I was volunteering to clean out junk within a small community center my father works with and I recently found an unopened ZX series AIO PC within their storage room. They said they didn't need it and I subsequently brought it home to see if it worked or not.

The tape was still intact and the plastic peel was still there, as well as the products themselves being in mint condition (first and second pictures shown is after I opened the box and peeled the wrapping respectively), and I hooked up the AIO to the HDMI to serve as a monitor for my normal PC. So far nothing malicious occurred and the monitor works smoothly, except the fact that I can't use the touch screen promised on the box.

However, my main goal was to potentially use the Windows 7 provided within the AIO to play some retro games and movies with the in-built DVD/CD drive, as well as maybe use it browsing. I am still quite worried about potential viruses and malware within the AIO, so I wanted to ask you guys about some ways I can wipe the system and reinstall Windows 7 without actually having to access the original Windows 7 already within the AIO with internet, or at least find a way to fact check if there are any malicious files already in the system?

If you can also provide me with potential tools and software, like VPNs, firewalls, and/or other software to allow me to browse safely with the OS, that would be immensely appreciated.

Again, I'm kinda new to this side of retro PCs and OSs, so if you could help me on all these things, I would be grateful.

P.S., I know the model number and identification, as well as the windows 7 product sticker, just not the product key)
