How to make AX Server work after Upgrading From Windows 8.x to Windows 10

This article illustrate how to make AX Server work after Upgrading From Windows 8 to Windows 10

Recently I have updated my Windows 8 to Windows 10. then I realized that I cannot start neither of my AOS (AX 2012)
Service is still in place. If you tried to start e.g. AX 2012 AOS you would encounter the following errors:
Object Server 01: Error accessing registry: Cannot open key SYSTEM\CurrentControlSet\Services\Dynamics Server\6.0\01. Error code: 0 
Object Server 01: The directory "C:\WINDOWS\system32\\bin" does not exist or access to it has been denied by the operating system.
Object Server 01: The home directory for Axapta (C:\WINDOWS\system32\) does not match the required structure or can not be accessed. Please check installation, configuration and access rights.
If you tried to open AX Server Configuration Utility you would see it completely empty:

The problem is that registry keys located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dynamics Server\ were deleted during the update.

Proactive solution
If you have not updated yet when the best solution would be to export that node and import after update


Solution
Note: Provided solution works for AX 2012 R3 version.
But if you have already updated and facing this issue then you have the following options:

• Recreate keys manually;
• Import from your colleague;
• Create the reg file yourself by copying and pasting the contents below.

AOS uninstall or repair won't work for this.
For your convenience below is the exported AX 2012  registry keys for Original (installed configuration). Copy the text to notepad, save as reg file and import using regedit.
Do not forget to change the flowing info before importing:

1. AOS instance name
2. DB Server Name
3. DB Name
4. Ports (TCP/IP, WSDL and netTCP) defaults 2712, 8101, 8201.
5. User running the AOS service.
6. Configuration name (optional)

Restart your computer after importing (otherwise you won't see changes in AX Server Configuration Utility.
