As mentioned by continuum, this is not possible from the Hypervisor. However, you may want to check whether the Windows guest itself contains System Restore Points to which you may be able to revert.
In any case, I strongly recommend that you create a virtual machine snapshot prior to trying things, so that you are able to revert at least to the current state.

You can not go back to a previous state unless you created a snapshot at that time.
The guy who invents such a function will be a rich man soon

also check if you have any backup solution , which is protecting server in different way either agent or VM
If you have backup solution, Like Veem backup then we can do recover complete virtual machine.
