Microsoft's advice has had mixed results.
Kjl1956 writing on the same answers site admitted to a successful rollback, but PaulQ_602, who detailed his machine as an Acer VN7 laptop with 256 SSD and a 1Tb HD, both using Bitlocker, hit a wall.

I had to wipe the entire SSD and start over with a clean install of Win 10 (anniversary edition unfortunately). It was freezing again soon after, but I managed to go over an hour last night with no freezing then I had to leave it. I'm going to get back on it after work and see if it's freezing again.
Windows 10 Anniversary Update freezing on some systems with SSD + HDD
