This problem is not related to any git configuration nor repository, it's related with the Program Gith Bash and the OS Windows 10
It began once I installed and customized Git Bash on my Windows profile, it never appeared the Git icon on the toolbar, which was bothering me. So I start to go after some ways to fix it. (reinstalling never worked)
In an attempt to erase all customizations I made on Git Bash I deleted everything related to Git from the Windows Registry Editor, which at the time I thought would solve the problem but only made it worse.
Now I can't even start my Git Bash, it's sort of useless, and none of the modifications I made was undone.
When I install Git and try to open the Bash it shows with the visual customizations I made + the following message.
