Fregonator

What Fregonator is

Fregonator is a free, open-source utility for cleaning Windows system files and performing maintenance. It supports Windows 10 and 11, and its free plan is free. The utility removes temporary files, system caches, and recycle-bin contents, and can free RAM. Its Basic, Advanced, and Ultra modes offer different cleanup options; Ultra also updates apps using winget. Other tools include startup management, driver updates, scheduled maintenance, SSD TRIM, boot optimization, and parallel cleanup tasks. Built-in DISM and SFC are available for additional maintenance. Fregonator also offers selective bloatware removal, naming Candy Crush and Bing apps as examples while saying it preserves apps such as Spotify and Netflix. The site says an automatic restore point is created before cleanup, and that the app does not alter registry or browser data. Its FAQ says Fregonator has no telemetry, internet connections, or tracking. The source is available on GitHub under the MIT license. Basic cleanup does not require administrator permissions, but advanced tasks such as DISM, SFC, and bloatware removal do. Installation is listed through a PowerShell command or the winget package DTHCST.Fregonator; PowerShell 5.1 is required and the site says it is included with both supported Windows versions.
