Vista - Vista, Vista we know you are just born but...

Hello,

I am on a Small Business Server Premium Edition Domain/Network. currently
have one machine running Windows Vista Business Edition. The issues I am
having are:

Windows Fax and Scan keeps crashing when I open it. I removed the fax
modems, including the one for the SBS server, removed the fax client for
SBS. Uninstalled & Reinstalled Windows Fax and Scan and the error persists.

***I cannot add items to the internet explorer favorites. Keep getting
"Access denied error messages" ---- ok fixed this one added my username to
to the security settings for the favorites folder and uncheck the read only
check box.

I cannot install Business Contact Manager for Outlook. Machine restarts
during the install.

I also cannot install Microsoft Office Account 2007. Machine also restarts
during the install.

How do I resolve these issues?

Thank you for your insights.
