Restart and Configure WSL2 Default

Restart Windows

Section titled “Restart Windows”

A restart is required after enabling the features above. The features are not active until the system reboots.

Option A — from PowerShell:

Terminal window
Restart-Computer

Option B — manually: Start menu → Power → Restart

Before continuing: Log back into Windows and wait until the desktop is fully loaded. Do not proceed until the restart is complete.

Set WSL2 as Default Version

Section titled “Set WSL2 as Default Version”

After the restart, open PowerShell as Administrator again and run:

Terminal window
wsl --set-default-version 2

Expected: For information on key differences with WSL 2 please visit... followed by confirmation, or no error.

Verify immediately:

Terminal window
wsl --status

Expected output includes: Default Version: 2

If prompted to update WSL: Run wsl --update (only when Windows shows the update message), restart if asked, then re-run wsl --set-default-version 2.

If you see a kernel component message: Run wsl --update first. If that does not resolve it, install the fallback package from https://aka.ms/wsl2kernel, then re-run the command above.
