Windows 10 Reverted to 64 bit?

[Macmaster2000]

I recently did a clean install of Windows 10 Pro 64 bit and I am sure that I did the 64 bit as that is the one I downloaded and made a flash drive of. But when I installed the November update that came out a few days ago, the System page in the Control Panel now says that it is a 32 bit install.
I noticed it while trying to install 64 bit software. And since it is 32 bit, only 2.48 of the 8 GB of ram I have installed is usable.
Before anyone asks, yes it was 64 bit, this isn't the first time I have used this flash drive, and I do have a 64 bit processor.
The person with the windows tech chat had no idea, just spurted completely unrelated stuff.
I believe that the latest November update might have something to do with it, but I have no idea.
If need be, I guess I can do a clean install, but I'd really rather not.
Does anyone have a clue what has happened??

It's literally impossible. There is no path to 'upgrade' 32 bit to 64 bit or vice versa. The only way to get it on is a clean install.

Even if you suffered a bug in the upgrade, if the upgrade did not force a clean install then you had 32 bit the whole time.

I know that its impossible, that's the whole reason that I posted this. I don't know how it happened, but I DID have 64 windows. I've got Autodesk Maya not starting because it is a 64 bit install, and it doesn't work anymore.

Your install disk was 32bit. That's the only way. Easy to download the wrong ISO. As every app is totally different it's not possible to switch. As mentioned, that really is impossible.

I'm going to guess you updated via the media creation tool rather than waiting for the windows update stuff to happen. Then, you accidentally clicked the wrong image (32 bit). You should be able to fix it by just running another update with a 64-bit image (which will take you back to pre TH2 update unless/until they fix the issue the ISO's were pulled for) and then just let the windows update process get you to current.
