Windows 10: Activation error after uninstalling an windows update

After I uninstalled the latest windows update on my laptop, I frequently recieve activate windows message and the watermark. Before windows update, it was absolutely fine. How can I fix this?

I uninstalled the update because of black screen error

Who has seen this vista update error

When you go to Windows vista update and it tell you to update a driver that you have already updated. Then it says failed to update and gives you the error code that tell you that you already have a never version than that. WTF? Why in the world would it be trying to updated something with an older driver. Well the only way to get it out of your windows update list is to go uninstall what ever that driver is then run the update and install it. Then run the newer drivers again.

Well I still can't get the Nivida Network Bridge to disappear out of the list. I uninstall the one in device manager and go to the update and before it's even done with that. Vista is automatically installing a newer version than is in the Vista update list.......

 

Windows 10 will not activate Error code 0x803F7001

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
