Download CRY.

CRY Optimizer is a portable build for Windows 10 and 11 — no account, no telemetry. Extract the .zip and run it, or use the one-click installer. It launches non-elevated, so you can inspect everything before you grant admin.

Free and reversible. Every change is shown verbatim and a System Restore point is created before anything is applied.
