I did the same thing about the same time as you. I did boot into Windows at one point and it updated, and it absolutely fucked my system. It removed or disabled the boot loader and I think it fucked up the partition table too IIRC. I then removed everything Windows and installed another distro I wanted to try and it's been smooth sailing since, with no reason to regret removing Windows.
Edit: I was able to recover the partitions, but the Windows section of the bootloader I was never able to get working again after getting it to boot into my Linux install. That's the moment I decided to just clear out that drive and switch distros.
