Just a quick FYI on a KB article we recently published for VMM 2012 R2. After you install Update Rollup 7 or Update Rollup 8 for System Center 2012 R2 Virtual Machine Manager (VMM 2012 R2), you may see the following error message when you attempt to open the VMM admin console:

Console Add-ins Warnings and Errors
The following warnings and errors were encountered while loading console add-ins.
Your personal add-ins folder is editable by users other than yourself and the administrators group. This presents a potential security risk by which users could cause malicious code to be executed using your credentials. Please check the following folder and remove any permissions assigned to other users:
"C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\bin\AddInPipeline\Addins\Domain_User"

Note that this issue occurs only when there's a console add-in applied to Virtual Machine Manager. This error message can safely be ignored, however if you’d like to keep the error from occurring there’s a workaround in the following Knowledge Base article:

3138680 - Error when you open the VMM console after you install UR7 or UR8 for VMM 2012 R2 ( https://support.microsoft.com/en-us/kb/3138680 )

I too have seen the same error and was disappointed to see the KB article gone.
