Windows 10’s super-aggressive updating tactics have just cost Microsoft some money — even if it was just a tiny bit for the software behemoth.

A travel agent in California who sued Microsoft over Windows 10 upgrades won $10,000 after an unauthorized Windows 10 upgrade ruined her computer, she claimed, according to a PC World report.

Teri Goldstein of Sausalito, California, suffered the incident in the early days of the Windows 10 release.

Microsoft has been hammered by complaints that it has gotten increasingly aggressive about Windows 10 downloads to the point that it was basically forcing users to upgrade, with Microsoft downloading Windows 10 installation files in September for anyone with automatic updates enabled, according to the report.

That’s no small upgrade. That means many people unwittingly had a huge 6 gigabyte download — something that has harmed many users on fixed Internet data plans. It’s gotten so bad that PC World has labeled Microsoft’s tactics “malware-like.”

Microsoft has defended their upgrades as something that has to be agreed to by the user.

“Windows 10 was designed to be a service, which means it automatically gets better through periodic software updates,” Microsoft said in a statement. “The great news is that you usually don’t have to do anything to get the latest Windows 10 updates—they’ll download and install whenever they’re available. Most Windows updates focus on performance and security improvements to keep you humming 24/7. You’ll also see cool new features that we think you’ll like or other improvements that you’ve asked for. If you haven’t already, we invite you to join the Windows Insider Program so you can add your voice to the discussion, too.”
