What I would do is first try backing up the driver store.

navigate to C:\Windows\System32\DriverStore then make a backup copy of the FileRepository folder.

After doing that, proceed to perform a clean install:

Go to a working computer, download, create a bootable copy, then perform a clean install.

Review the following guide for instructions and details about configuring your BIOS or UEFI boot settings for DVD, CD, USB or SD Card.

Once your computer is set to boot from the DVD, you should see this option. If you are installing from a retail Windows 10 USB thumb drive, you will be asked to select either 32 or 64 bit Windows 10. Learn more here https://www.groovypost.com/howto/choose-windows...

The Windows logo will appear on screen, this might be here for a while, as long as you see the animating dots, everything should be ok.

Select your Language, Time and Keyboard method then click Next.

Click Install now

Windows 10 setup will prompt you for a product key during installation a couple times. If you originally upgraded from Windows 7 or Windows 8/8.1 click the option 'I don't have a key' and 'Do this later' . If you have a Windows 10 product key, you can proceed to enter it.

Setup will also prompt you to select the edition you have a license for - Home or Pro. Please make sure you choose the right edition. If you choose the wrong edition, your only option will be to perform a clean install again.

The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:

Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core should install Windows 10 Home 



Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro should install Windows 10 Pro

Wait while setup prepares to copy files

Accept the license terms then click Next

Click Custom: Install Windows only (advanced)

NOTE: Sometimes Windows 10 setup can become confused if it see's a thumb drive. You might get a driver missing error or something to that effect. If you do, restart setup, but this time, when you arrive at the following screen, disconnect your thumb drive then go through Custom options. When setup is ready copy files, it will prompt you to reconnect the installation source (your USB).

Select the drive then click New

NOTE: If you have multiple partitions listed, select each one (starting at the bottom), then click delete until there is only a single (one) unallocated drive displayed in the window.

Select the unallocated drive listed, click New, click Apply then OK

This will split the drive into multiple partitions, select the Primary partition then click Next.

NOTE: The System Reserved partition is where recovery files are kept for diagnostics and repairing damaged Windows 10 files; or even reinstall Windows 10.

Wait while Windows installs

When this phase of setup is complete, Windows will automatically restart then reboot into setup again.

Windows is detecting and installing your hardware. After this is complete, Windows will restart one last time.

Hi Andie. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

When you first Upgraded it assigned a permanent Digital License for the PC in Microsoft Activation servers so that you can reinstall Windows 10 at any time, skipping the Product Key during install, and it will reactivate afterwards when you connect to the internet and it phones home to find your hardware profile confirming the Digital License.

You can do the in-place Upgrade over the existing Windows by installing the Media Creation Tool from this link http://windows.microsoft.com/en-us/windows-10/m... choose Download Tool Now, install the tool, open it and choose Upgrade this PC Now. This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.

Or if you want a better install, since you already have a permanent Digital License, do the gold standard Clean Install in this link which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

To create bootable Windows 10 Installation Media (on another PC if necessary) install Media Creation Tool and follow the directions in the middle of the download page here: https://www.microsoft.com/en-hk/software-downlo...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key for your PC maker given in this chart: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, then on second screen choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, select the Unallocated Space, click Next to let it create and format the needed partitions and start install - this makes it foolproof.

You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC because you will learn everything that works best and how to apply it with your own hands.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
