How will older Windows versions be supported?

I need to share a situation where I was forced to work on an old office PC while still using Windows XP and looking for ways to protect against security vulnerabilities. At the time, the client said the hardware was too limited and it wasn’t possible to get a new system. In the end, I decided to isolate Windows XP on a local network: I set up a system that only ran the necessary applications, disconnected it from the internet, and redirected it to a local DNS server. Also, as odd as it sounds now, I downloaded updates manually and installed them via USB. A few months later, a virus attack happened, but since the system was offline, the infection was limited to local file sharing. Later, I made sure Windows XP could share data using tools like Resilio Sync while maintaining an isolated network. Many in the community use similar approaches, especially when working with industrial devices or old software. The key takeaway: if upgrading isn’t an option, isolating the hardware and controlling it manually might be the best solution.

Just like custom ROMs can keep old Android devices updated for a long time, it's possible to extend the lifespan of Windows using certain methods. For example, even on systems that are no longer officially supported like Windows XP, community-developed patches (such as security updates released for POSReady 2009) can give them a bit more life. The difference is that on Android, this requires root access, while on Windows, it can be done with just registry tweaks or third-party patches. On the other hand, the biggest factor that "killed" Windows 7 users was the end of support—similar to how certain iPhone models continue to be used even after Apple stops providing support. But it's worth noting that Windows 10 and 11 now offer much longer support periods. For running old Windows-dependent applications, I've found virtual machines (VMs) or compatibility layers like Wine/Proton to be effective—kind of like trying to run retro games on modern consoles, but through more official means.

I recently had to help a relative who was still using Windows XP. Their old PC originally came with a Windows 7 license, but they had downgraded to XP. First, I reinstalled Windows 7, applied all the updates, and installed only the necessary programs. The issue with an old factory software not being compatible with newer systems was solved by setting up a virtual machine with XP, keeping it both secure and functional.

What should I watch out for with older systems like Windows XP or Vista? For example, how can I close security vulnerabilities on devices connected to the network?

This topic always reminds me of the struggles of those who had to unroot their Android devices. Trying to run new software on an outdated Windows system (like XP or 7) is a lot like flashing a Custom ROM on a 2010 smartphone: theoretically possible, but practically full of limitations. For example, official support for Windows XP ended back in 2014, yet there are still people willing to live with its security vulnerabilities. The biggest issue here is that most modern browsers and applications simply won’t work anymore. The last Firefox versions compatible with XP are nearly extinct, and Chrome or Edge no longer provide support. At this point, you’re either forced into isolation (running it in a VM or sandbox) or have to take the radical step of switching to a Linux distribution. My advice? If you *must* keep the old system running (say, for a hobby project like building a retro gaming console or tracking down drivers for an industrial device), the safest route is to run it in a Windows 7 or 10 VM (virtual machine). Tools like VirtualBox or VMware let you use it in an isolated environment, protected from the main system. It’s a bit like trying to hide root access on Android using Magisk—you preserve the old system while adding a layer of protection against modern threats. But remember, this is only a temporary fix. Old Windows versions won’t stay supported forever, so eventually, you’ll need to plan an upgrade—or switch to a completely different OS.
