Copying Windows product keys
Copying Windows product keys
You should avoid using outdated OEM keys since they won't function properly. It's important to note that legally, you can't transfer these keys to another device. One possible workaround is installing Windows 7 or 8 on your new computer and then upgrading later, though I'm not certain if free upgrades to Windows 10 are still available. For the safest approach, purchasing a Windows 10 license is strongly advised.
Set up Win7 or 8 first, then move to Win10, unless you need it on a completely different machine where that’s not possible.
You may continue to use them by reaching out to MS Support, who will provide you with an ISO compatible with the key.
It sounds like you're describing a frustrating experience with long wait times and unhelpful interactions. No worries—I totally get that!
