Blue Screen Trying to Install Windows XP SP3

During last few months, I have been through a couple of Windows XP SP3 installation. They are mostly eventless. One of the worst was a computer that hung after reboot, but after a forced power recycle that system seem to be fine.

Just when I am about to conclude that Windows XP SP3 update is pretty good, I got the famous Blue Screen of Death.

While trying to install Windows XP SP3 on my computer, I got an "Access is denied" error message. So that was not too scary, I typed the error message along with keyword "Windows XP SP3" in Google and found an MSKB 949377 which provided a solution to this exact problem.

Now, following KB 949377, I downloaded full Windows XP SP3 package and subinacl.exe, and created Reset.CMD. But, I tried it 3 times, everytime I ran Reset.CMD, it gave me Blue Screen of Death with error message about registry access. So, I did another Google search with keywords: "windows xp sp3 access denied subinacl registry blue screen". Now "I'm feeling lucky". The first hit provides a solution that works perfectly for me. Here is link to Jason's blog post that solved my problem: http://www.mrfloppysa.com/wordpress/?p=13

The trick is to remove the HKLM line in RESET.CMD. The new RESET.CMD file would be like this:

cd /d "%ProgramFiles%\Windows Resource Kits\Tools"
REM subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
