My right-out-of-warranty Logitech M590 mouse lost its pairing to its USB-receiver upon booting up Windows after using the mouse in Linux for weeks out-of-warranty. I bought another one, and that too did the same the first time I booted up Windows after the warranty had expired.

Finally I searched the issue, and it's normal. I had to install a non-default Logitech software in Windows and re-pair the apparently broken mice to their receivers. Both mice work again, except the older one's left button is acting up a bit.

A non-asshole company would have notified me "Your mouse receiver needs an update that requires re-pairing the connection manually. Do you want to continue the update?". And why the hell would a mouse receiver need an update when the warranty ends?

Obviously the purpose is to make the mouse appear broken with plausible deniability and bluff the customer into buying a new mouse.

This is known as programmed obsolescence.
