Yes, you don’t have to worry as long as you don’t boot up windows and let it install the update.
This is not the first time they break dual boots by touching the partitions, but this is the first time they deliberately break it (that I know of). I always had windows on its own drive because of that. If you don’t use windows a lot then I would suggest to do the same. You have to change to windows through bios but it isn’t that much more work.
And just in case when installing windows on its own drive, only have the windows drive mounted so it doesn’t write to the linux drive.
