I was wondering if windows 10 will install as 32 bit or 64 bit, because one of my computers has a x64 processor with 32 bit windows 7 on it, but I want it to install 64 bit windows 10, will it already do that? Thanks!

    You cannot upgrade a Windows 7 or Windows 8.1 Update x86 installation to Windows 10 x64 installation. If you want to do that you will have to first upgrade your installation, then using the x64 .ISO, install Windows 10 x64 and perform a clean install. Doing this will wipe all your personal files so perform a backup before you do it. – Ramhound Jul 29 '15 at 14:59

    If you're talking about the Free Upgrade offer, it will be upgrading your existing OS, so it will not change the bit-ness of the OS. – heavyd Jul 29 '15 at 14:59

According to This article, the OS will upgrade as 32-bit. After successful install, you will be able to do a clean install of the 64-bit OS.

This is confirmed by a few Technet articles etc which I have read, however I havent been able to test this in the real world though as all my kit is already 64-bit.

  • This has been the case since there has been an in-place upgrade process. You have never been able to upgrade a x86 installation to a x64 installation. This is technically true with Linux, although in that case, given enough skill it can be done. – Ramhound Jul 29 '15 at 15:10
