I've just been updating my irregularly used Win10 laptop, ready for a trip out - to avoid it cobbling up mobile data to carry out it's updates. It proved to be a fairly major update... When it finished, during the reboot, it demanded my Microsoft account password, and no way I could find to bypass needing the password. I normally keep those passwords in an encrypted file on the computer, but no way to access that until it had booted. Luckily, I was able to produce the password, via my main laptop, but had I not been at home, with access to it...
. Most disk/file encryption can be hacked, unless you pay for industry standard security, of course.
