Windows 10 Certificate Expired (Windows Update)

[worldwidetuna]

Windows defender and windows update, cer. expired.
Non of the Windows apps are working , so i have uninstalled most of them , using PowerShell admin.
In my opinion, most Microsoft stock apps are useless, so no big deal.
However, the same can not be said for the Windows Defender. When getting updated regulary , is the far superior to any anti_virus +malware app out there.
I was not successful fixing the issue, by using PowerShell, or by tweaking the Registry.
I have , however exported the expired Certificates to NotTrusted cer. folder . Not so sure what to do, Any tips are welcome
Thanks on reading

is this an activated or unactivated copy of Windows... I assume the later but just so we are clear about account types
