The Windows Club has released Ultimate Windows Tweaker 4.0 for Windows 10 users. The lightweight, portable freeware tool makes it easy to tweak various aspects of Windows that usually hidden away or require access to Registry editor or Group Policy Editor.

The new release sits alongside the previous versions, Ultimate Windows Tweaker 3.1.2 for Windows 8/8/1 and Ultimate Windows Tweaker 2.2, which requires Windows Vista or 7.

The latest build of Ultimate Windows Tweaker now ships with over 200 tweaks, an increase of around 20% on the previous Windows 8.1 release. Like its predecessors, it’s a portable tool (so requires no installation), and ships in a small 549KB zip archive.

The latest version of Ultimate Windows Tweaker provides over 200 tweaks for Windows 10 users.

Again, the app has been redesigned to fit in with the Windows 10 user interface, with new tweaks added, and existing ones updated or removed if no longer relevant. An additional category of tweaks has been added too, with a whole section devoted to the desktop context menu, allowing users to add their choice of additional options (including modern and built-in apps, as well as system tweaks) to the right-click menu.

Two new tabs also replace the “Additional” tab found in the previous version’s Customization section: Windows 10 and This PC. The latter makes it possible for users to add shortcuts that appear when in This PC view in File Explorer, while Windows 10 contains a series of OS-specific tweaks focussed around performance and its look and feel.

The first time users launch the tool, a SmartScreen security dialog may pop up – users should click for additional options and choose to “Run anyway”. The app will now launch, and the SmartScreen dialog won’t appear in future.

Ultimate Windows Tweaker 4.0 is available now as a freeware download for Windows 10 users.
