OOOOOOOOH! Finally I've installed Win LongHorn on my pc! It looks great and is stable enough (for the moment, it never crashed and seems to run fast)! I've encountered lots of problems during setup because the installer is a bit stupid and didn't load my drivers from floppy only because they're in a folder and not in the root....So I created another floppy with drivers in the root and it worked. The installation worked good, but when was nearly finished, the setup said that it was corrupted and I have had to reinstall windows from the beginning. The second time all worked correctly (even if before the installation started, the setup blocked 2 or 3 times...) and now I've Win LongHorn installed. I thought to see more news from xp, but the work of microsoft looks good. Now the problem is that lots of application doesn't run under this new os. I tryed the program compatibility wizard, wich looks useful, cause lets setups of old programs to run, but, e.g. in the case of Mcafee AntiVirus, after the installation I've not succeded to let it run normally, cause it always say me that the os is unrecognized.... So, They have still much things to do, but they are at a good point
