Windows 7/2008/2008 R2 Won’t boot after installation of KB4512506 / KB4512486 / KB4512476

After installation of these update, you can have problem booting you server. with this warning:

The digital signature for this file couldn’t be verified.
file:\windows\system32\winload.efi status 0xc0000428

You can fix it by booting you windows operation on the installation disc, and go to a Recovery command prompt and type these commands:

c:\> bcdedit

This screenshot is taken from a running Windows Server, in a recovery boot the identifier under the second Windows Boot Loader, will be named {default} instead of {current} 

c:\> bcdedit -set {default} -nointegritychecks 1

Replace {default} with the one from the bcdedit output.

Normal this have been resolved by installation and updated version of KB4474419, but there have not been an updated version to Windows server 2008 yet.
But to Windows 7 and Windows server 2008 R2, you can download an updated version here:

If you want to change Mapi, Autodiscover / EWS / OAB / OWA / ECP / Activesync Url, this is how it works

Example you have bought a certificate on you external name, and now you got certificate warnings in outlook.

set-MapiVirtualDirectory -id "SERVERNAME\mapi (Default Web Site)" -internalurl https://owa.domain.prefix/mapi -externalurl https://owa.domain.prefix/mapi

Set-WebServicesVirtualDirectory -Identity "SERVERNAME\EWS (Default Web Site)" -InternalUrl https://owa.domain.prefix/EWS/Exchange.asmx -externalurl https://owa.domain.prefix /EWS/Exchange.asmx -BasicAuthentication:$true

Set-AutoDiscoverVirtualDirectory -Identity "SERVERNAME\Autodiscover (Default Web Site)" -internalurl https://owa.domain.prefix/autodiscover/autodiscover.xml -externalurl https://owa.domain.prefix/autodiscover/autodiscover.xml 

set-OabVirtualDirectory -identity "SERVERNAME\OAB (Default Web Site)" -internalurl https://owa.domain.prefix/OAB -externalurl https://owa.domain.prefix/OAB 

set-EcpVirtualDirectory -identity "SERVERNAME\ecp (Default Web Site)" -internalurl https://owa.domain.prefix/ecp -externalurl https://owa.domain.prefix/ecp

set-OwaVirtualDirectory -identity "SERVERNAME\owa (Default Web Site)" -internalurl https://owa.domain.prefix/owa -externalurl https://owa.domain.prefix/owa 

set-ActiveSyncVirtualDirectory  -identity "SERVERNAME\Microsoft-Server-ActiveSync (Default Web Site)" -internalurl https://owa.domain.prefix/Microsoft-Server-ActiveSync -externalurl https://owa.domain.prefix/Microsoft-Server-ActiveSync

Set-ClientAccessServer -Identity "SERVERNAME" –AutoDiscoverServiceInternalUri https://owa.domain.prefix/autodiscover/autodiscover.xml  

iisreset

 Or if this is a single server installation you can do it like this: (Or if you want all servers to use the same URL
