Multron Win Cleaner 1.29.3 Update

Built on .NET 10

  • No .NET runtime to install anymore. Multron Win Cleaner now runs on .NET 10 (support for .NET 8 ended in November 2026) and brings the runtime with it, so it starts on any 64-bit Windows 10 or 11 PC without installing the .NET Desktop Runtime first. The download is larger because of this.

Fixes

  • No more crash when ending an app. End Task in the Memory Cleaner widget and Performance Monitor could close Multron Win Cleaner when Windows denied access to one of the app's processes. Such apps are now listed as access denied instead.
  • Opening tools during a scan is safer. Opening Large File Finder or Duplicate File Finder no longer reloads the whole Settings window in the background, which could disturb a running scan and is the likely cause of a crash when Large File Finder was opened during a scan with Malware Scan.
  • Utilities stay usable during the malware step. While the main scan was running Malware Scan, the Firewall Rule Cleaner, Shortcut Fixer and Security Check buttons all turned into Cancel and stopped the main scan. They now work normally during the malware step.
  • Cancel tool scans from the main window. While Large File Finder or Duplicate File Finder is scanning, the main window already showed its progress, but the Scan button stayed Scan. It now turns into Cancel and stops that scan, and comes back when the tool is done.
  • No update check when updates are off. When both automatic app updates and automatic database updates are turned off, the loading screen no longer shows Checking for updates and no longer checks or downloads anything (the database is still downloaded once if it is missing).
  • Errors no longer close the app. If something unexpected goes wrong, Multron Win Cleaner shows a short message and keeps running, and the details are saved to crash.log in the program folder so the problem can be reported and fixed.

Updating

  • From 1.29.2 or earlier: the app updates itself to 1.29.3 as usual (Settings > App Updates).
  • New installs: download mwc_setup.exe (installer) or mwc.zip (portable) below.
