Having decided to change some update settings in the Windows 7 Home Premium Task Scheduler in MMC I find that when I click on the Conditions tab a message pops up saying, MMC has detected an error in snap-in and will unload it.
As a result I cannot make any changes to the settings.
Relaunching the Task Scheduler does not resolve the problem. A further dialogue box says the snap-in is unavailable.
Although I can usually solve all my computer problems this one has got me beaten.
How does one replace missing snap-ins?
