Windows 10: I can't seem to activate windows

I recently upgraded my PC from a 7600k based system to 3700x. Due to this I had to change motherboard, Ram and PSU as well (my old PSU did not provide enough Power). Now I can't activate Windows. I had Norwegian Windows 10 home. I chose to install it in English this time after checking the forums here and finding information about the License not being Language specific.
Here is what I tried:
1. click activate Windows.
2. get an error Message and troubleshoot
3. Click "I changed hardware on this Device recently"
4. Choose the Device I am currently using (formerly msi mobo, now asus).
5. Click activate
6. Get the Message: Unable to activate Windows.
We can't reactivate Windows on this Device. Try again later.

You can also activate this Device by going to the store and purchasing a genuine copy of Windows.
Go to store.


I have no idea what else I should do. I clicked on the learn more link, and it basically told me to link my installation With my account, which I have done in the past. This is not my first time clean installing, but in the past I always did it without changing parts.

What should I do to get Windows? It is my primary PC and I don't currently afford a New key. I could of course change back to the old parts and then reactivate, but if I do that, I am stuck With my pc being too slow.

Taskbar bug: switching to another window -will not appear at the front


Follow either of these steps to fix the issue with the Active window hiding behind.

Method 1:
I suggest you to disable window by hovering over it with the mouse and check if it helps. To do so I suggest you to try the below given steps and check if it helps:

1. Press Windows key + X key and click on Control Panel.
2. Select or click Ease of Access.
3. Click or tap onEase of Access Centre.
4. Click on Make the Mouse Easier to Use was uncheck Activate Window by hovering over it with the mouse.
5. Check if issue is resolved.

Method 2:
I would suggest you to completely uninstall the touchpad driver and reinstall it. Kindly follow the below given steps.

1. Press “Windows key + X” and click on “Device Manager”.
2. In the list of devices, you should see the touchpad drivers.
3. Right click on the device and then select "Uninstall".
4. In the uninstall dialog, make sure you select the option to delete the driver package from the system. This causes the driver package installed earlier to be deleted.
5. In the Action menu of Device manager, select “Scan for Hardware changes” option. This will cause the device driver to be reinstalled. Once the driver is installed, close all windows and restart the computer.
