Hyper-V was enabled, but disappeared

Hello

I enabled Hyper-V on my computer. When it restared I saw it was configuring Hyper-V. I didn't opened Hyper-V the same day. Two days later, I wont to open Hyper-V but I can't find it anywhere! Also, it isn't listed in programs anymore... I also enabled virtualisation in the BIOS.

Check that both Hyper-V boxes are ticked in Windows Features... I can't install it on my current PC as it is too old.

Do you have Windows 8.1 Pro? If you do you should have it, if you don't well it is time for a software upgrade
