Windows 10. About as secure as a Masterlock and about as well built (there's currently a Masterlock in bits in front of me in bits after I was picking it at work, it bounced around in my bike box on the way home and partially exploded... springs and spool pins everywhere.... oh and the core fell apart and the lock opened after three light strikes from my hammer).
I went to print my travel insurance docs for going away and spent more time fixing Windows' inability to manage USB devices than actually printing.
It almost got "reconfigured" with my hammer.
Do not keep a hammer next to your PC if you're using Windows 10. In fact anything which could be used to smash the PC to little itty-bitty-bits in a fit of rage should be kept away from a machine running Windows 10.
To summarise....
AAGGGGGGGGGGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!
(Grammarly says my tone is "forceful").
