Well I finally had to bite the bullet and upgrade the desktop computer (yes, I still use one) as the windows XP install had a corrupted file after a power outage, would not boot and I could not repair the install.
So, I bought 2 solid state drives, one for programs and one for data (the idea is the operating system can be refreshed without affecting data). Windows 8 upgrade software bought and installed (thanks to Lionel as he had all the extra bits I did not have).
After a bit of a learning curve, all works great. Boot up and program speed is like the computer is supercharged, it is that much better. The solid state drives must account for a fair bit of this, but windows 8 is supposed to be faster as well. It has not taken long to get used to the way it operates, as there is a desktop option in there. Most other tasks can be readily found somewhere, just in different spots.
The upgrade from XP is straight forward, but only personal data can be retained. Everything else has to be set up again.
Windows 7 upgade (for my laptop) kept everything so was very painless.
