Not the case. What’s happening here is Windows is removing the ext4 partition completely, expanding the ntfs partition and writing to all of it.
Windows update did that to my <1 year old laptop. I figured it had just wiped out grub, but when it was booted from a live-usb there was no ext4 partition there at all. This has been reported many times.
Microsoft should be sued for this shit. Legal protection from destroying people’s data that is not part of Windows or in a Windows partition, whether deliberately or by negligence, is not something that can be legitimately covered by a license agreement.
Second that. I can’t think of a way that that is not deliberate. The “cover” would be that it is ensuring that the full device is used so that the end user doesn’t have to worry about it. In reality, there’s no legitimate reason for an update to touch the partition table. Way to easy to brick the system.
