Windows Vista Bld 5381 - Struggling with peripherals

I upgrade my office PC to Windows Vista build 5381 but it hasn't been a good experience so far. Maybe i should just wait for the official Beta 2 release.

Once again I choose to do a clean install instead of upgrading my XP installation. This time I had an HP Desktop available for my use.

Sound card - Vista was not able to detect and install the proper audio drivers.

Printers - Vista detected my HP Officejet 7100 printer and installed drivers for it but I am unable to print to it. Vista was unable to find my other networked printers.

Internet - IE 7 is struggling with various web pages. My own blog, for example, does not display well under IE 7 on Vista build 5381.

Foldershare - Foldershare is unable to recognize the new directory structure under Vista - c:\user\cris and it is not able to create a new directory under the My Pictures folder as an example. I have a feeling a lot of 3rd party apps will get tripped up by this.
