1) Message boards : Windows : Getting 32 bit tasks instead of 64 bit from time to time. (Message 22540)
Posted 589 days ago by Super Nova Nerd
I have been getting 32 bit tasks every so often instead of 64 bit. I am not sure why or how to stop it. They take twice as long to do. I am running Windows 10 on a 64 bit system. If I look at the canonical result on long tasks I see this -

On the correct, shorter tasks I see this-
