Although with certain models it may be possible to run Windows on a Chromebook the user experience will leave a lot to be desired if your lucky to be successful.
Both Google and Microsoft do not support Windows 10 running on Chromebook-focused hardware.
That means you may not find Microsoft-certified drivers and must fall back on possible third-party solutions.
The biggest issue regarding Windows 10 on Chromebooks, however, is the process of installing Microsoft’s platform. Most Chromebooks include a write-protect screw on the motherboard that prevents you from installing any operating system. To get Windows 10 on the machine, you’ll need to remove the bottom shell, remove the screw from the motherboard, and then flash new firmware.
So being technically possible like I said with certain models most users will not go through so much trouble to get a lousy computer experience due to hardware limits. If you need Windows on your laptop it would be better to buy one you can afford from one of the major manufactures out there instead of trying to fit a round peg in a square hole.
If your set on trying to get another operating system on a Chromebook, you would better off with trying to install Linux instead of Windows. But do extensive research before you go down that road as you will find useful information from others who did it.
