Fixed
- RestartExplorer could leave the user without a taskbar/desktop if any explorer.exe process was unkillable (e.g. elevated or another user's session). The kill loop and the shell relaunch lived in a single try block, so one Win32Exception from Kill() on a higher-integrity explorer aborted the entire method — explorer was dead but never relaunched. Each process is now killed in its own guarded block (matching FileLockService.KillProcess's per-process pattern), and the Process.Start("explorer.exe") relaunch runs unconditionally after the loop so the shell is always restored.
- The Context Menu tab's "Enable" action on HKLM-disabled entries reported success but actually did nothing. The HKCU fallback path used CreateSubKey even when enabling (removing LegacyDisable), which created an empty orphan key and deleted a value that never existed there, then returned true. The HKLM LegacyDisable was never touched, so Explorer still hid the entry and the next scan snapped the toggle back. The enable path now uses OpenSubKey and returns false if no user-authored override exists to clear — surfacing the "needs admin" message instead of silently lying.
- Every Context Menu toggle froze the UI thread for up to 5 seconds. ToggleEntry was synchronous and called BackupRegistry which spawns reg.exe with a 5-second WaitForExit — all on the dispatcher thread. Converted to an async command with Task.Run, matching the existing ApplyPresetAsync pattern that already offloads the same service calls for exactly this reason.
