Method 2. Reinstalling via Windows Media Creation Tool

If you want a fresh start or can’t fix your system any other way, reinstalling Windows 10 with Microsoft’s Media Creation Tool is a reliable option. Here’s how to download the tool, create a bootable USB, and perform a clean installation step by step.

Create a Bootable USB Drive

Step 1: Go to Microsoft’s official website and download the Windows Media Creation Tool. Run the downloaded MediaCreationTool.exe file.

Step 2: Accept the license terms, then choose Create installation media (USB flash drive, DVD, or ISO file) for another PC and click Next.

Step 3: Select your preferred language, Windows edition, and system architecture (64-bit or 32-bit), then click Next.

Step 4: Choose USB flash drive as the media type and insert a USB drive with at least 8 GB free (make sure to back up any important files, as this will erase the drive).

Step 5: Select your USB drive from the list and click Next. The tool will download Windows 10 and create the bootable USB for you.

Perform a Clean Installation Using the USB

Step 1: Insert the bootable USB into the PC you want to reinstall Windows on.

Step 2: Restart your PC and enter the boot menu by pressing keys like F12, F10, or Esc (this varies by manufacturer). Select your USB drive to boot from.

Step 3: When the Windows Setup screen appears, choose your language, time, and keyboard preferences, then click Next.

Step 4: Click Install now.

Step 5: Enter your product key if prompted, or click I don’t have a product key if your PC has a digital license that activates automatically later.

Step 6: Select Custom: Install Windows only (advanced) for a clean install.

Step 7: Choose the partition where Windows is currently installed (usually Drive 0), then click Format to erase the old system files. Confirm the format, select the partition again, and click Next to continue.

Step 8: Windows will now install. Your PC may restart multiple times during the process—just wait patiently.

Following these steps will give you a fresh, clean Windows 10 installation and help fix persistent system problems.

Method 3. Running Windows Setup from an ISO Partition via Command Prompt

If you prefer a hands-on way to reinstall Windows 10 without creating external media like a USB drive, you can mount the Windows 10 ISO file directly on your PC and launch the installation using Command Prompt. This method is great if you already have the ISO downloaded and want a straightforward reinstall.

Step 1: Mount the Windows 10 ISO File

Right-click the ISO and choose Mount—this will create a virtual drive that acts like a DVD containing the Windows installation files.

Download the official Windows 10 ISO from Microsoft’s website if you haven’t already.
Locate the ISO file in File Explorer.

Step 2: Start Windows Setup via Command Prompt

Press Win + X and select Command Prompt (Admin) or Windows Terminal (Admin) to open it with administrator rights.
In the command window, type the drive letter of the mounted ISO followed by a colon (for example, E:) and press Enter to switch to that virtual drive.
Type setup.exe and hit Enter to launch the Windows Setup program.
Follow the on-screen prompts to reinstall Windows 10. When asked, choose whether to keep your personal files and apps, keep personal files only, or start fresh with a clean install.
