Barty1884 :
Where did you see these files?
You can create an ISO of an XP install disk (with later SPs), but the subsequent updates etc still need to be done via Windows Update.
Anywhere you see offering Vista, XP or 7 beyond the main 'service packs' are not legit sources of installation media and may well have malicious content baked in.
I saw these examples:
-(Windows 7, 8.1 and 10) 44 in one iso
-(Windows 7 and 8.1) 29 in one iso
-(Windows Vista x86 and x64) all in one iso
Windows XP doesn't have "install.wim" file. Can I do it without "install.wim" file ?
