When you attempt to change your desktop wallpaper in Windows XP, the option is missing form Display Properties or is unavailable (dimmed).
The behavior can occur when you remove malware from your computer, if one or more registry Value Names are set to hide or lock display settings.
NOTE: These registry Value Names may be set by administration policy or by malicious software.
I have scripted FixDisplay.bat to resolve this problem.
The syntax for using FixDisplay.bat is:
FixDisplay
FixDisplay.bat contains:
@echo off
setlocal
call :qu>nul 2>&1
if "%OK%" EQU "Y" @echo One for more user settings were deleted.
call :qc>nul 2>&1
if "%OK%" EQU "Y" @echo One for more computer settings were deleted.
endlocal
goto :EOF
:qu
set OK=N
set key=HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System
:qboth
for /f "Tokens=1-3" %%a in ('REG QUERY %key% /V NoDispAppearancePage^|Find "REG_DWORD"^|Find "0x1"') do (
Set OK=Y
REG DELETE %key% /V NoDispAppearancePage /F
)
for /f "Tokens=1-3" %%a in ('REG QUERY %key% /V NoDispCPL^|Find "REG_DWORD"^|Find "0x1"') do (
Set OK=Y
REG DELETE %key% /V NoDispCPL /F
)
for /f "Tokens=1-3" %%a in ('REG QUERY %key% /V NoDispBackgroundPage^|Find "REG_DWORD"^|Find "0x1"') do (
Set OK=Y
REG DELETE %key% /V NoDispBackgroundPage /F
)
for /f "Tokens=1-3" %%a in ('REG QUERY %key% /V NoDispScrSavPage^|Find "REG_DWORD"^|Find "0x1"') do (

REG DELETE %key% /V NoDispScrSavPage /F
)
for /f "Tokens=1-3" %%a in ('REG QUERY %key% /V NoDispSettingsPage^|Find "REG_DWORD"^|Find "0x1"') do (
Set OK=Y
REG DELETE %key% /V NoDispSettingsPage /F
)
goto :EOF
:qc
set OK=N
set key=HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System
