Windows XP: Cannot change XP desktop

Windows xp: Cannot change XP Desktop

Be sure to scan the computer for malware as it frequently causes this type of issue, but there are registry problems, caused by malware, which can be fixed once the virus/spyware is removed. Since you are using XP HOME, you don't have the Group Policy Editory to use but try editing the registry entry below to get the display option to function again. I believe the Group Policy Editor changes the registry key below to alter the "Remove display in control panel". If you find the key as specified below, you should be able to modify the dword to "0" which would then cause your display panel to appear and work correctly.:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"NoDispCPL"=dword:00000001
