I am a great believer in refurbishing old systems to keep them running. I recently refurbished and upgraded two 12-year-old laptops, now running Windows 10 quite well. However, there comes a point when it's not worth it. Your laptop is effectively beyond that point. Your laptop is 18 years old. It has only a Pentium III processor and PC133 SDRAM. To put that in perspective, since then we have had DDR1 RAM, then DDR2, then DDR3, then DDR4 and now DDR5. I find it not generally worthwhile to refurbish any system older than one that can accept DDR3 RAM, and yours is three generations older than that. You cannot run any modern Windows OS on it. Period. If you are able to install Windows XP, you would have an incredibly insecure computer that will receive no updates and is likely to become infected with malware. Personally, I would send it to recycling. If you want to experiment, I would suggest that you install a Linux OS made for weaker systems, such as Lubuntu or Puppy. Or, install Chrome Flex. While it would still be very slow, at least it would not be so insecure as Windows XP.
I've been given an old latitude C610 laptop and I can't figure out how to reset it to factory settings. I've tried looking in the BIOS  but no luck. I'm probably being dumb but i can't figure it out  Very appreciative of any help!
Latitude C610 reset to factory settings?
