If you cannot change Security settings or the Security settings page is grayed out in Hyper-V, here are some simple solutions to get the options back. This page can show an error message saying Some settings cannot be modified because the virtual machine was in the following state when the window was opened: running. If you are getting any such message, here is how you can get rid of it and make all options visible.
The entire message error message saying something like this:
Some settings cannot be modified because the virtual machine was in the following state when the window was opened: running. To modify a setting that is unavailable, shut down the virtual machine and then reopen this window.
If Security settings are grayed out or you see Some settings cannot be modified message in Hyper-V, then use these methods to change them:
- Shut down the running virtual machine
- Stop background processes
If you read the error message minutely, you may find the solution there itself. You have to shut down the virtual machine before changing these settings. However, at times, you might not be able to shut down a virtual machine and instead get some other errors. On the other hand, Hyper-V’s Security settings page might be grayed out even if no virtual machine is running. In such situations, you need to stop all the background processes.
