How to do a clean install of Windows 10

Here's three ways to install a clean version of Microsoft's operating system onto any PC.

For a system already running Windows 10

If your computer already runs Windows 10, the easiest way to refresh the machine is to reset it.

First, on the Start menu, click Settings.

 

 

Step 1: From the Windows 10 Start Menu, click on Settings.
 

On the Settings page, click on the Update & Security button.

Step 2: On the Settings page, click on the button that reads Update & security.

Choose to Reset this PC.

Step 3: Now on the update and security page, click on Recovery, then under Reset This PC,click on Get Started.
 

Choose to remove everything.

Step 4: Choose the provided option to Remove everything. Alternatively, you can choose to retain your personal files (such as those in the Desktop and Documents folders) which will keep the files in your profile intact.

Only choose to clean the drive if you intend to give away or sell the computer after the reset.

Note that the last option, Restore factory settings, is only available in certain machines and will reinstall the original Windows system that was on your computer when you bought it. You don't want to choose this option, unless your computer originally came with Windows 10.


Step 5: You will be presented with the option to Just remove my files or to Remove files and clean the drive. Basically, if you intend to keep the computer for yourself, pick the first option. If you intend to give it away or sell it after the reset, choose the second option, which will take much longer to complete.
After choosing an option, click on the Reset button and that's it. The computer will restart and after somewhere between 10 minutes to half an hour, or maybe longer depending on the speed of the machine, you will have yourself a computer with Windows 10 freshly installed. Note that resetting your machine in this way means you'll lose the option to roll back to the previous Windows

For Windows 7/8 machines

If your computer still runs Windows 7 or 8, you want to avoid upgrading using Windows Update. Instead make yourself a Windows 10 installation disc. I prefer using a USB flash drive (thumb drive) since it works with all computers, including those without an optical drive. You'll need a drive that's 3GB or larger. Here are the steps.

Step 1: Go to Microsoft's Windows 10 download page and click on Download tool now to get the latest media creation tool.

Pick the option to create installation media.

Step 2: Run the downloaded tool, choose Create installation media for another PC then click Next.
 

Choose the language, edition and architecture for Windows 10.

Step 3: In this step, you select the Language, Edition and Architecture for Windows 10, then click Next.

Pick USB flash drive as the media to use.

Note that the N version of Windows 10 is for some European countries and will not include Windows Media Player. Read more about these specifications here. If you choose to make the installation media for both 32-and 64-bit Windows, you will need a thumb drive that has at least 6GB of storage space. If you intend to install Windows 10 on the current computer, you can check the Use the recommended options for this computer box.

Step 4: Choose USB flash drive.

Pick the Thumb drive to use as the installation media.

Step 5: Insert the flash drive into the computer's USB port and click Next. After the drive is selected the tool will start downloading Windows 10. Depending on the speed of your internet connection, the download can take anywhere from a few minutes to a couple of hours. Once the download is done, the tool will takes another few minutes to turn the flash drive into Windows 10 installation media. You then can use this flash drive to upgrade or install Windows on any computer.

Double clicking on the Setup file will begin the upgrading process.

Step 6: Insert the installation media flash drive into a computer running Windows 7 or 8 that you want to upgrade. Open the drive in Explorer and double click on the Setup file. The upgrading process will start.

You can change what to keep during a manual Windows 10 upgrade.

Step 7: After a short preparation, including checking for updates from the internet and asking you to agree to terms and conditions, you will be greeted with the Ready to Install dialog. Click on Change what to keep.

Step 8: In the next step, you can choose to keep Nothing (so that you'll have a truly fresh Windows 10 install), Keep personal files only (your documents, music, photos and so on will remain intact) or Keep personal files, apps or Windows settings (you will not have a clean installation of Windows 10). After that click Next.
Follow the rest of the installation and once it's done, if you have pick the option to keep nothing or just personal files, you will have yourself a clean installation of Windows 10 on your machine.
