Microsoft....
Something like this is very common for a user to right click and tell the system to open something with a certain program. It should never override ALL the shortcuts on a desktop....really and you guys are professionals up there? What are you thinking anyway?
This should never EVER happen other than to the ONE and ONLY file that was being instructed to be opened by whatever program that was selected not ALL the shortcuts.
I thought they had a drug testing policy for corporate jobs like the one you guys have....geez.
And the suggestion that the engineer here gave is not what will solve the issue, only that tool that was linked in here a couple times will do it or you can manually do it yourself.
Bad service, bad design and then to turn around and try to get people to believe it's something they did on their end and they made the "mistake" when you should've had this product set up from jump to NOT allow something like that to happen. Your mistake your
bad design, it's all on YOUR end. FIx it.
