Biggest downside is Windows always rebooting after updates, and if I don't sit there, it boots back into Linux as it's the first option in Grub.
This is why I edited Grub to not timeout and instead wait for me to make a selection.
Can be done by running
sudo vim /etc/default/grub
Can also use nano or some other editor than vim too.
And changing GRUB_TIMEOUT=X to GRUB_TIMEOUT=-1 or a larger value to give you more time if you prefer to have it timeout eventually. -1 disables the countdown to auto select entirely.
And then run
update-grub
To have the changes confirmed.
I do this because I use Windows about half and Linux the other half so letting me make my decision works best for me.
