How to set X-BOX 360-controller as gaming device 1?

Hello.
After cleaninstall windows 10, I have got a strange problem with my USB X-BOX 360-controller. If I plug it in right after boot, it shows as device 1, but if I use the mouse or have attached my G29 wheel (and de-attached it again), then when I connect my X-BOX 360-controller it now has no 2 or 3 (randomly), and therefore the settings in my games must be changed every time. This was not a problem before this cleaninstall.

Do I need a new driver for my X-BOX 360-controller? Or is there a setting in windows 10 that always can give X-BOX 360-controller no1 (as long as it is the only gamedevice connected).

I have tried different ports and different USB 2 and USB 3, but ONLY if connected right after boot it will get the no 1. (this no can be seen on the X-BOX 360-controller as a little green line at no 1, 2, 3 or 4) I only have the driver build into windows 10, as there was no driver CD along the controller when I got it.

As I got no answers on this, I think my English was not good enough, so I'll try to refrase it.
On the controller there is 4 green fields in a circle, showing 1, 2, 3, 4 (for player device 1, 2, 3, and 4). And after the cleaninstall (see post #0), my controller connect as "player 2" or "player 3", if I don't connect it right after boot. I want it to connect as "player 1", and it does so if conected right after (or before) boot, but not after I have used any other gaming device, including my mouse!!.

So how do I change the setting for the XBOX controller to "player 1"?
All I can think off myself is a reboot, but there must be another (and faster) way to do this.
