For those who miss what Windows looked like in 2009, Classic 7 is a heavily modified version of Windows 10 IoT LTSC, reworked to make it look as much as possible like Windows 7, while still being in support and receiving updates.<br>This has been<br>accomplished thanks to a large compilation of skins, themes, add-ons,<br>tweaks, and so on – some of which are real components from older<br>versions of Windows, adapted and modified to run on Windows 10.<br>We were not sure whether to cover Classic 7, because while it is impressive and fun, we are not at all sure it is legitimate to use. But we can see a target audience.

The good old sky-blue login screen with its decorative vine tells you that things are not what they seem

This isn't just a layer of makeup; it's more like a face transplant.<br>It includes some real binaries from Windows 7, and indeed earlier<br>versions, adapted and grafted onto Windows 10. One component is the<br>Windows Media Center from Windows XP, which was cut<br>from Windows 10 before release.

The specific version of Windows 10 that it's modified is significant.<br>It's Windows 10 IoT LTSC. We talked<br>about this specific edition in April 2025 because it's the last<br>version of Windows 10 that is still in support and receiving updates. The standard Windows 10 Enterprise LTSC release will continue to receive updates until 2027,<br>and the IoT edition, which is only available in US English, will get<br>updates until 2032 – so this is the longest-lived version of Windows 10.<br>At the bottom of our story on Windows 10 LTSC, we mentioned the<br>slightly shady world of third-party modified editions of Windows.<br>Classic 7 is one; it's a modified version of an Enterprise edition of<br>Windows, one that's only available for legitimate licensing via a Volume<br>License Agreement. Unless you have appropriate volume licensing for the underlying Windows edition and have paid the fairly hefty<br>fee, this is an unlicensed copy of Windows. So we have to spell out that<br>this is not for production use, and you should not use it in<br>any working environment. It's an interesting hack, though, and it might<br>be a bit of fun for a home gaming machine or something like that.<br>As an<br>aside, one of the most widely used tools for activating unauthorized<br>copies of Windows and Office, MassGrave, is in fact hosted<br>on GitHub. In other words, Microsoft itself is hosting tools to<br>activate unlicensed copies of Windows and Office. Whether that counts as<br>tacit approval, we wouldn't like to say.

This, unbelievably, is a Windows 10 desktop. Yes, we know it says it's Windows 7 Ultimate

Classic 7 has been under construction for over a year and a half, and<br>it's the sequel to an earlier project called Reunion7 – also hosted on GitHub, as it<br>happens.<br>As its list of<br>credits shows, Classic 7 is in part a compilation of a lot of<br>existing tools. Some of them are relatively well known, such as Winaero Tweaker, which can run on any copy of Windows and, among lots of other options, allows some of the<br>less desirable changes in the Windows UI to be undone – for instance,<br>switching to the hidden Aero Lite theme.<br>Classic 7 includes this and a lot more besides. We could identify some of the couple of dozen credited projects, such as the Aero11 theme, itself a port<br>of Aero10 to Windows<br>11. This works alongside OpenGlass, which<br>brings Aero-style transparency to Windows 10.<br>There's also the Windows NT<br>Modding Utility, and another hack that lets you change the Windows<br>version number reported on the command-line, called Custom CMD<br>Version Text. Multiple sub-components come from the Windhawk mods collection, some<br>credited to a developer called ImSwordQueen, whose themes<br>can be seen on<br>DeviantArt.

Classic 7 runs the original Windows 7 Explorer, and there's a README file on the desktop with credits

Other components are more than just cosmetic. For instance, the<br>remarkable description of Explorer7:<br>"explorer7 is a wrapper library that allows Windows 7's<br>explorer.exe to run properly on modern Windows versions,<br>aiming to resurrect the original Windows 7 shell experience." So this is not merely a theme for Windows 10 Explorer: as far as we can tell,<br>it's the real Windows 7 Explorer, but running on top of 10. The same appears to apply to Control Panel as well, thanks to the Control<br>Panel Restoration Pack. Thanks to the Windows<br>Media Center (Modern Hardware) effort, this is the real XP version,<br>which an on-screen message says replaced the Windows 8 version used in<br>an older build.
