How to downgrade or uninstall Windows 10:
Part 1: Launch windows settings (windows key, bottom right should be a settings section)
Step 2: Look for an option called “Go back to Windows x.x” – where ‘x.x’ is the version of Windows you were running earlier. Click the Get started button to begin the roll back process. This method should work just fine no matter which version of Windows you are coming from
Step 3: Microsoft will now ask you to provide some feedback as to why you’re choosing to downgrade. Once that’s done, click Next.
Step 4: Now simply follow the on-screen prompts and instructions, doing as you’re told as Windows 10 is uninstalled from your system. If your old Windows was password protected, you will be asked for it to authorize the downgrade.
I suggest that you give windows 10 some time, its always best to be on the latest OS that you can be on!
