OptiWin 1.0.0
The first public website release of OptiWin 1.0, a free portable Windows x64 utility by Lý Quí Chung / 56KGen. The update feed uses the three-part version 1.0.0; the application displays 1.0.
Cleanup with a preview
- Scan selected temporary files, crash dumps, thumbnail cache and Chrome, Edge or Firefox cache.
- Review counts, size and the complete file list before confirming removal; export a JSON report.
- Skip files in use, files changed since scanning and directory links. Keep directories in place.
- Older files only: at least 7 days for temporary files, dumps and thumbnails; 1 day for browser cache. Optional Prefetch cleanup considers .pf files at least 30 days old and is off by default.
- Recycle Bin, Windows Update cleanup and Delivery Optimization open the corresponding Windows tools.
53 Windows customization options
Seven groups cover Desktop, Taskbar, Start, System Tray, File Explorer, Colors and Other options. Search settings, see current values and privileges, preview changes and apply supported settings in groups. Some entries open Windows Settings instead of directly modifying a value.
Startup, performance and privacy
Review current-user and system Run entries, current-user Startup shortcuts and Task Scheduler entries. Prepare changes as drafts before saving. The shared Startup folder is not listed, and scheduled tasks do not necessarily run at startup. Drafts do not survive application exit or elevation.
Adjust supported effects, menu delay, Game DVR, HAGS and power plans. Privacy options include the advertising ID and supported diagnostic policies, with shortcuts to Windows privacy settings.
Backups and advanced tools
Back up original Registry values, inspect backups and check conflicts before supported restores. Supported startup changes and the previous power plan also have recovery records. Registry review shows evidence and separates eligible removal candidates from items requiring manual review.
Cleanup permanently deletes files. Configuration backups cannot restore them. Take Ownership records the previous owner for manual recovery and is not a recursive permission grant.
Interface and updates
English and Vietnamese. Light, dark or Windows appearance. Task progress, Stop controls, local reports and F5 refresh. The ZIP contains OptiWin/OptiWin.exe; third-party notices are embedded in the application.
Open Updates to check the public HTTPS feed. The application reads version, date, size and SHA-256 metadata, then opens the download in your browser when requested. It does not automatically download, install or verify the package.
Compatibility notes
Version 1.0 has been tested on Windows 11 x64. Options depend on Windows build, policy, hardware and drivers. HAGS requires support; Ultimate Performance may increase power use and heat. Registry or Prefetch cleanup does not guarantee a performance improvement. Compatibility with every Windows 10/11 configuration has not been verified.
