@Goofprog: Thanks for the tip.
I ran the Update Command all went well I had only been doing any updates via the Icon in the bottom right corner of the screen.
I had already enabled UFW. I was wondering about any AntiVirus? Am I right to be under the impression I don't need it?
Linux Mint XFCE is ruunning really well on the PC, really snappy. I had added 2Gb extrta RAM making a grand total of 4 so that probably helped too. I honestly can't fault it
Regarding the Microcode, I can't remeber if I installed it or not in the end...I must check when I next use the machine...Is there a command line that would telll me that information?
Anyhow thanks again
I feel for the most part doing the Updates from the Updater is fine, that's how I always do it...why...because I'm lazy, and it always seems to work fine. If I'm having issues I may run the Update Command as I showed you.
Yes, you are fine without any Antivirus as long as you practice good browsing. I've had some troubles with Linux getting buggered up, what is actually happening I don't know. Usually Cleaning Browser Data will fix such things. The Browser is the weak link, so you should get some good add-ons to protect you. I use NoScript in Firefox if I'm browsing questionable or unfamiliar sites. UFW is very good, and it don't really need tweaking, it's defaults are great, until you learn how to tweak it there is probably no need unless you just want to learn.
Xfce, I like it and don't like it haha. It is good, but you have to like the Desktop Environment, and I don't. I do like the easily expandable Menu! If I were you, and came to a point that I needed to re-install, would try out Mint Mate, it is a much fuller desktop. What does "fuller" mean, I don't know LOL. Comes with lot's more programs installed by default etc. Seems easier to me to set up and use, and feels like a real full fledged desktop.
microcode: Don't worry, if it works your all good, whether it is the old or new one, until you have a issue I would not worry. I've installed it on some machines and on others not, hasn't mattered on my machines. I do know how to produce a list of installed packages, but need to be on Linux Box to run them to be sure I'm steering you right. Some of the Staff here taught me this so maybe they will chime in before me.
You can use this one safely if it was installed recently. NickAu showed me this one:
cat /var/log/dpkg.log | grep "\ install\ "
Keep it up your doing great! Wish I could save more old XP and Vista machines this way, but it's a lot of work and most people don't appreciate that. I do it if I have time and come across good machines/donors, then will try to sell them real cheap, most charities around here don't want them.
