Sorry if this is the wrong forum to post this question. I have a really old computer Dell Optiplex 755 or something, 2007 model that I am running Windows Vista. I understand that this is extremely old, but I have not had any issues with it at all. It still works perfectly fine and actually seems to load up faster than my work computer which is pretty much up to date with all the latest software/security releases of Microsoft. I am just interested in bringing it up to date with some of the current software. I did just purchase 2 new computers a few days ago, but I don't see any reason in getting rid of this one, so I'd like to refresh it and keep it as a back up, maybe even store excess files on it. I believe the RAM is 4 gb, and it has about 75 gb of hard drive storage total. I understand it's not a lot by today's standards, but I can add a hard drive for storage, but I don't want to bog it down with excess files if it won't be able to keep up. I was wondering if adding more RAM and then upgrading the OS is all that's needed to upgrade it, or is there more? I only use it to send emails and browse online. Thanks.
