I regretted "upgrading" to Windows 10. The flat icons are ugly, and it's starting to hang dead on me after one month of use. Even ctrl-alt-del is useless when it goes unresponsive. The only option is to press the power button for 10 seconds to shut down manually. They can't get it right and we are back to Windows 3.1. What's worse is that they deleted the option for me to go back to Windows 7.
