The only change in SP1a is that it does not include Microsoft's Java. If you already have SP1 installed you should not use this. It's only intended for new non-SP1 installations and only if you do not want MS Java. There are no other changes or fixes.

Do not install SP1a if you already have SP1 installed!!
the only difference is that SP1 does not include Microsoft VM

yes, SP1 is better, but Microsoft had to compile to Sun Java law suite.
if you have SP1 full install keep it, cause its better

Anything attached to the name Microsoft will ultimatly get bashed even if it is a useful piece of software or a patch. Completed the download and install without problems.

ModemMan, what do you mean that you have to make sure those two dll's are registered? My installation of SP1 just canceles, and I can't run msoobe.exe. I tried to unregister and then re-register the two dll's in quiestion, but it didn't help.

Does anyone know if this makes a VLE copy a retail copy? I have read reports that it does this. I am using a real MSDN VLE copy from work on my work laptop and want to know if i can install this version? I want to make a slipstream and then reinstall however i heard reports a few weeks back that it will turn a VLE copy into a retail copy. Can anyone tell me what will happen?

Update went like a breeze on my Dell P3 733. Make sure when you use the meathod at the link below that if you have unregistered your regwizc.dll and licdll.dll files, you must reregister them in windows xp before installing SP1, otherwise it will autocancel itself out before you get a chance to install it. So far no glitches and no noticeable differences. Will investigate more tomorrow.
