🕒 Prepare Before Starting the Update
Before performing any Windows update, it’s important to ensure your system is ready to avoid interruptions or failures. First, make sure you have enough free disk space available—especially if you’re installing a feature update. A minimum of 20 GB is often recommended.
Use a stable internet connection to prevent corrupt downloads or failed update attempts. Avoid updating over public or unstable Wi-Fi networks. Also, do not turn off your computer during the Windows update process. If your system prompts you to restart your computer, do it promptly to allow updates to install properly.
Ideally, schedule your updates when you have sufficient free time, as the entire process may take anywhere from 15 minutes to over an hour, depending on your device’s performance and internet speed.
