OpenClean shows an honest picture of your Windows PC and cleans only what you choose - temp files, caches, startup entries, duplicates and more. No fake speed boosts, no invented problems, no account, no background service, and no telemetry. Every number you see is a real measurement. Free and open source; a portable single-file build runs from a USB stick with no installation and no .NET required
What's new in 1.3.0
Added - Deep system cleanup as its own tab, covering five areas Windows keeps to itself: the previous installation (Windows.old), the component store (WinSxS), shadow copies, the Windows Update cache and the Delivery Optimization cache. Every area is measured before anything is touched and confirms separately before it deletes. - Occupied space and reclaimable space are shown as two different numbers, because they rarely match, and freed space is measured before and after instead of estimated. - Network transparency (local) as its own tab: a live view of which programs hold connections to the outside, with process name and path, remote address and port, and connection state. The view only reads - it never blocks, throttles or alters a connection, and reverse DNS lookup is off by default. - Drive health in "Storage & RAM": every physical disk gets a verdict - healthy, keep an eye on it, or failure likely - read locally from SMART through Windows, with no vendor tool and no online lookup. The verdict stays free; the individual readings (temperature, life remaining, power-on hours, power cycles, reallocated and pending sectors, total bytes written) are part of OpenClean Pro. - Real NVMe SMART values for NVMe SSDs - power-on hours, power cycles and total bytes written - decoded from the NVMe health log page, plus power cycles for USB drives. Whatever no source reports stays empty instead of being shown as zero. - A central settings area behind the gear icon in the title bar, bundling theme, language and licence management in one place. - A theme picker with Cyberpunk, Gaming-RG...
