sp2 to sp1

Well I'm late with my results, but a VPC with XP-SP2 was
repaired with the original "Gold" version CD-ROM. Worked
as expected, no issues. The SP2 XP instance was slipstreamed
so no SP Uninstall or ServicePackFiles factored into the test.

Hi,

No, you will not...

I have just tested this:

Clean install using a WinXP CD with SP2 slipstreamed. Now I have a
WinXP SP2 installation where the $NtServicePackUninstall$ and
ServicePackFiles folder does NOT exist. Winver.exe reports that
Service Pack 2 is installed.

Then I use a WinXP CD with SP1 slipstreamed and do a repair install
following the instructions in step 1 to 6 that is listed he
http://www.michaelstevenstech.com/XPrepairinstall.htm

I get no error messages about incompatible service pack levels or
files, everything goes smoothly.

After the repair install is finished and the computer reboots, I have
Windows XP with Service Pack 1 installed. Winver.exe reports that
Service Pack 1 is installed, and e.g. the Security Center is gone.

Conclusion:
With a repair install, you can remove SP2 for WinXP even when SP2 was
slipstreamed into the OS install media, or if you have deleted the
$NtServicePackUninstall$ folder.
