What changed
Recent versions, newest first. Every entry is a real change in this build — not marketing copy.
v11.0.1.20
Current versionSeptember 27, 2026- Fixedv11.0.1.20: trial time is persisted across app restarts and version upgrades; losing local markers no longer grants an offline trial, and a server reset is accepted only from the authenticated admin tool.
v11.0.1
September 27, 2026- NewOS auto-detection in the Tweaker — tweaks that need a different Windows version (Appx and Defender policies on Windows 7, the classic menu that only exists on Windows 11, and so on) are shown grayed out with a badge, and the backend refuses to apply them too — nothing silently "succeeds" without effect
- FixedSwitching OFF five command tweaks (hibernation, NTFS last-access timestamps, 8.3 short names, TCP autotuning, SMB1) silently did nothing — the revert command sat in the wrong slot and never ran; rollback now actually executes powercfg, fsutil and netsh restores
- FixedThe scan crash (0xC0000005 seconds after pressing Scan on Windows 10 21H2+) is fixed — the TEMP folder lookup called GetTempPath2W with swapped arguments, so Windows received the number 260 as a pointer
- FixedThe "updateTrialBanner is not defined" UI error is gone — it silently killed the bottom half of the interface script, hiding the trial progress bar and the Premium card
- FixedThe updater no longer offers to update to the already installed version — the interface version now comes from the binary itself
- ImprovedHonest "no auto-revert" labels on one-way actions (Edge uninstall, OneDrive uninstall, Microsoft Store apps) with an explanation of how to bring them back — before you switch them off, not after
- ImprovedTelemetry scheduled tasks now have a real revert — switching the tweak off re-enables all six tasks instead of only clearing an internal marker
- ImprovedThe hardware fingerprint is pinned to the last fully successful reading — the trial and license identity no longer flip between two values on the same machine
- NewInstant scan results with IndexedDB — the previous scan is cached locally, so the Cleaner page shows results immediately on launch instead of an empty page
- NewFound-files list with instant search — up to 500 junk file paths (temp + logs) are indexed in the UI and filtered as you type without rescanning; browser cache is now broken down per browser
- NewTotal-cleaned statistics — every cleanup is recorded locally (IndexedDB), the Dashboard shows all-time bytes freed and the cleanup count, resettable from the card
- ImprovedWebsite purchase resume — the store remembers your unfinished order locally and offers a one-click return to payment if the payment tab was closed
- ImprovedActivation portal remembers recently checked keys (stored only in the browser, IndexedDB) for one-click re-checks
