I still have the 1% in pc health and registry health as well
Try rebuilding the jv16 cache:
1. Open jv16 Powertools
2. In the top menu, go to Tools>Program Maintenance
3. Click on "Flush Cache" and then "Yes"
4. Click on "Close" to close the maintenance window
5. Close jv16 and then restart it. The cache will rebuild.
That should get your registy and computer health percentages back on track.
Concerning Outlook 2007, try "fixing" Outlook.
1. First make sure that FireFox is your default browser.
2. Open Outlook 2007
3. Go to Help>Office Diagnostics and run the Diagnostics. Note that you may need your Office 2007. (If you have a folder named MSOCache on your hard drive, you will not need the CD because MSOCache will contain all files from the installation build of Office 2007.)
