I found these fake Microsoft support popups just yesterday, so hopefully they should still work.
I would have uploaded them sooner, but the site was down for a good bit of yesterday.
1 (844) 395-6205
1 (866) 937-0917
1 (888) 410-7034
1 (833) 642-3637
1 (877) 475-6758
1 (844) 395-5624
1 (833) 642-4412
1 (833) 642-3840
Some of these numbers are very similar, so I suspect many of them lead to the same call center.
From now on, I'll be posting links, and uploading screenshots as well, so enjoy!
