Dp has his own office with his own computer, all up to date with Windows 10. I have used it on the odd occasion and made it very clear I am not a fan of windows 10.
We also have a family laptop that I use for work and the children use for homework. He uses it sometimes for quick things but not much.
He has warned me
today that he will be updating the family laptop to windows 10 after Christmas. Apparently this is non-negotiable 
Both myself and the dc have made it clear that we don't want this for various reasons. I am not a fan in general and one of Dd's programs doesn't run well on it (she's tried it on his computer).
AIBU to not want him to do this? Maybe it's just the stress of preparing for Christmas that's making me blow this out of proportion. I know It's petty but I hate being told he is just going to do it without discussion.
Anyone had any problems with windows 10? Maybe if I have some examples he'll listen to me a bit more!
