I'm still running XP as well. Was at 3.6 GHz for the last 6 years. I wanted to upgrade due to fears of imminent hardware failure, and I finally found a faster/better MB with XP drivers. I'm now running slightly OC at 4.6 GHz (air cooling) and I can use the newer PCI-Express graphics cards & USB 3.1. I'm ecstatic..
Also I still use XP Pro SP3 32-bit, but my available system memory is still at 3.25 GB with a 1 GB graphics card, a 4 GB Ramdrive, and another 2 GB Ramdrive. (You do the math..) It took a little tweaking but I can use the ram above the 4GB boundary. I was never able to use more than 2 GB of ram with my old system, and it really does make a huge difference. One other cool note, I finally figured out how to switch to AHCI mode after windows was already installed in normal IDE mode, (I don't use a floppy drive any more, it's all thumbdrives now), so that's the icing on the cake. The last thing I need to do, is find a generic (non-branded) trim program for XP so I can keep all my future SSDs in top shape without having to switch to my newer games Win7 partition to trim them.
For anyone who asks why I bother with XP, my top 3 reasons:
1) I know how to bend it to my will after many years and failed tweaking attempts.
(I mastered the art of tweaking it any way I want.)
(I have multiple desktops with different shortcuts on them depending on my mood, switchable via F-keys, and custom batch files to switch into any mode I want IE: turning off everything for gaming mode, just to list one..)
2) It no longer spies on me like all the newer OSs do.
(I didn't feel like being unsecure for years while everyone tried to figure the new OSs out.)
(I learned every settings & hack required to keep it from phoning home to M$. And you have to do some serious hacking IE: hex editing system files to accomplish that. Not to mention certain HOSTS entrees, and using the right security software.)
3. I have a huge library of programs on my drive to do anything I want.
(IE: Games, music (24&36-bit FLAC), movies, custom browser setups (new & old but reliable), office, editing, etc...)
(Basically my system is very easy to use, and I've already trained myself for long enough... Now I'm going to enjoy it.)
I've already bought multiple motherboards, extra power supplies (with the same connectors), a few sets
of ram, and a few more CPUs, that are going to sit in storage until my current board/hardware dies. Then
all I have to do is switch out failed components. I'm done with the rat race.
PS - To the last comment.. I still have a one-time pad encryption program I wrote in batch code on
Win98SE that I can't even run in XP due to the $@#*s changing msdos around. I guess it was a good idea I
made a bootable thumbdrive version of 98SE (under 250 MB) that I can still boot up in any computer to
use it & keep working on future versions. So to those who say move on, screw you. (Ask the banks why
they still have dos on their computers).
