Windows 10: Problems activating windows 10

My windows does not seem to be activated. So I get my key from command prompt, paste the key into settings and press activate.


It then comes up with the message:


Unable to activate windows.


Something interrupted our troubleshooting. Make sure that you are connected to the internet, wait a few minutes and try again. (0x80070002)


I am connected to the internet, so something must be wrong. I go to the troubleshooter, and it only gives me the option to upgrade my edition of windows (I am on Windows 10 Home). I then click that and press start, it then comes up with the exact same message:


Unable to activate windows.


Something interrupted our troubleshooting. Make sure that you are connected to the internet, wait a few minutes and try again. (0x80070002).


I am on a Dell Inspiron 7559 and the warranty has expired.


If someone can please help that would be appreciated.

Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.

 

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
