That’s 9 different DVDs if you want all Windows 7 versions to hand. Instead of doing that Microsoft released each version as a separate disk and each of those has a separate 32-bit and 64-bit DVD. Only the Starter edition of Windows 7 does not have a 64-bit version.īoth 32-bit and 64-bit editions of the 5 available consumer Windows 7 versions all easily fit on a single layer DVD. Windows 7 is available in both 32-bit (x86) and 64-bit (圆4) editions and has Home Basic, Home Premium, Professional, Ultimate and Enterprise versions. Even after that Windows 7 is still by far the most widely used Windows operating system. Windows 10 has been out for a while now and it was offered as a free upgrade to Windows 7 and 8 users for the first year.
