Solution:
Go to this folder:
C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application\UI\CMS\ActiveX

Open the EPiServerClientComponents.CAB file and extract the contents.

Run a cmd prompt as administrator and enter:
cd “C:\Program Files (x86)\EPiServer\CMS\6.1.379.0\Application\UI\CMS\ActiveX”
– or wherever you extracted the files

regsvr32.exe EPiFileUpload.dll (install fileupload)
regsvr32.exe EPiOfficeIntegration.dll (install office integration)

Reconnect a network share with credentials on Windows 8 login

Such as the WD MyCloud network disk…

Create a .bat file and enter this:
net use Z: \\192.168.0.2\Document mysecretpassword /user:MyUserName /persistent:yes

Replace text in bold.

Add a shortcut to the bat file to the Startup folder:
C:\Users\[MyUserName]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
Set the shortcut to run in “minimized window” to avoid showing the window.
