Microsoft never has recovered from their dismantling of their test organizations.
I've also have an issue where sometimes the start menu doesn't let me type in the search on the first open until I close and reopen again.
I swear it basically always misses the first key I press if I haven't typed in a while. Sure, it could be the keyboard going to sleep to save power or whatever.
But that same keyboard never had any kind of issue on my other computers, including under Windows, nor on that very same computer running Linux.
I have seen it across multiple machines, different keyboards, different video cards. Super annoying, but at least it is consistent so I can get used to it...
