Windows 10 is also very un-customizable compared to XP, which basically blasted the door open on UI skinning. You had many options available if Luna or Windows Classic didn't suit your tastes (even a few direct from MS).
Even if you manage to restore some sanity to the look of 10, an update comes along and wrecks your hard work, as well as altering many of your settings, crushing your anti-telemetry safeguards and rearranging the UI like the chairs on the deck of the Titanic.
