Windows 10: Unable to reactivate Windows 10

After having Blue Screen problems I uninstalled Windows 10 from my laptop & immediately reinstalled it. Everything is fine now however I got a message to Activate it in settings. It states @ 'couldn't reactivate Windows 10, Error Code 0x800705B4'. Troubleshoot was no help. Went to Activate Windows Now which said basically my new copy was not genuine - even though I did a straight uninstall / reinstall on the computer, not via any third party which is annoying. When I pressed the Change Product Key a window came up for me to enter the 25 character product key. I attempted to put my original product key in but it just ghosted and would not allow me to enter anything. Underneath stated @ The last product key you entered (my new one) can't be used on this copy of Windows ( 0x800705B4), Can somebody here please tell me what the issue is as I cannot see where I have gone wrong and what problems there may be if I cannot activate Windows. I am able to change other things in Settings and everything else is working fine. ( FYI only the last 3 digits of the Product Key is different from the original one ).

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
