Windows 10 seems to be one huge example of this. It's a travesty of an OS. Below are some of the things which it does to make me want to chuck the entire computer out of a window:

- Overlay the huge "you need some updates" panel, with no option to close the window. Every key input brings you to the update installer.

- Windows Defender frequently ignores my exclude lists, which causes it to start scanning my VM's .vmem files, reading and writing several megs per second to disk, causing my VM to be unresponsive for 20+ minutes if I do not restart my entire system.

- The new search options in the task bar seem to have gotten worse since Windows 7. Whenever I start typing something like 'not', it shows me Notepad++. When I then add the 'e', the options disappears.

- Lately, my Windows 10 has decided whenever I boot up a system, it should restart all processes that were active when I shut it down before I have had time to even log in, which is kind of a fucking bother when I had loud music playing in the background when I shut it down.

- All the goddamn bloatware on it. I know that when I buy a DELL or HP, I'll have to completely reinstall the system to get rid of the bloatware, but Win10 comes with its own set of it for some reason.

- All the 'smooth' animations, which slow the UX just enough to be frustrating. Don't slowly slide up the start menu, just pop it into place!
