Although Microsoft discontinued support for XP on April 8th, 2014 you may still want to upgrade to a faster system. As a side note as of early July of 2014 Windows XP still has a market share of about 25% or 1 in every 4 computers which includes Windows, Linux or a Mac OS, not bad for a retail version of an Operating System that hasn’t been sold in more than 6 years.
The latest motherboards and processors do not support XP, not even the Pentium 4 Anniversary edition (socket 1150, G3280 processor) just released in July of 2014 may not support XP as the X97 Intel Chipset only supports Windows 7 and 8. A few older socket 1150 boards may support XP but may not support a G3280 processor unless the motherboard manufacture wants to put the time and effort in upgrading the BIOS to support the latest processors. The irony of it all is that for many years Intel Pentiums and Windows XP went hand in hand on store bought or home built computers. I wonder just how much sales an anniversary edit of XP to complement Intel’s Pentium anniversary processor would generate!
In my case I have thousands of dollars tied up in software and a high precision scanner for 35mm slides, negatives and photos. Yes there is a Windows 7 driver and software for the scanner but some of the features I need are missing. In addition the software includes targets and color calibration utilities that are not cheap. For the record, this PC is not connected to the Internet.
I solved my problem by upgrading my old Pentium 4 3.06GHz Northwood processor, 2GB of DDR memory and some old ATA/IDE drives to an Intel socket 775 E6700 Dual core processor, 4GB of DDR2 memory, SATA-II hard drives, better graphics card and a motherboard that has the necessary Intel chipset and XP device driver support. The end result is that the performance is much improved and I saved myself a lot of money as upgrading or replacing the software was not necessary.
