Virtual machines can prevent exams from starting or cause disturbance during an exam, for example by being kicked out of the exam in DigiExam because of security reasons. The first step is to turn off the virtual machines that the user has turned on intendedly.
If no virtual machines have been turned on or activated by the user, it could be the built-in Windows 10 virtual machine called Hyper-V that is causing the problem. Follow these steps in order to turn off Hyper-V.
1. Hit the Windows Key and type “windows features”
2. Click on "Turn Windows features on or off".
3. When the Turn Windows features on or off dialog appears, look for Hyper-V and deselect it.
4. Click OK.
5. Restart your computer when prompted.
Now, Hyper-V should be turned off.
