Open your browser, search for "Windows 10 download," and click on the official Microsoft.com result. Then, click "Download tool now" to get the installation utility.
Once the tool is downloaded, run the installer. Click "Yes" to proceed, and then accept the terms and conditions.
Select the option "Upgrade this PC now" to upgrade your current Windows version to Windows 10 and click "Next." The installer will then begin downloading the Windows 10 files, which are about 5 gigabytes.
The installer may restart several times, which is normal. Ensure "Keep personal files and apps" is selected to retain your data. It's recommended to back up your personal files to an external drive or cloud storage before proceeding for extra safety.
Click "Install" to begin the official installation process. This can take several hours, and your computer will restart automatically as needed. Do not turn off or unplug your computer during this stage.
Once the installation is complete, your computer will boot up to the new Windows 10 desktop, ready for use.
