Can I change my Windows 7 product key at a later date?

Can I change my Windows 7 product key at a later date?

I am currently downloading Win 7 home premium from MSDN, which I intend to try out on a Vista PC that is in dire need of a clean install. However, I have also pre-ordered a copy of Win 7 home premium which will arrive in October and is intended for that PC. I am wondering if I can install the one I download from MSDN today and update it to use the new key in October without the need of a reinstall. I found this blog post which seems to suggest that it is possible to change keys in Win 7.

"You can change product keys for like SKUs. If you're downloading the RETAIL (as opposed to Volume License) version of Windows 7 Home Premium from MSDN, and you have purchased the RETAIL version of Windows 7 Home Premium, then (usually) yes, you can change the product key. I say usually, because there have been some products that know they are the MSDN version and will not use a ""regular"" retail key. I doubt Windows 7 is one of these (I'm downloading it now as well, so I do not yet know).

Not sure how the E version will play a role, but I suspect it will not work as it is not a product you can upgrade to. Update: the E version has been cancelled, so this scenario is no longer an issue.

In any event, take backups. If it doesn't work, install the new copy you have purchased and restore your backups."

I'm running the Ultimate version of the release candidate, and on the system properties dialog, at the bottom where it displays the activation status and product ID there is a link to change it. I don't know about Home versions, but I believe I recall seeing that link on my wife's laptop which was running vista home premium before I upgraded it.
