Computer came with 32-bit, can I use the "Key" for 64-bit install?

Hi, my Toshiba laptop came with win 7 32 bit with 2 GB of ram. I upgraded the ram to 4 GB and I know with the 32 bit it will only use around 2 GB of ram. I want to install 64 bit. Can I use the key on the bottom of my laptop for a 64 bit installation?

Yes, you can use the product key as it is edition but not bit version specific. A normal retail box for instance contains both 32 and 64 bit installation DVDs but only one product key. it's then up to user to deicde which bit version he wants to install, the product key is the same.

By the way, a 32-bit Windows can use about 3.2 to 3.5 GB.

Since your system came with an OEM version of Windows, the key it is currently running under cannot be used for a new installation (unless you have a Toshiba installation disc for 64bit). You can, however, use the key on the COA sticker that is on the bottom of your laptop.

The 32bit version should use about 3.25GB of your RAM. If not, something is wrong. Don't expect a lot more performance from a 64bit version. It will be marginal.

Here is a very good tutorial that will give you guidance:

I still use 32 bit on 4gb or less RAM. But a Clean Reinstall will always be better than the factory install so go ahead an try it to see. You may want to try both.

If you have a retail key, yes. If you have an OEM key, you have to use the key from the COA sticker that is on your PC.

I never needed to download an iso. But other people from here have downloaded from this site. I think it is legit. Have not heard any complaints.
