Windows 7 x86 and x64 keys?

Question

Windows

Do the Windows 7 keys (those on the sticker) fit from the x86 version to x64? If not, how is it cheaper and easier to upgrade the system to x64? Or will I have to buy a new license?

Answer 1

The OEM version of Windows 7 includes only the bitness version that comes with the laptop, and only that version is licensed - either 32-bit or 64-bit. A 32-bit OEM key will not work with a 64-bit OEM, and vice versa.
It's been discussed here , here and here .

Answer 2

Well, when buying Windows, there is no division into x86 and x64, so everything should work. And if not, write to microsoft support.

Answer 3

Do the Windows 7 keys (those on the sticker) fit from the x86 version to x64?

Yes.

Those. if the x86 version came with the laptop, then I can easily install x64 from the MSDN image and it eats the key and activates?

Most probably not. If the laptop is with OEM Windows, then most likely there will be no manufacturer's SLP certificates in the MSDN image; put something you put it, but you can not activate it. Until you add certificates to Windows. At least that's how it was on Vista . I haven’t rearranged the OEM sevens yet, but I suspect that it will be necessary to act as on whist - look for the keys and sew them into Windows, after that it will be possible to activate the key from the sticker.

Answer 4

Just checked.
A freshly purchased (more precisely, a year or two packed) OEM Win7prof x86 license came up when installing Win7prof x64 and was successfully activated afterwards.
It is possible that when reinstalling, there are other rules, but there is nothing to check now.
