Windows: Whether you need to reset the Windows Services configuration back to stock after your over-zealous friend started modifying his computer or you'd like to make a pre-configured registry file for that friend, ServicesEditor makes configuration tweaking easy.
Years ago we saw how to edit which Windows services are running on your computer to increase performance. What if, after a configuration-tweaking session gone wrong you want to reset everything to the default?
You can hop over to ServicesEditor and check out the default configurations for Windows XP, Vista and 7. Not only can you see the default configuration but the list is interactive. You can toggle items to manual, automatic or disabled, and then when you're done, download a .REG file that will make the changes to your system registry on your behalf.
An application you may be interested in, if you're doing a fair amount of services tweaking, is previously reviewed Services Profiles which allows you to create custom service profiles for various tasks like gaming. ServicesEditor is a free, web-based, service.
