Interesting. It gave me no indication that it had posted, though I see without the screenshot. I did remove the "older" one from Microsoft Store after making note of my exclusions.

Question? So in order for me to become a beta tester for Malwarebytes do I have to own the product already? I've registered with them but I'm not seeing any actual download links for these beta releases they announce?

Hello @Badger

Please let the forum know if either of these helps you. With today's release, no current MB4 Beta is in effect. Also, no Beta download links are made public.

Hello @IanMosley and all:

Although the following was seen to be included for testing in the beta version, that fix is NOT presently documented in the release version:

Fixed: DNS - NSLOOKUP command not working when DNS filter enabled on Windows 11

Reference: Malwarebytes for Windows 4.5.13 Release Notes

Perhaps you could edit your post and all will be better...

It's all good and thank you.

Hello @Excursius

Even with all the unseen alpha testing that Malwarebytes' QA folk put into the consumer version of MB4, beta testing always comes with implied risks. A client beta testing system should have recent full backups and possess nothing of personal value, send/receive no email, do no banking or other financial transactions, etc.

HTH
