Step 1: Backup Your Data

Installing or upgrading Windows can erase files. Always backup important data:

Use an external hard drive or USB drive.
Upload essential files to OneDrive or other cloud services.
Note down software licenses for applications like Microsoft Office.

Step 2: Create a Windows 11 Installation Media

You can install Windows 11 using a USB drive:

Download the Windows 11 Media Creation Tool from Microsoft’s official website.
Insert a USB drive with at least 8 GB of storage.
Run the Media Creation Tool → select Create installation media → choose your language, edition, and architecture (64-bit).
Select your USB drive as the destination.
Wait for the tool to download Windows 11 and create the bootable USB.

Step 3: Boot from the USB Drive

Insert the USB drive into the PC where you want to install Windows 11.
Restart the PC and enter the boot menu (usually F12, F2, Esc, or Del, depending on your PC).
Select the USB drive as the boot device.
Press Enter to boot from the USB drive.

Step 4: Start Windows 11 Installation

On the Windows Setup screen, choose your language, time, and keyboard layout, then click Next.
Click Install Now.
Enter your Windows 11 product key, or click I don’t have a product key (Windows will activate automatically if your device is digitally licensed).

Step 5: Choose Installation Type

You have two options:

Upgrade: Keep your files, apps, and settings (if upgrading from Windows 10).

💡 Tip: A Custom installation ensures a fresh system and better performance.

Step 6: Select Partition and Install

Choose the partition where Windows 11 will be installed.
You can delete existing partitions for a completely clean install (this erases all data on those partitions).

After installation:

Choose your region and keyboard layout.
Connect to Wi-Fi (required for updates and Microsoft account login).
Sign in with your Microsoft account (or create a new one).
Set up Windows Hello (face, fingerprint, or PIN).
Configure privacy settings and preferences.
Choose whether to enable OneDrive backup for your documents and pictures.

Step 8: Install Updates and Drivers

Go to Settings → Windows Update → Check for updates.
Install all available updates to ensure system stability and security.
Update device drivers via Device Manager or your manufacturer’s website.

Step 9: Install Your Apps and Restore Files

Reinstall essential software like Office, browsers, and security tools.
Restore your backup files from an external drive or cloud storage.
Customize system settings, display, and power options according to your preferences.

Tips for a Smooth Windows 11 Installation
