thed changes, because they don't reconize any changes.

Actually I have encountered this problem right now.. Last friday (Jan 18) I have set my desktop background to solid color to make it look classic. My desktop requires a password for login, The error in my situation is that the screen lags and I reset twice my PC then I back again with my desktop.
Im a frequent visitor of this site, and its a good timing after that trouble, VG posted the bug! What a coincidence!
I have just applied that solution and I will never set my background to solid color again.
Thanks for the help VG..
