W11 Optimiser
A safe Windows 11 optimiser with two ways to run it: one PowerShell command, or a downloadable ZIP with a double-click launcher. The PowerShell method checks the downloaded script SHA-256 before opening the menu. Nothing applies until the menu asks for confirmation.
PowerShell Method
Run From PowerShell
Open a normal Windows PowerShell window, paste this command, then press Enter. Approve UAC with the same Windows account when prompted. The command downloads the latest optimiser and opens the menu.

Improvements In Version 1.1
Original Plan Stays Untouched
Each safe run creates its own temporary W11 Optimiser power plan. Undo returns to the original plan and removes the temporary one.
Backup Before Change
If an existing registry key cannot be backed up, the run stops before it changes any settings.
Checked Download
The PowerShell method checks the downloaded script SHA-256 against the published release manifest before the menu opens.
Focused Undo
Undo restores only the values this tool changed. It does not recursively delete whole registry paths.
What Happens After A Run
Local Report
Safe runs create a local browser report. It shows what changed, what was skipped, what was not touched, warnings, errors, and next steps.
No Uploads
The report is generated on the PC and opens from a local file. The demo page below is sanitized, so it does not include any real computer name, username, folder path, or adapter details.
