Can you upgrade to Windows 10 again after downgrading to Windows 8.1?
I am having too much trouble with Windows 10. (Laptop won't wake up from sleep or shut down correctly, and startup time increased significantly.) Therefore, I'm considering downgrading back to Windows 8.1 and waiting a few moths for all these issues to
be solved. So, could I upgrade again to Windows 10 after downgrading from it?
Once you have the installation media, follow the steps:
Start your computer from the installation media. Insert the disk or USB stick and restart your computer. If you see a message asking you to “Press any key to boot from DVD,” do so. If you don’t see the message, you might need to
change the boot order in your computer's BIOS settings so that it first starts from the disk or USB. When you see the 'Install Windows' page, tap or click 'Repair your computer' link to start the Windows Recovery Environment.
In the Windows Recovery Environment, on the Choose an option screen, click 'Troubleshoot'.
Click, Advanced Options and then click on 'Automatic Repair'.
After this complete the repair and see if you are able to boot in to your computer.
If repairing does not work you may follow below steps and downgrade Windows 10
