Microsoft generally releases the MSRT on a monthly cadence as part of Windows Update or as a standalone tool. (For exceptions, see Skipped releases.)

The following months do not have an MSRT update:
- December 2023
- December 2024
- March 2025
- April 2025
MSE can automatically get AV updates for itself (but not through windows update) by installing Easyfix51044, details here:Right MisterEd
I already thought that Microsoft would eliminate MSRT or stop updating it (like MSE which is no longer updated via wu). Let's see what happens next month....
I presume that MSE stopped getting updates through Windows Update because MS changed something on the update servers that required anything querying for updates to be TLS 1.1/1.2 capable. Apparently Win7's Windows Update isn't. I suspect the same changes may prevent it seeing recent MSRT updates too. The most recent one that my Win7 can find today in WU is version 5.129. That was released around the same date as the last MSE definitions WU found, version 1.423.125.0.Thanks Bree,
i already used the fix and MSE update itself properly.
