When I hit start and type "Active", for example, the start menu correctly finds "Active Directory Users and Computers", "Active Directory Domains and Trusts", etc. on Windows 10 and Windows 2012R2.
that is NOT the case in Windows 2016 TP5. I have to type in "administrative" to get to "Windows Administrative Tools" and then run my mmc.

I don't know if it is a setting I should enable (maybe Cortana), or I have to wait for some indexing to finish (I've already waited waaay to long; besides Windows 2012R2 does not have this index-wait-time) for this comprehensive search to happen, but now the search function on start menu of Windows 2016 TP5 does not return all the relevant results as it does in other previous versions.

I am working on a new lockdown group policy that will be used for our future Windows 2016 XenApp servers.

As this will be used for a lot of users, certain things will need to be locked down. For example the Settings need to be locked down in the same way as it possible with Control Panel.

I want to be able to manage what settings is visible in Settings with GPO.

We cannot allow users on a shared RDSH server to install windows update, add VPN connection, check what application is installed etc etc.
With Control Panel it was possible to hide certain settings, with Settings its all or nothing.

First, I have been supporting Microsft since Win 3.1 and NT 3.1, I am stating I am one of your longtime engineers and hope you will take my suggestion into consideration.

As an Administrator I access a lot of different areas that users do not. These areas are critical to my day to day oerations and help me keep your products in a good light. Recently, you have removed the control panel and our work arounds get removed with each update. As an engineer I realize that these tools are totally unecessary for the standard user, but critical to me.

What I am asking as a near 30 year supporter\administrator\engineer, is that you consider making a custom GUI install for engineers. One that keeps our tools where we need them at and are used to. Speed and accuracy are very crucial, and when you all move these tools around to make things look pretty and exciting for end users, it makes life horrific for us.

A great example was a few years back when I worked on my first server 2012 I was at a clients office with an emergency and the shutdown restart was hidden in charms. I looked like a complete idiot that I could not figure out how to shutdown or restart the server. I had to pull the power plug, real professional. We lost that client due to that situation.

With these tools there are some fine tuning and updating that also needs to be addressed. A great example is the DHCP panel, everytime I have opened this tool in all my years it never remembers its settings, and although you have a single or AD integrated DHCP server I have to manually pick and connect to it. The I have to strectch all the areas out appropriatly to be able to use the tool. There are other applications that are the same way and it would be nice to have them updated also.

What I am trying to be nice about is I along with many of my era engineers would like for Microsoft to acknowledge our importance and to work with us to be able to provide the best support we can. Evertime you move, take away or change our tools you cripple us, and that cripples your reputation.

Please take a minute to work with us, your life long dedicated engineers that promote and support your many servers OS'/Application and desktops OS's. I have given you almost 30 years, please work with me/us to make our lives easier and our users and mangement far more happy with your products.

Thanks
Matt
