To really make certain programs load MUCH faster, you install yourself a nice Ram disk.
Install those programs to the ram disk. Set the ram disk to loadup automatically at boot time.
Things like firefox load instantly. Things like photoshop load very fast, not quite instantly.
It does take longer to boot, but I normally run my pc 24/7.
That can be setup to automatically start the ram disk, and load the installed files to the ram disk, from the hard disk.
No need to reinstall, windows expects the software to be on drive Z or whatever. It loads up automatically. Works nicely.
