Windows 7: Did I have 32 bit or 64 bit?

Did I have 32 bit or 64 bit?

I replaced a hard drive for someone and need to reload the OS. It had 7 Home Premium. I don't know if it was 32bit or 64bit. I do have the product key from the sticker. How would one find out which version it is?

There's probably a way to tell from the PID but my list doesn't show it. How much memory is installed? That would be hint. 4GB and above most likely had x64.

Two things, one is to boot to a 64-bit version of the disc, if the computer is only 32-bit it won't install [the 32-bit version will install on 64-bit hardware]. If it does install and you get the Product Key typed in, it will either accept it or not. Either way nothing lost, just do it differently.

Unfortunately, 3GB RAM will work with either version.

@Berton - Just curious but how do you tell a 32-bit PC from a 64-bit PC when there's no OS installed?

I have both 32-bit and 64-bit LiveDVD discs for Linux, whichever one will boot I can run directly from that disc. I start with the 64-bit version, if it boots I go with it. If it doesn't boot I try the 32-bit version.

Does the old hard drive still work ?
If it does, can you connect it to another PC and see what is on it ?

Are there any System Backup Images stored on an external device such as a USB drive ?
If there are, can you browse an image to see what's in it ?

If you can't determine what the OS was, with 3 GB of RAM i would use 32 Bit.
The Win 7 license is good for 32 Bit and 64 Bit.

As to David's question, there's a clue on the HDD if you can read it. Both versions will have a Program Files Folder but the 64-bit version will also include a Program Files (x86) Folder where 32-bit programs get installed.

What would keep the 64-bit from loading on an empty or new PC? I'm still confused.

I have never tried but I think if the PC is not 64 bit capable (cpu and motherboard) Windows 7/64 will not install and for sure will not work.

Some one who has tried please correct me if I'm wrong.
