The solution is very easy to adjust the maximum memory under Windows, it works from Windows 7 and Windows 10/8.1!
Please run the command msconfig via the Windows command prompt [Windows + R] then click on the BOT tab. Select the operating system (in this case Windows 8.1) then click Advanced options.
In the Windows Advanced options activate maximum memory and customize setting! PS: That stated in MB (mega bytes).
Now just waiting for OK and the system reboot!
After restarting Windows, only the preset memory is used, in this case, 4 Giga-Byte!
