Well, despite my adamant claims to the contrary, looks like my old desktop has received yet another stay of execution. I have been having an issue with removing my external HD. I kept getting a message that I could not remove it safely because another program was using it. Did a little research and discovered my problem could be caused by the Windows file indexing program. Reading some more, I discovered my old desktop would probably be much snappier without it. Since I never search for a file, I decided to disable indexing on both internal and external drives. WOW, what a difference!
My old (12 +/- years) HP a1600n is slow as molasses compared to a modern rig, but it now seems like a new machine to me.
If you have an old desktop and do not often search for files, you should consider disabling the Windows file indexing program.
