I run a Virtual PC with Vista 32-bit as Guest operating system for my software development purposes. This VPC is quite slow despite taking measures to shut down various background services.
For reasons beyond my understanding (and me not willing to investigate on it), whenever a MMC console window is opened, CPU usage spikes to 100%. It was frustrating to to start SQL Server Engine by going to the services.msc console. So, I found a way to start SQL Server service from command line.
Please click on above image to see the command in clarity.
