"REGEDIT /S regtweak.reg"

and my regtweak.reg

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]
"Wallpaper"=""
"WallpaperStyle"="2"
"OriginalWallpaper"=""
"SCRNSAVE.EXE"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"UIHost"=hex(2):43,00,3a,00,5c,00,69,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,73,\

I could not understand why the HKCU don;t apply and the HKLM do.

After some research I got the idea to set the explorer hive to nothing,so that after login to the same account nothing happens and the start menu does not come. However I had the ctrl+alt+del available and I could call the regedit from it. I checked all the tweaks and they were there incl. the wallpaper setting.

Remember I was logged in, but the shell was not running.

I used a modified regtweak.reg for that

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]

"WallpaperStyle"="2"

"UIHost"=hex(2):43,00,3a,00,5c,00,69,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,73,\
 00,5c,00,63,00,75,00,73,00,74,00,6f,00,6d,00,55,00,49,00,5c,00,63,00,75,00,\
 73,00,74,00,6f,00,6d,00,75,00,69,00,2e,00,65,00,78,00,65,00,00,00
"Shell"=""

After I switched the explorer hive back to explorer.exe and relogged to the same account as before...the account logon went on sucesfully and I got the start menu and everything. But the wallpaper setings went away and were reset to that bliss.jpg again.

What is wrong pls..?

My sugestion is that those HKCU tweaks ARE applied but right after the first logon the are overwritten back to default settings.
