The website tb.rg-adguard.net is a popular, third-party interface used primarily to generate direct download links for official Microsoft Windows and Office ISO files.
Known as "TechBench by @WZT," it acts as a wrapper for Microsoft's own TechBench servers, allowing users to access a wide variety of software versions—including older builds and specific editions—that are often difficult to find through standard Microsoft portals. Key Features & Utility
Direct Source: The tool does not host files itself; it generates a temporary link that points directly to microsoft.com servers, ensuring the downloads are authentic and untouched.
Accessibility: It bypasses the need for the Media Creation Tool, which some users find restrictive or incompatible with their current operating system.
Version History: Users can access various versions of Windows (7, 8.1, 10, 11) and Office (2016, 2019, etc.), which is vital for IT professionals needing specific builds for testing or legacy hardware. Why Users Choose It tb-rg adguard.net
While Microsoft provides official tools for current versions, tb.rg-adguard.net is favored for its simplicity and the ability to download an ISO directly to any device (including mobile or Linux) without running a Windows-only executable first. It essentially provides a "cleaner" path to the same official binaries. Is it Safe?
Because the final download URL originates from software-static.download.prss.microsoft.com or similar official domains, the files themselves are safe. However, users should always verify the SHA-1/MD5 hashes of downloaded ISOs against known official values to ensure integrity. Raycast Store: RG AdGuard Links
