I installed Windows Server 2012 R2 Datacenter on my Sony VGN-Z56TG laptop. After I finished installing it, I noticed that some features in Windows 8.1 were missing from it, and some other limitations. Examples:
- I cannot connect to Wi-Fi networks.
- I cannot sign in with a Microsoft account.
- I cannot decorate the Start screen or change the system colors.
- The Store is not available. Attempting to launch Internet Explorer Modern merely launches the desktop version.
- The operating system did not detect the proper resolution for my laptop screen and is not letting me change it from 1024x768. Also, I can't change the screen brightness from the brightest, wasting my battery life when not plugged in. Additionally, it hurts my eyes, and I have to switch to High Contrast Black to minimize the effects.
(As I said above, the limitations presented here are examples. There are more limitations besides the five that I listed here.)
How can I enable features like those in Windows Server 2012 R2? In other words, how do I sort of "combine" the UI functionality of Windows 8.1 with the server functionality of Windows Server 2012 R2 Datacenter? I would prefer to do it without a third party tool, because I am a little afraid of installing unnecessary stuff (including adware) on the system.
Update: I did the things suggested in the comments and the answer and solved the first problem of not being able to connect to Wi-Fi networks, and partially fixed the third problem of not being able to change the system colors, but I still can't decorate the Start screen. The second problem seems solvable to me by changing a Group Policy setting. I also partially solved the fourth problem of not having the Store, but I get an error that says that I can't use the Store with the default Administrator account when I try to use it, which I think I can solve by creating another account. However, (as far as I know) the Store requires you to sign in with a Microsoft account, so I still can't use the Store due to the second limitation even though I've managed to install the Store. The Internet Explorer Modern tile on the Start screen is still launching the desktop version.
