Which Windows versions does Winaero Tweaker support and is this its official site?

Winaero Tweaker supports Windows 11, Windows 10, Windows 8, and Windows 7, and winaerotweaker.com is the app's official site. The page describes itself as "a new home for the app," lists the latest version as 1.65, and identifies the tool as freeware created by Sergey Tkachenko. If you are on one of those four Windows versions, this is the right place to get the app and check its current release.

Supported Windows versions

The site's own description covers four generations of Windows:

The site does not break support down further—for example, it does not state separate requirements for 32-bit versus 64-bit builds or for specific Windows 11 feature updates. For that level of detail, the site points readers to its release notes and FAQ rather than the main page.

Is winaerotweaker.com the official site?

Yes, based on the page itself. Several details support this:

• The page calls itself "a new home for the app," indicating the site is the app's current official location rather than a mirror or download aggregator.
• It names the author directly: "a freeware app created by myself, Sergey Tkachenko."
• It hosts the materials an official project site would normally host: release notes, an FAQ, version history, screenshots, a blog, announcements, and license information.
• The site states it is "ads-free, scripts-free, and web tracking-free," and the app is described as having "No telemetry/spyware/ads."

That last point matters if you found the download through a search engine or a third-party software directory. The official page is the safer source, since it is the one that publishes the version number and release notes you can check against what you downloaded.

What to check before and after downloading

1. Confirm your Windows version via Settings > System > About. If it is 11, 10, 8, or 7, the app is listed as supported.
2. Download from the "Get the app" section of winaerotweaker.com. The page shows the current version (1.65 at the time of the site content) next to the download link.
3. Compare the version you received with the number on the site and with the release notes page. A mismatch suggests you got an older build or a file from somewhere else.
4. If the app does not start, the site has a dedicated troubleshooting pointer ("App doesn't start? See this") rather than leaving you to guess.

Common sticking points

• Older or newer Windows builds: The page lists Windows 7 through 11 but does not promise support for Windows Server editions or for Windows versions outside that range. If you are on something else, check the FAQ before assuming it works.
• Feature availability by version: The app bundles dozens of tweaks, and some—such as Windows 11-specific appearance options—may behave differently depending on the OS. The feature list describes what the app can do, not a per-version compatibility matrix, so verify individual tweaks against the release notes if one seems missing.
• Trusting the download source: Because the app is freeware with no ads or telemetry, copies circulating on other sites add nothing and may differ from the official build. Use the official page and its version number as your reference point.

For anything beyond the four supported versions—specific build requirements, known issues, or changes in 1.65—the release notes and FAQ linked from the official page are the places the site itself directs you to.
