This means they will no longer receive security updates to protect you from vulnerabilities. However, if you still need them to run older software, you can safely download them from archives and trusted third-party sources.

If you are looking for a super-fast, bloatware-free experience, Windows 11 IoT Enterprise LTSC is your best bet. It is an official, lightweight edition modified by Microsoft for enterprise devices. By default, it strips away heavy consumer apps (like the Microsoft Store, Xbox integration, and Cortana), giving you unmatched speed and efficiency on older computers.

Pro Tip: Getting Back Windows Apps in LTSC Edition

Since the Windows LTSC edition is stripped-down for performance, it comes without the Microsoft Store and modern built-in apps (such as the modern Media Player, Notepad, or Calculator). However, you don't need to install the full Store to get them back! You can simply browse the web-based Microsoft Store Online, grab your preferred apps, and install them directly on your PC.
