It’s almost six months after Microsoft first launched Windows 10 and the software giant just announced there are already 200 million devices with Windows 10. That is a huge number and such a fast pace of adoption in Microsoft’s history of operating system. To get to this number, the free upgrade from Windows 7 and 8.1 strategy is a big help. Microsoft knows that and it has pushed the upgrade very aggressive in recent months.

If you’re still on Windows 7 or 8.1, you pretty much have seen the upgrade utility pops up frequently to remind you to upgrade to Windows 10. It’s got more annoying now since Microsoft decided to push this utility as a required update, which allows it to be installed automatically via Windows Update. The utility called “Get Windows 10” (GWX) frequently annoys you with message to upgrade to Windows 10. If you hit the wrong button in its dialog, you can wake up next morning with your device now on Windows 10.

While Windows 10 definitely has many good stuff, it’s still not that stable or polished on some kinds of device as Windows 7 or 8.1. If you like to stick with your current Windows, here are somethings you can do to block the Windows 10 upgrade and stop that GWX utility.

How to block Windows 10 upgrade
