AdGuard For Windows Release Notes

Hotfix

In this hotfix, we’re automatically migrating all users from the outdated TDI driver to the more reliable WFP driver. This change comes as a solution to an issue reported by users, ensuring filtering works with the latest versions of Chrome-based browsers, which aren’t fully compatible with TDI.

TDI isn’t going away completely — you can still enable it if you want to. But if you do, the app will show you a clear warning explaining the potential issues and how to temporarily fix them. For all the details, check out our Knowledge Base.

Improved userscript compatibility

This update brings exciting improvements to make your AdGuard experience even better: you now get more customization with our improved userscript compatibility. Behind this change is CoreLibs v1.19, AdGuard’s filtering engine and technical core. Although not strictly tied to this release, we also have something worth celebrating: AdGuard is now available in the Microsoft Store, making installation more convenient and, we dare say, easier than ever.

Some userscripts are designed to work on Single Page Applications (SPAs), such as YouTube. Until now, these scripts often failed to load correctly: if a user opened YouTube’s homepage first, the script wouldn’t inject, and it wouldn’t trigger when navigating to other pages where it was supposed to work. With this update, AdGuard fixes that limitation by ensuring such scripts are properly executed across SPA websites, making AdGuard even more flexible for advanced customization options. This enhancement also allows us to confidently recommend useful tools like the SponsorBlock userscript, which automatically skips sponsored segments in YouTube videos. To try it out:

• Go to https://mchangrh.github.io/sb.js/.
• Click Generate link.
• Copy the link that appears.
• Open AdGuard and go to Extensions → Add extension → Import from file or URL.
• Paste the copied link and confirm.

AdGuard is now in the Microsoft Store

You can now download AdGuard directly from the Microsoft Store, making it quick and secure to install, update, and manage alongside your other apps. Subscriptions and payments are still handled directly through AdGuard’s website, ensuring flexibility and full control over your license. Product updates for builds downloaded from the Microsoft Store will work the same way as in the regular builds. In other words, the store version is simply a new distribution channel, and the update process remains unchanged.

Support for Comet browser

We’ve added full compatibility for Perplexity’s Comet browser. Now you can now enjoy the same reliable ad blocking and privacy protection in Comet as you do in other supported browsers.

Along with the usual bug fixes, this version brings something new for those using Microsoft’s latest Copilot+ PCs. The Tracking protection section in AdGuard for Windows now includes an option Disable Windows Recall. Why is it needed?

This feature blocks Recall, a tool that periodically takes screenshots and stores them locally, so you can search through your past activity like a timeline.
Microsoft claims it’s private enough: it’s off by default, requires Windows Hello authentication, avoids collecting sensitive data like credit card numbers or ID documents, and encrypts all stored data.
But for AdGuard, that’s not enough. Screenshots still capture what’s on your screen — and not everything that’s private can be reliably filtered out. For example, a chat window, a partial account number, or something as simple as your to-do list could be saved without your knowing.
While Copilot+ PCs are still new and not widely used yet, they’ll likely become the new norm soon enough. AdGuard is ready to protect your privacy even before that happens.
To stop Windows from capturing your screen activity, open Settings and enable Tracking Protection — Disable Windows Recall will be enabled automatically.
