RESOLUTION
We have become aware of the possible issue with Parallels Desktop and Windows Vista Service Pack 1. Boot Camp VM can get broken after SP1 installation in virtual environment.
We recommend installing SP1 in native Boot Camp only.
If you have already installed SP1 in VM and now encountering problems, please repair Windows using native Boot Camp and install SP1 natively afterwards.
Note: the described above may also be true for Windows XP SP3.
