So, when I am using the Windows lock screen, especially when I am not currently signed in, Windows tends to set my lock screen accent color to purple, much like my wife's account on the computer. She has chosen a purple accent color for her account, which is fine, except that mine is red. Now, this is not really a huge issue, as everything is normal once I have logged in, but the fact that everyone else's account is normal and it isn't assigning that color to any other accounts is extremely annoying. I've just been dealing with it for the past few months and I'm just tired of it.

Does anyone have any possible solutions to this? Or maybe an explanation as to why this would be happening? Thanks.
