My computer is unable to complete the two updates listed above and comes up with installation error code 0x800706ba and 0x800706be. Since it has been trying to do these two updates I am unable to access any of my Microsoft apps. Edge opens for a few seconds and closes down and outlook says it will try to open in safe mode but doesn't. I need my computer to work and I need to access these apps for work. Please help???
