    Finally, the UUPDUMP ISO 27950.1 worked correctly for updating a canary system from 27943.1 to 27950.1.
    No more errors updating and/or opening Apps from MS Store like with previous 3 uupdump Canary Builds.
    I also verified no errors after doing a clean install with uupdump ISO 27950.1

    Wonder if Canary will get anything interesting this week, or just another "nothing burger" with a "Nice set of fixes"...

    Yep. Most likely. Build 27955.1 with absolutely nothing new.
    We won't see anything different until MSFT starts shipping Krypton (29xxx.1000) builds... and that may take several months.

    Builds that showed up in the Microsoft Symbol Server:

    Windows Server LTSC vNext Build 26491.1000 (ge_prereleaseserver);
    Windows Server Annual Channel vNext (?) build 27954.1 (br_release) (Likely this week's Canary Channel Nothing Burger build...)
    Windows vNext (Krypton) builds 29452/29455.1000 (rs_prerelease).

    Hello at all, please stay on topic! This topic is not about reading the crystal ball for coming releases, it is strictly for the 27950.1 build. If you wanna do speculate, please discuss in ChitChat. Thank you.
