FAQ

Will it break my existing setup?

No. The installer backs up your current profile as $PROFILE.bak.<timestamp>. Restore anytime:

Copy-Item (Get-ChildItem "$PROFILE.bak.*" | Sort-Object LastWriteTime -Descending | Select-Object -First 1) $PROFILE -Force

Does it work with PowerShell 7 (pwsh)?

Designed for PowerShell 5.1 (Windows built-in). PS7 uses a different $PROFILE path — copy the file there manually if needed. Some WMI calls may need adjustment.

How do I update LyonShell?

Run the install one-liner again. It creates a fresh backup each time.

BIOS/GPU update tags don't appear?

Update checks need internet access. Results cache for 24 hours in %TEMP%. If no update exists, no tag is shown (zero false positives). Currently supports NVIDIA GPUs and ASRock motherboards for update detection.

Can I use a custom name in the prompt?

Yes — edit $LyonShell.Username at the top of your profile:

$LyonShell = @{
    Username = "hacker"
    ...
}

---

Uninstall

Remove-Item $PROFILE
# Or restore your backup:
Copy-Item (Get-ChildItem "$PROFILE.bak.*" | Sort-Object LastWriteTime -Descending | Select-Object -First 1) $PROFILE -Force
