No more taskbar transparency, can't rearrange order of email addresses in Mail, can't insert files to the start menu like a quick note text file or to-do list, doesn't automatically connect to wifi for me despite having certain wifi set that way, can't turn off windows update or defender despite desperately needing battery power on my laptop. Before i learned how to disable it, i would find Windows Update running in the background while my wifi was off and while in airplane mode and also while on "metered connections". Oh, you have to change each connection to metered to prevent update from hammering fragile public wifi spots. I once found update having stealth downloaded in the background a massive 300mb update it on a metered connection and i had been having trouble connecting to the internet at that wifi all morning. WTF. Which means everyone else at the busy coffee shop probably did too, because of me.
So many little deficiencies and issues for me. As i no longer appreciate the new start menu and prefer the "pinned" programs list in the Win7 start menu, i believe THE ONLY thing about 10 i like is the more battery efficient media player, which is fucking horrible beyond that. I highly encourage everyone who reads this to be punishingly careful in your future microrsoft purchases. This is not the passionate Bill Gates Microsoft anymore i don't believe. This is the lets make sure we pry as much money from our fellow citizens as possible and give as little as possible typical "business". They want to play hardball to the point of being immoral and parasitic, play hardball then...
