I'm running Windows 10 (1803)

If I try to run any msc (I.e. Device Manager) directly (by searching for "Device Manager" and clicking the find result) I get the error ...

Error

However, if I open cmd with "Run as administrator", I can open it normally with devmgmt.msc. This system is not on a domain. This account is in the admin group.

Logging in with a different account with admin permissions results in the same error.

I'm not sure where to check, or what to correct. Advice?

This problem occurs when Windows can't confirm that the certificates used by the operating system are valid.

Check the date/time of your computer, and that you are not using a pre-relase or an Insider Windows Build. You can start winver.exe that no expiration date is displayed.

If you use an official build and the date/time is correct, you can use this command (as administrator): SFC /Scannow so that Windows can check if the system files are corrupted.

Additionally, check if you can find interesting informations by clicking on the "Show information about the publisher's certificate" link.

    Your mention of the certificate was the clue. It turns out the cryptsvc was disabled. I re-enabled it, and the issue went away. Thanks for the help! – BurningKrome May 02 '19 at 06:31
