What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Try a graceful shutdown first: Stop-VM -Name "<VMName>" asks the guest operating system to shut down cleanly. If that does not work, choose a forced shutdown or abrupt power-off only after considering possible data loss. A VM stuck in a Hyper-V state such as Starting or Stopping needs host-side troubleshooting; repeating the guest shutdown command may not resolve it.
Choose the right stop method
Run the commands in an elevated PowerShell session on the Hyper-V host, replacing <VMName> with the VM’s name. The options below are an escalation ladder, not interchangeable commands.
| Action | What it does | Data and scope considerations |
|---|---|---|
Stop-VM -Name "<VMName>" |
Requests shutdown through the guest operating system, allowing it to shut down cleanly. | First choice when the guest can respond. Microsoft documents this cmdlet for Windows Server 2025: Stop-VM. |
Stop-VM -Name "<VMName>" -Force |
Forces shutdown if the guest does not complete a normal shutdown. Microsoft says Hyper-V gives the guest five minutes to save data before forcing the shutdown. | Unsaved data may be lost. Use when a normal shutdown is ineffective and you accept that risk. Microsoft’s cmdlet reference describes this behavior. |
Stop-VM -Name "<VMName>" -TurnOff |
Turns off the VM without a clean guest shutdown. | This is equivalent to disconnecting power and can lose unsaved data. Microsoft states: “This operation is equivalent to disconnecting the power from the virtual machine, and can result in loss of unsaved data.” Reserve it for when graceful shutdown is unavailable or has failed and abrupt power-off is acceptable. Source: Stop-VM reference. |
Stop-VM -Name "<VMName>" -Save |
Saves the VM state rather than shutting down the guest. | Use only when the intended outcome is a resumable saved state and the VM and host can complete the save. |
Stop a guest that is still running but not responding
-
In elevated PowerShell on the host, request a graceful shutdown:
Stop-VM -Name "<VMName>". -
If the guest does not shut down and you accept the risk of losing unsaved data, escalate to
Stop-VM -Name "<VMName>" -Force.Quick wins for a faster PC:

If a forced shutdown does not work, or you need to turn the VM off immediately, use
Stop-VM -Name "<VMName>" -TurnOffonly if the abrupt power-off and its data-loss risk are acceptable.
Check the VM’s state in Hyper-V Manager or with Get-VM -Name "<VMName>". If it remains in a transitional state such as Stopping, use the host-side procedure below rather than repeatedly issuing guest shutdown commands.

Recover a VM stuck in Starting or Stopping
Microsoft’s Windows Server troubleshooting guidance covers transitional and other critical VM states, including Starting, Stopping, Saved-critical, Running critical, Paused, Restoring, and Online pending. First identify the affected VM and host, note any error messages, and review the system and Hyper-V logs; in a clustered deployment, also review cluster logs. See Microsoft’s Hyper-V virtual machine state troubleshooting guide.
Identify the worker process before ending it
A VM’s worker process (VMWP) is associated with its virtual machine. Use Task Manager or elevated PowerShell to find worker processes:

Get-Process | Where-Object {$_.Name -like "*vmwp*"}
Do not terminate a process until you have confirmed that its PID belongs to the affected VM. Ending the wrong worker can disrupt another workload, and terminating the correct one can still lose unsaved or transient data. Use the host-side intervention only after weighing that impact.

Check the VM’s state again. If it remains stuck after VMMS restarts, Microsoft’s troubleshooting guidance lists restarting the host as a further step. A host restart has broader impact than ending one VM worker, so plan it accordingly.
When saved state or checkpoints are involved
A checkpoint or saved-state problem can prevent a VM from functioning or starting; it is not a default remedy for every unresponsive VM. For a relevant saved-state/checkpoint issue, Microsoft’s troubleshooting guide documents this command:
Get-VMSnapshot -VMName "<VMName>" | Remove-VMSavedState
Removing saved state can lose unsaved or transient data. Use this targeted step only when the symptoms point to a saved-state or checkpoint issue, and consult the Microsoft troubleshooting guidance for the applicable Windows Server version.
Check the host or cluster if multiple VMs are affected
If VM management operations fail across several VMs, investigate the host and shared infrastructure instead of assuming each guest is independently hung. Review VMMS, storage access, network configuration, and the relevant event logs. In a failover cluster, check cluster health and resource state as well as the guest and host. Microsoft recommends cluster validation with Test-Cluster when cluster health is in question; see the Hyper-V state troubleshooting guide and Microsoft’s failover cluster validation guidance.
The cited cmdlet reference is for Windows Server 2025, while the troubleshooting guidance covers supported Windows Server versions and standalone and clustered deployments. Match process, service, and recovery steps to your Windows Server version and topology.
