Hello
Every day Windows update tries to run a security software update but it keeps getting error code 0xc1900200. Does anyone know what that is and what can be done about it?
Try opening Defender and running the update from there (check for new definitions), once that is done go back to Windows Updates and run it again.. generally this solves the issue..at least for me it did.
Gary I've had to turn Malwarebytes off on two machines to set up Defender and receive the update. When Malwarebytes is enabled Defender works well and alongside of Mambam.
Don't forget to add Malwarebytes Defenders "Allow app through Controled folder access"
