Question: Are there any tools to help me figure out whether my PC is up to the job?

Answer: Your first stop should be PC Pitstop’s Vista Readiness test, which runs right in your browser (Internet Explorer required) and offers a brief comparison of your system’s hardware to Vista’s minimum and recommended system requirements. Microsoft’s own Windows Vista Upgrade Advisor provides a more thorough assessment. After you download and install the program, it scans your system and prepares a report analyzing your system’s basic hardware compatibility (CPU, memory, and disk space), and detailing whether your installed applications and drivers will work with Vista.
