I'm planning to keep old Windows installations running longer, but I lack clear strategies. What general approaches do you recommend for maintaining security, compatibility, and performance? For example, I'm interested in methods for regular data backups, network isolation, using virtual machines, or alternative browsers. Tips on updating drivers without official updates would also be helpful. How do you handle older software that is no longer supported, and what tools do you use to keep the system stable? I look forward to your experiences and recommendations.
How do you best deal with outdated Windows versions in everyday life?

A proven approach is to first encapsulate the old Windows system in a virtualized environment. This allows the host OS (e.g., Windows 10/11) to serve as security and network isolation while the legacy system runs in a VM with network access restricted (e.g., only internal LAN routes). For regular backups, I recommend an incremental imaging tool like Macrium Reflect or the built-in WBAdmin, which automatically saves a snapshot file to a separate NAS daily.
In comparison, a physical dual-boot setup can offer better performance, but the risk of unrestricted network attacks increases because the old OS has direct network access. If you still want to stick with physical hardware, use a dedicated VLAN with restrictive firewall rules and only use a secured browser (e.g., Firefox ESR with WebGL/Flash disabled). Driver updates can often be handled via tools like Snappy Driver Installer or by downloading generic INF files from the manufacturer’s website—just remember to disable signature checks before installing and stabilize the system afterward using Driver Verifier. This way, the combination of VM isolation, automated snapshots, and cautious driver updates strikes a good balance between security and usability.
I rely on regular image backups with Macrium Reflect and isolate the old system behind a separate network switch, so it's only accessible via a guest Wi-Fi network. I also install a lightweight portable browser (e.g., Firefox Portable), use Windows compatibility mode along with Driver Booster for orphaned drivers, and run critical old programs in a VM to ensure stability and security.
