Another thing to watch out for is fake third-party utilities that will claim they will fix this problem. Unless directly provided from an official Distro itself and is verified, be careful what you download and install.
This is a golden opportunity for malicious actors to get bad code into systems.
If it’s never seen Windows you may be fine.
The problem is mostly for systems that dual-boot or had Windows at one point, but got Linux installed on top. A lot of people use old Lenovo, HP, or Dell computers and repurpose them for Linux. Those are the ones that may get bit.
The Windows update loads a chain of trust that tells the bootloader the device is OK and your version of Windows is real and your full-disk-encryption is fine. Linux folks don’t have (or need) all that. They can create their own chain of trust if they want, but they don’t have read/write access to the Microsoft one.
If they did, we would be reading a completely different article starting with why the world was on fire.
If you start with a reasonably recent Windows machine, there’s a TPM with secure boot (and MS keys) enabled. If setting up dualboot Windows/Linux, you’re going through BIOS/UEFI, so expiring keys will affect you. Booting into Windows and doing an update should fix the problem.
If you disabled secureboot/FDE, then installed Linux and left it at that, you should be OK.
But under Linux, those who reenable fulldisk encryption or secure boot via the TPM may be impacted by this, and since they’ve removed Windows, they may be screwed: https://allthings.how/how-to-enable-tpm-encryption-and-secure-boot-on-ubuntu-24-04/

A while back I used one of these Ubertooth Ones: https://greatscottgadgets.com/ubertoothone/
It could measure and plot signal in the 2.4G spectrum for both Bluetooth and WiFi. One time, my wife tossed a burrito in the microwave. The spectrum chart went nuts. White noise.
Unless microwave shielding has greatly changed, there’s a lot of leakage. You’re better off getting one of those shield pouches off Amazon or AliExpress.
