Once in "Local Security Policy", I had to go into "Local Policies" to find "User Rights Assignment", so if you're having trouble finding it, you might check that folder.
Ahhh! Thank you kindly. Sorry about that, I should have checked on the Vista box instead of on the XP Pro box.
Okay ... the key to the old iTunes issue was that there was a missing Administrators and/or SERVICE in there, so I think we've ruled that possibility out.
I think we can probably rule out the "broken Windows Modules Installer" possibility with you too. Although the poor folks with that variant of things (typically on Vista 64-bit Home Premium boxes) get a 1935 when they try to download the redistributable security update, they typically can't get
any Windows Updates to install, and their error message codes are consistently Code 0x80070424 on both the failing Windows updates and the failing iTunes installs.
For the sake of folks following this thread, here's a link to the thread where we've done the bulk of the troubleshooting work (here to date) on that particular Code 0x80070424 variation:

If you're game for more experimentation, there's a couple more things I can think of that might be worth pursuing.
The first one is operating system damage. If perhaps one or the other of those files we tried reregistering/resetting (using the Fixit) are
damaged rather than deregistered or otherwise-grumpy, then an sfc scannow may be able to help with matters.
So perhaps try running an sfc /scannow as per the following document:
[How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7|http://support.microsoft.com/kb/929833]
If the scannow reports that it can't repair any files, could you let us know what the sfcdetails.txt says about them?
If the scannow does find and repair damaged files, do you have any better luck with the updates and/or iTunes install?
