Windows 10: Can't Activate. Can I downgrade from Pro to Home without reinstall?

I had some hardware issues and had to completely clear my hard drives, clean the disks, etc. I used an install disk for Windows 10. Apparently, I had forgotten which version I used to have and chose the Windows 10 Pro version. That was apparently wrong, as I was trying to figure things out with the Troubleshooting Assistant. They had me sign in to my Microsoft account and after checking, they said that I previously had the Windows 10 Home version.


Long story summed up, is there any other way to fix this? I don't mind using my entitled previously owned version, but do I **HAVE** to re-install everything?? I guess my biggest question is, is there an app I can do this through? And if not, what is the best way to perform that task???


Thanks in advance for your help!

Downgrade Windows 10 enterprise to Pro

Hi Sumit,

Thanks for your quick response and help, But I was told that if I inserted the Windows 10 Pro product key into the activation section it will be downgraded automatically like the following steps:

1. Open the Settings app and click Update & Security.
2. Open Activation and click Change product key.
3. Enter your Windows 10 Professional product key and click Next.
4. Restart the computer after the new product key is activated.

Can this be helpful ?

 

Usable Product Keys for Enterprise downgrade to Pro


Hello wetenhr, and welcome to Ten Forums.

You could downgrade to Windows 10 Pro using the generic key under step 1. You'll still be using the same version that you currently have installed, but you will be able to update to the latest version and build via Windows Update.

When it's finished downgrading, you could try to activate Windows 10 Pro with your Windows 7 Pro or Ultimate key. If unsuccessful, you may need to purchase a Windows 10 Pro key from the Store to use to activate with.

 

Downgrade Windows 10 Enterprise to Windows 10 Pro  


Hey Peter,

As long as you have a W10 Pro license linked to your MSA for that PC, you would be able to use the generic key under step 1 to downgrade from Enterprise to Pro, then let it automatically activate Pro with your digital license.
