Windows Vista Service Pack 1

Windows Vista Service Pack 1 - seems to address the following issues that were frustrating me for quite some time.

i) Windows sidebar has not been working in my machuine for a long time. It would just crash at startup and also when I try opening it from the program menu. This has been corrected and seems to be working fine so far.
ii) McAfee antivirus 2009 was getting a 'MISP Shell Error (may not be the correct error description) when I tried to open the 'McAfee Security Center'. And the Registration Wizard kept erroring out (inspite of my efforts to try to runs using various XP compatibility settings), making my calls to customer care useless as they kept telling me everytime that they cannot help without product registration. This has also worked fine for me after the update.
iii) Yahoo messenger 9.x was also erroring on the programs start up. This issue also appears to have been rectified. I was using a patched up version of Ymess 8.x until now.

Thanks Microsoft!
