If you want to downgrade your computer to Windows 7 or Window 8/8.1 then follow the tips outlined below:

Downgrade Windows 10 for computers to Windows 7 or Windows 8/8.1

Go Back to Windows 7 or 8.1

The good news here is that if you upgraded your computer to Windows 10, i.e, you didn't perform a clean install then you're in luck! You can revert to the previous version of Windows by using the recovery tool preinstalled on the PC when you updated to Windows 10. To use it:

  1. Open the Start menu and select Settings.
  2. Click the “Update & security” icon
  3. Select “Recovery.”

From here you can see an option that reads "Go back to Windows 7" or "Go back to Windows 8.1". You need to click the button that reads "Get Started" and process of uninstalling Windows 10 will begin. Of course, before you restore your previous version of Windows, Microsoft will prompt you to fill out a short survey that asks why you have chosen to downgrade your device. Follow the prompts and you'll have your old version of Windows in no time.

Uninstalling Windows 10

The above option is only available if you've just upgraded, if a month has passed (Windows 10 is also set to automatically remove the old Windows installation files after a month) since your update or if you already performed a disk cleanup and removed "Previous Windows Installations"  or if you have manually deleted the C:Windows.old folder, you will not be able to use the easy method above.

Video: how to uninstall Windows 10 and downgrade to Windows 7 or 8.1

Not a fan of reading? Not everyone is, so, here's a short video showing you how to delete Windows 10 and install your previous version of Windows on your computer. If you  don't want to watch the video tutorial then you can always continue reading the article.

How to Downgrade if Windows 10 Doesn't Give You The Option

If you deleted the data or you're past the month limit then you will need to perform a clean install of the operating system you're trying to downgrade to. Be Sure that you have your product key (not the Windows 10 product key but the one for your previous Windows installation).

Download the OS you want to install. You can find the official ISO files on the Microsoft website. You will need to burn the files to a DVD or mount the ISO files using a virtual replication software. You can also create a USB drive using the Windows USB/DVD Tool. Using any of the options will allow you to boot and reinstall Windows 7 or Windows 8.1. Before you do this you should make a copy(backup) of all the important files on your computer.

In order for the reversion to be complete you will need your PRODUCT KEY. If you can't find or don't have a product key you will need to purchase a new one from Microsoft.

Reinstall a clean copy of Windows 7 / 8.1

As always, in Windows devices also you have the option of removing the current system from your hard drive by re-installing another version of Windows. However, it is important to follow these preliminary steps:

Make a backup of your files

With the easy way, making a backup was something recommended but not essential, but to make a clean reinstall the backup becomes mandatory if you do not want to lose our personal files.

On this end, Windows 10 includes 2 sets of backups: a more modern one, called File History, but that is only compatible with Windows 8.1, there is also an older version with less features, but offers compatibility with Windows 7.

  • To make a backup using File History should go to Settings> Update and Security> Backup and then select "Add Drive". Then you need to connect an external drive with sufficient space, and wait for the first backup is complete.
  • To make a copy that is Windows 7 compatible also go to Settings> Update and Security> Backup, but then select the option Go to Backup and Restore (Windows 7).

    A Control Panel window, in which you must click Configure backup appears. Finally, just connect an external drive with enough space, and follow the wizard until the backup is complete.

Create a DVD or USB drive to install Windows 7 / 8.1

To place a clean installation you need a physical medium to store the installation files for Windows 7 / 8.1, so you can start your PC directly from this unit (without entering Windows 10) and start the process that will overwrite the file system.

The ideal way would be an installation disk provided by the manufacturer, but if you do not have it, Microsoft allows you to download the installation files directly from the web, completely legal.

Simply go to this page , choose the version you want to download (7 or 8.1), follow the instructions. There are 2 different courses of action depending on if you want to downgrade to Windows 7 or to Windows 8.1.

In the case of Windows 7 you will be required first to enter a valid product key, you can use the same one that came with your PC, or purchase a retail license of Windows 7. Then you need to indicate if you want to download 64-or 32-bit (to see which version you need, you have to go to Settings> System> About> System type within Windows 10), and finally start downloading the ISO file.

Once downloaded, Windows 10 allows you to save the files  directly to a DVD without requiring additional software. Simply insert a blank disc, then right-click on the ISO file and select the Save option.

To convert the ISO file to a USB drive you need to download and install this tool , run it and follow the wizard's instructions.

In the case of Windows 8.1 the process is a bit easier. You do not need to enter an activation key in the website, and what you download is an ISO file, but a tool called Media Tool Creator, which allows you to directly create DVDs and USB drives installations of Windows 8.1.

Simply run the downloaded file, follow the steps in the wizard, and you're set to go. Of course, we must correctly indicate which edition of Windows 8.1 and architecture you want to install. This is very important because your activation key will only work with the particular edition of Windows 8.1: we had installed before upgrading to Windows 10.

The system architecture you can check in Windows 10, via Settings> System> About> System type. And in the same section "About" it should show which version of Windows 10 you have installed.

And start installation

Once you have already created a backup with the corresponding method, and got the physical installation media, all that is left is to begin the installation itself.

This requires inserting / connecting the DVD or USB drive the computer, restart it, and make sure that the system boots from the installation drive, not from Windows 10. This Windows 7 / 8.1 installation wizard appears.

Once there just follow the instructions displayed, but make sure that when asked for the type of installation you want, select the "Custom Install" option instead of "Update".

Then, all existing partitions on the PC will be displayed. You must choose the one that is installed with Windows 10, and delete its contents, and choose it as drive to install Windows 7 / 8.1.

The end result will be a clean installation of your previous operating system. You can restore your files using the backup you made in step 1. However, through this method there is no way to recover previously installed programs and applications: you must manually reinstall them all (though many modern applications can be bulk re-installed from the Windows 8.1 Store ).

Yet Another easy method: Restore factory settings

Finally, there is an equally easy method to uninstall Windows 10 from your system, which also delivers all the performance benefits of a clean install. This is the option to restore factory settings, which is also available from the Windows 10 app settings.

This option restores your PC to the state it was in when we bought it at the store and used it for the first time, including to its original operating system. It uses the files from the recovery partition created by the manufacturer.

To restore the PC with this option you have to go to Settings> Update and security> Recovery and press the "Start" button in the "Reset the PC".

After that a dialog box appears with three options:

  • Keep my files
  • Remove All
  • Restore factory settings

As you might have guessed, the option to be selected is the latter. After that, just follow the instructions displayed on the system.

All very simple, but still with some caveats. First, as you can imagine, this method completely erases your files and applications, so here you also need to back up. Second, there will be some cases where this option is not available, either because the manufacturer had not enabled, or because you deleted the recovery files. And third, this mechanism only serves to return to Windows 8 or Windows 8.1, not to Windows 7.

What experience have you had with these methods to uninstall Windows 10? Is there any other way you have given them better?
