    Hyper V

    Yesterday I decided to see if Hyper V worked on my windows 10 pro (build 10240).

    Having never used it before i looked on the internet for it and eventually found out that it is included in windows 10 and that I didnt need to download it. Well I think I dont need to download it. Anyway I found out I needed to go to the Windows Features section in the add/remove programs to enable it. I opened the Windows Features, found the feature I wanted to enable, screenshot attached. I enable Hyper V Management Tools, The progress indicator (green progress bar) said it was applying my changes, then I thought that this is strange because it didnt ask me to restart - I remember from other times Ive used it, I have always had to restart (Ive never used it in windows 10 but in other operating systems). I also thought that the option for Hyper V platform is probably the one that I needed so I enabled that one, it would not let me click in the box next to hyper v platform, I had to first open the option with the + sign but I could only choose Hyper V Services and not Hyper V Hypervisor because it was greyed out.(?) I though that strange because it seemed like the Hyper V virtual machine was what I needed. After I clicked the green bar returned and then I was asked to restart my pc. I let it restart and went away from my laptop for a few minutes. When I came back the laptop screen was black and there was a mouse pointer on it. I waited a while and then when nothing happened for about 10 minutes I pressed CTRL ALT DEL (hoping that it would work), all of a sudden the screen came alive (no text in the centre) with the spinning balls. This lasted a few minutes and then the screen went black again, I waited about 5 minutes and then pressed CTRL ALT DEL again, again the spinning dots and then blackness, I pulled my laptop battery out and started the laptop with the power button. It r\took a few minutes, saying something about enabling features, during this time I decided that I was going to turn off the Hyper V options I had chosen. When I had logged in I went to the windows features and unenabled Hyper V and then restarted, The computer started normally after enabling (disabling I assume) features.

    Tonight I switched on my laptop and got a BSOD caused by DPC WATCHDOG VIOLATION - I looked it up on the internet and it seems that it is to do with fast start up, the article I found said to disable fast start up but I left it enabled because I dont remember an issue with DPC WATCHDOG VIOLATION ever happening before.

    On a side note - Im on the slow ring for insider builds, currently on 10240, when is a new build going to happen for us slow ring users?

    My HP desktop doesn't seem to support hyper-v in UEFI even though I have VTx enabled in the BIOS
