How to uninstall sensei format? I saw a tutorial on youtube that told something about the sensei format. I was totally unknown to this and wanted to try out what it was. So, I downloaded the addon and installed it, but when I wanted to remove it it won't go. So, I completely uninstalled blender, deleted the whole of the sensei format, even the zip file on my desktop, checked the c drive. And then reinstalled blender from the backup file that I had on my E: and installed it again but When I opened up the file this is the UI:

So getting no way out of it, I just loaded the factory setting and hit CTRL + U, in hope to find that the UI would be the same the next time I open blender, only to be disappointed that the UI is still as above, which was supposed to be like the default like this:

I search through the user preferences to see if the addon was there but it isn't there anymore however blender still remembers it.
How can I revert the changes that I made by my big mistake of installing the sensei format addon?
Besides the Theme I cannot see any difference, so let's fix that. 


hit Ctrl+Alt+U to open User Preferences. 
Go to the "Themes" panel and look at "Presets". Select "Sensei", if it's not there.
Hit the "-" button to get rid of it.
Hit "Restore to Default Theme"
Hit "Save User Settings"
