One way to avoid the problem is that Microsoft offers "Signature Editions" of third-party notebooks which comes without any bloatware on them. However, you can only buy them them directly from Microsoft online and the number of Signature Edition models is limited.
But there is a help on the way.
This summer, Microsoft will be releasing a major "Anniversary" update to Windows 10. And one of the included features will be a "clean install" option.
The app will be available under the Settings heading. When running it, this will basically wipe the old Windows 10 installation and replace it with a clean install, giving you what they call a "fresh start."
