I am now ready to install SP1 on Vista HP 32b. What would be the best way to proceed?

You can grab the d/ from here...
Download details: Windows Vista Service Pack 1 Five Language Standalone (KB936330)
I suggest the following:
1. make sure you have the prerequisite KBs installed. Those are:
KB 935509 Bitlocker Update (Enterprise and Ultimate editions only)
KB 937287 Servicing Stack Update
KB 938371 Reliability Update
2. Download SP1 and SAVE it.
3. Unplug all devices (e.g. printer, external disk, etc.) except mouse and keyboard.
4. Install in Safe Mode - that avoids any conflicts with running processes.
5. When finished, plug devices back in.

You must install SP1 before you can install SP2.
Thank You All...I did both SP 1 & 2. All appeared OK. We'll see.....

Good job. Should have greater stability.
