this software works! but there is bit of problem when it makes boot.ini file. you have to change the boot drive from 0 to 1 or 1 to 0 depending on whats there by default
BTW Microsoft is going to end support for WINDOWS XP thats why they are making it prone to attacks day by day also if you notice anti-virus nowadays dont tend to work anymore on Windows XP (efficiently) than on WINDOWS 7. And reason I have told you. In my opinion you better stick on to Windows 7, download and install from a genuine ISO and either crack it or use original key for activation , it will work like a charm.
If you processor supports EMT64 than go for Windows 7 64BIT else stick to 32BIT.
