I'm wondering why the background of the PowerShell is different when I open it from Run (or Start) and from the shortcut on desktop PowerShell.exe. In the first case the background is blue, in the latter case it's black.
Are there other differences between the two windows of the PowerShell?
EDIT 2: in the figure below you can see the powershell processes. Moreover, if I open powershell.exe directly from C:\Windows\System32\WindowsPowerShell\v1.0, the background is blue instead of black (remember that its link on desktop opens a black background powershell).
Regarding the below figure, both processes powershell.exe and Windows PowerShell are located in C:\Windows\System32\WindowsPowerShell\v1.0.
P.S.: the situation described here is the same on Windows 10 and 7.
If I go in the folder C:\Windows\System32\WindowsPowerShell\v1.0 and I right click on powershell.exe, there isn't the tab Colours, but its link on Desktop has the tab Colours.
