Problème d'espace de stockage VM Hyper-V

Hi Mric Deal ,
I am sorry for the delayed response and thank you for your patience. 

Since you have already identified and deleted the “Windows 11 environment” (~20 GB) virtual disk using Inspect Disk in Hyper‑V Manager, this confirms that the Hyper‑V VM itself has been successfully removed. 
At this stage, the remaining ~20 GB reported under Temporary files is likely no longer related to Hyper‑V, but instead due to Windows system‑managed storage (for example, Volume Shadow Copies), which are not visible in File Explorer and may not be released immediately after large disk deletion. 
For us to address the issue efficiently, could you please help proceed with the following troubleshooting actions: 

Step 1 – Check shadow copy usage 

Run the following command as Administrator and share the output: 

vssadmin list shadowstorage   

Step 2 – Scan disk usage using TreeSize (Administrator) 

Next, please use TreeSize Free to analyze disk usage and check for any hidden or system‑level allocations: 

Download and install TreeSize Free from: TreeSize Free - Download and install on Windows | Microsoft Store 

Right‑click TreeSize Free and select Run as administrator 

Select Drive C: and allow the scan to complete 

Share a screenshot of the scan results 

This will help us identify whether any hidden folders or system areas are consuming the space.
Once these checks are completed, we can advise on the appropriate next steps.

Bonjour, j'ai regardé dans le gestionnaire Hyper-V, en regardant "inspecter le disque" je suis tomber sur "environnement win 11" qui prennait 20 go a peu près que j'ai pu supprimer. Néanmoins dans mes fichiers temporaires il y a encore 20 go d'utilisé.

J'ai essayer de regarder avec votre méthode néamoins je n'ai rien trouvé de concluant. Auriez vous d'autres suggestions ?

Open File Explorer and navigate to: C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks\ or C:\ProgramData\Microsoft\Windows\Hyper-V\

Look for .vhd or .vhdx files.

Delete any files you no longer need.

Open Device Manager and

elect drive C: and click OK

Click "Clean up system files"

Check these boxes:

Temporary files

Delivery Optimization Files

Windows Update Cleanup

System error memory dump files

Thumbnails

Click OK

Go to Settings → System → Storage

Click Temporary files

Check all relevant boxes and click Remove files

Open Hyper-V Manager

Check if any VMs still exist with snapshots

Delete any remaining snapshots
