It is 32-bit because there is only 2gb memory, which does not make sense to install/run 64-bit windows on.
No, if you upgrade to pro (as I have done), the original key is maintained. You would need (as I have done) to keep the upgrade key for future use.
No, you have only a 32-bit license.
Did you upgrade via the Microsoft online store? if so, did they basically send a key to input in tot he SYSTEM to change the version, was this email or printed on the screen?
I have to upgrade a number of client machines, am trying to avoid imputing email addresses.
I purchased retail boxes of Windows 10 pro, which came with a usb stick and a key. The stick is worthless (since it is usually out of date), but not the key. Make a new stick from the Microsoft download site, if you want a stick.
But, with the key, you just go to start, settings, update&security, activation, and change product key. Then, sit back, and watch the blinking lights.
I resolved issue with Key by purchasing one directly from MS Store on the compute Stick. I did have to use the standard open MS Digital license key to complete activation to switch OS over to Pro version.
Adding to Al's statement, it makes absolutely no sense to install 64-bit Windows if you don't have more than 4GB of DRAM. It's bad enough that a significant chunk of the available DRAM is lost to device and firmware support; compounding it with the larger DRAM requirements of the 64-bit environment just doesn't make sense.
We have not heard back from you, so we will close this inquiry. If you need further assistance, please post a new question.
