Method 2: Resetting the Admin Password via PowerShell
Resetting the admin password via PowerShell is another effective method that allows you to regain access to your Hyper-V virtual machine. PowerShell is a powerful scripting language that can execute various tasks, including password resets, with just a few lines of code.
Before we proceed with the steps, it’s important to note that this method requires some knowledge of PowerShell and administrative privileges on the Hyper-V host machine.
Here are the steps to reset the admin password via PowerShell:
Step 1: Open PowerShell with administrative privileges on the Hyper-V host machine.
Step 2: Use the following command to list all the virtual machines running on the host:
Get-VM
Step 3: Identify the virtual machine for which you want to reset the admin password.

Here are the steps to reset the admin password via Hyper-V Replica:
Step 1: Open the Hyper-V Manager on the secondary Hyper-V host.
Step 2: Disable replication for the virtual machine.
