Jag hittade en post på ett forum som gjorde så att det löste mitt problem iallafall!
Here goes:
1. Press: Windows-button (the one between lAlt and lCtrl) + R, a window should pop up.
2. Write: "services.msc" (without the ") then press enter.
3. In the list of services, scroll down to "UPnP Device Host", click it and press "Stop service".
4. Now do the same thing but with the service "SSDP Discovery".
5. Exit the window and go to control panel-> Network and Internet-> Network and Sharing Centre-> Change advanced sharing settings (to the left)-> Under "network discovery" select to turn off network discovery.
6. SAVE CHANGES
Det funkade direkt efter jag ändrade!
