That, but consider also how an application running with your user privileges has full access to the filesystem with those privileges, so it can read your entire home directory, for example. That includes your browser profile with all cookies, and all credentials that applications store there unencrypted. Not to mention how that allows for all the fingerprinting even the most nefarious marketer could wish for.

Oh, and the UAC confirmations to elevate your apps permissions to root? People will gleefully confirm them without reading what needs access anyway, so you’re golden to do whatever you want.

The security model of Windows doesn’t exist.
