Hello, This is a solution for anyone interested. While I was studying for my Server 2012 R2 exam I noticed I was having trouble installing hyper-v on my machine. I had the original operating system 8.1 Basic installed. In order to have hyper v as a feature you will need 8.1 Pro or enterprise. 

Once you go into programs and click programs and features, click turn windows feature on or off. Then click hyper v and click o k and close. My installation would go to 30% restart then go to 98% and undo changes. I tried installing just the hyper v manager and then going back to hyper v platform. I installed hyper v manager with no issues but when I went to add a server it would show my machine in the list with a red X. 

There was nothing wrong with my hardware and Visualization was enabled in the BIOS. 

I updated the BIOS firmware, installed 4 extra GB of memory, changed the Hey local machine max filters, ran all windows updates and optional updates, and still no Hyper v platform. I also tried installing using power shell and I had no success. I disabled my Kapersky anti-virus and then uninstalled it from the machine. I was then able to run hyper v platform and create a virtual machine. Not sure why Kapersky blocks hyper v platform but I now have my lab environment running. I also checked the log files to see if kapersky was to blame but there were no mention of Kapersky blocking visualization. 

I believe this is an issue with Kapersky but might be a deeper problem. 

Its Kapersky.  Do you have the latest version?  A lot of AV vendors have issues with virtualization software.

It could also be something enabled on Kapersky for blue pill threats.

Hi,

Please check if there is any error message in the right pane?
