This is possibly a bug: The Service Manager doesn't seem to be able to Enable services that are Disabled. The opposite, disabling services that are either Automatic or Manual works fine, but then when I try to turn around and re-enable the service, it doesn't work. It refreshes the screen as it if had worked, but the service remains disabled.
Additionally, when clicking "Enable" on a service that is Disabled, the notes at the bottom make it seem as if jv16 PowerTools is still disabling the service.
For example, I right-click on ClipBook (which is Disabled), choose "Enable" from the menu, the screen refreshes, ClipBook is still Disabled, and the notes at the bottom say : ClipBook has been disabled.
