I hope they never drop paint and notepad. Since win 95+ i've found myself still using both enough that it would really freak me out if they suddenly got deleted in an update.
Seeing someone who probably had access to use whatever Microsoft software he wanted including Word, OneNote, and whatever else they have, using Notepad, was a bit surprising and relieving.
About that first issue: both Explorer and Notepad, and probably a bunch more, insert a square instead of deleting a word when pressing ctrl+backspace. I just don't understand why Microsoft doesn't fix that kind of bullshit, and instead leave it in for decades. It's the same thing with cmd.exe; instead of improving it, they've left it in the exact same broken state since (probably before, but at least including) Windows XP, and instead of fixing the issues with it, created a whole new shell.
