Bugs, lack of reliability, a convoluted, redundant, and ugly UI, privacy issues, a lack of customization options and a lack of control over OS operation (including Windows Update), tons of bloatware, settings resetting after updates, a massive amount of spying and data-theft, in-OS ads, compatibility issues with some older programs, Microsoft's dishonesty, lack of respect for, and manipulation of Windows owners. Those are some of the issues that I have with Windows 10.
