Which context menu item broke my task scheduler & event viewer?

I get a "mmc could not load snap-in" error for those after using Windows 10 Manager's Context Menu manager to clean up my context menu.

I disabled about a dozen items and didnt notice it broke anything until after a restart.

I tried to backtrack my steps and had little luck so i simply re enabled everything. The problem is at that point even after re enabling them all and restarting, task scheduler etc stay broken.

Any idea which items in the context menu would be linked to something like that and why after re enabling said item it doesnt fix the issue?

Ive dug through tons of microsoft forum posts, messed with registry settings, re installed .nets etc.

I went ahead and did a restore which managed to mess up my dropbox pretty good (didnt consider that angle as dropbox runs at windows start for me) and id like to deter and further havoc.

The ideal result would be to return to the latest restore point where everything would be as it should EXCEPT my dropbox (hopefully fixable) and the choice mmc snap-ins (assuming i can find out why they arent starting/working properly)

Anyone able to offer anything I may not have ran across on google?

I figured it out!

Disabling the Send-To menu does it. NOw the more important question is how to fix it? considering re checking the box to enable send-to again doesnt seem to revert the behavior. what is not getting "turned back on?"

Just to be clear, re enabling the send-to context menu item does return send-to to the context menu, however it does not revert my broken snap-ins to functioning.

For anyone with a similar issue in the future.

It seems modifying anything related to the send to menu (doesnt have to be removal of the send-to menu itself, but evne using context menu manager to modify (aka disable) any of the items under it (things like bluetooth ill never use on my desktop for example) will break the mmc snap-ins.

The only way to do it without breakage is simply deleting the shortcuts in shell:sendto folder. The tie-in/relation via mmc and the other method or the menu itself is above my pay grade :P
