Method 2. Clean/Fresh Install Windows

Microsoft has a Media Creation tool to perform clean/fresh Windows installation. You need to create Windows 10 installation media with a USB flash drive, CD, or DVD to perform a fresh install on Windows. 

Preparations:

• A strong Internet connection.
• A USB flash drive or DVD (at least 16GB of free space).

Part 1. Creating Windows Installation Media for Reinstalling Windows

Step 1. Get the official Windows 10 Media Creation Tool from Microsoft.

Step 2. Open the Media Creation Tool to see the Windows setup screen. 

Select Create Installation Media and click Next. To avoid issues in the future, ensure the USB is connected and recognizable.

Step 3: Select the language, architecture, and Windows edition to create the installation media. To access Windows recommended options, tick the "Use the recommended options for this PC" box.

Step 4: In the Choose which media to use window, Choose the USB flash drive and click Next.

Step 5: Find the USB under the Removable drives list and click Next.

Step 6. As soon as MCT creates installation media, it shows "Your USB flash drive is ready" on the screen. You can now use this drive to boot up your computer and reinstall Windows 10.

Part 2: Perform a Clean Install from the USB flash drive

Step 1. Connect the installation media to the PC and change the boot order to boot from it.

Step 2. After you boot the PC, the initial Windows Setup options are: Select Language, Time, Currency, and Keyboard Format, and click Next.

Step 3. Click on Install Now. 

Step 4. Click on I don't have a product key. If your Windows OS is activated, it automatically reactivates it after the installation. Accept the terms and conditions and click Next to continue with Windows reinstallation.

Step 1. Open Settings > Update & Security > Recovery. Click the Reset this PC and click on Get Started to start.

Step 2. As discussed in the reinstall options above, you can keep your files before reinstalling Widows.

The Remove Everything option will install Windows 10 with the latest default settings. On the other hand, the Keep My Files option removes all the apps you have installed but keeps the personal files. Select one based on your needs. 

Step 3. The following window asks, "How would you like to reinstall Windows?"

This again provides two options: Cloud download and local reinstall. Cloud download fetches the latest files from Microsoft on the net, whereas the Local reinstall utilizes the current system files to rebuild a fresh copy of Windows OS.

Step 5. A final window lists all the processes that will happen during the reset. You can review the details and list of apps to be removed and click Reset.

Step 6. Wait for the Reset process to complete, and your PC will now have Windows 10. 

Method 4. Use Windows ISO Image File

Another easy option to reinstall Windows 10 without losing data is to use an ISO image file. Image files are primarily used to recover/repair the Windows OS and help reinstall Windows. We will now see how to download and run the ISO file to perform Windows 10 reinstallation.

Step 1. Create an installation ISO file using the Windows Media Creation tool. 

Step 2. You should double-click to mount the ISO file. If you have Windows 7, you will need other tools to mount the ISO file.

Step 3. In the root directory, double-click on Setup.exe to start the process.

Step 4. The Windows 10 Setup will be up and prompt you to select important updates. Select download and install updates or not right now to proceed.

Step 6. Here, you can choose what files you want to keep. These options let you keep apps, personal files, and Windows settings. You will have flexible options for personal files and data. Select the first option to keep data and software apps and click Next.
