Unencrypted data (no bitlocker) can be always accessed, the hacker does not even have to bypass the account, he can pull out the disk. But MS account can not be abused or accessed this easily, so I would not worry about it, just keep sensitive data protected/encrypted.

And this kon boot site looks dubious (at best), I'm certainly not going to click the link

I risked having a look in a Private Browsing window, seems it's paid for software. If you want a safer way to see what it's all about, they have a Youtube video.

There is also a Wikipedia article that explains how it works, and its limitations. Disk encryption would seem the best way to defeat it.
software as Kon-Boot is not able to bypass disk encryption.[24] BIOS password and enabled SecureBoot[25][26] feature is also a good prevention measure. However Kon-Boot since version 3.5 is able to bypass SecureBoot feature.[27] Kon-Boot does not support virtualization and instructs users to turn it off in the bios.[28] Kon-Boot does not support ARM devices such as Apple's M1 chip.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.
