To install Windows 10 cleanly, you need to prepare tools, back up data, and perform the installation process correctly. 1. Make a bootable USB drive, use the media creation tool of Microsoft's official website, select the corresponding version and architecture, and ensure that the USB drive is at least 8GB and is constantly opened during the production process; 2. Set the BIOS to support booting from the USB drive, and it may need to manually adjust the startup sequence; 3. Back up important data before installation, because the clean installation will format the system disk, and it is recommended to transfer files to an external hard disk or cloud disk; 4. Select "Customize: Install Windows only (Advanced)" during installation, and create a new primary partition after deleting all partitions. Note that this operation will clear the hard disk data; 5. Select the system version during installation and enter the product key. If Windows 10 has been activated before, the license will usually be automatically identified; 6. After installation, the drivers and necessary software are installed first, and automatic updates are enabled to keep the system up-to-date. The entire process needs to be operated with caution, especially the backup and partitioning process, to ensure smooth installation and ensure data security.

To install Windows 10 cleanly, the core is to prepare the tools, back up the data, and execute the installation process correctly. The whole process is not complicated, but there are several key points that must be paid attention to.

Get ready for installation media

The first step is to create a bootable USB installation disk. You need to download the "Media Creation Tool" from Microsoft's official website and prepare a USB drive with at least 8GB capacity. After running this tool, select Create Installation Media for Another Computer, and follow the prompts to select the language, version, and architecture (usually 64-bit). After completion, the USB drive becomes a tool that can be used to install the system.

• Make sure your computer supports booting from USB drive
• Startup sequence may be set manually in the BIOS
• Do not interrupt the operation during production, otherwise it may fail

Back up important data

Be sure to back up your personal files before starting the installation. Because "clean installation" means that you have to format the system disk and all the original content will be cleared. You can copy the information to an external hard drive or cloud drive, or use backup software for mirror backup.

A common misunderstanding is that you will not lose data if you only uninstall the program or reinstall the system, but it is not the case. Especially if you plan to format the C drive, the documents, download directories, etc. inside will disappear. It is recommended to sort out what documents must be kept in advance to ensure that they have been transferred safely.

Perform the installation steps correctly

After inserting the USB drive, restart the computer, and select Boot from USB drive in the BIOS or boot menu. After entering the installation interface, select Custom: Install Windows only (Advanced). At this time you will see the disk partition interface.

If it was previously a dual system or multi-partition, you can select the drive letter to format. Newbie recommends deleting all partitions first and then creating a new primary partition, which is cleaner. However, be careful that doing so will clear the entire hard disk data, so the previous data backup is particularly important.

During the installation process, you will also be asked to select a version (such as Home Edition, Professional Edition) and enter the product key. If you have activated Windows 10 on this computer before, the system will automatically recognize the digital license and do not require reactivate.

Basic settings after installation

After the system is installed, the first thing is to install the driver. If some hardware such as network cards and graphics cards are not driverless, it may affect network connection or display effect. You can update online through the driver management software provided by motherboard manufacturers, or using the Device Manager.

Next is to install common software, such as browsers, office suites, antivirus software, etc. It is recommended not to install too much software at once to keep the system light. Also remember to turn on automatic updates to ensure that the system remains up to date.

Basically that's it. As long as you do your preparation, the installation process is actually smooth, but don’t forget that every step may affect the final experience, especially the partitioning and backup links are prone to errors.
