I've been through the ESU process for a small business setup, and it has pros and cons. On the plus side, it's great for continuity; you can keep using your existing hardware and software without a hitch while still receiving critical security updates. This can be particularly helpful if you have legacy applications that might not work with newer Windows versions without additional investment. The downside is that it's a temporary fix. Every year, you'll need to reassess and decide whether to renew or finally upgrade. Costs can add up, and it's important to anticipate when support will eventually end entirely. In my experience, I found investing time and resources into planning an upgrade to Windows 10 or 11 was more sustainable in the long run. Newer versions offer better security by design and enhance productivity with updated features. If you're running vital business operations, consider the hidden costs of staying outdated, like potential downtime or compatibility issues, against the short-term ease of staying on Windows 7.
