Q: How can I use the Windows Performance Toolkit to trace the startup performance of my machine?

A: With the Windows Performance Toolkit, you can collect detailed traces of what's happening in the OS when you run certain applications. You might want to troubleshoot, or just view, what's happening during an OS boot, and you can do that too. If you've installed the Windows Performance Toolkit, you can use the xbootmgr command to setup tracing of a Windows boot. Use xbootmgr -trace boot -traceFlags base+drivers+power+cswitch -numRuns 1 -resultPath C:\TEMP
