Re-enroll devices in Intune

How to join a lost device in Intune?
Recently I had to Factory Reset a Laptop and rename it.
The "old" device was still in Azure AD as "Azure AD registered" , Intune still showed it as Windows Device enrolled. The first thing what comes in mind is: delete. That is what I did. Does it work ? No.
I tried to re-enroll my new renamed and factory reset Windows Laptop in Intune with the Company Portal App and got the error message: Device is already enrolled
After some research I endet up on a Microsoft Website, where one suggestion was to delete some GUID registry keys. I am always reluctant to delete any registry keys on a Windows device, but my desperation turned into a hopeful action: to delete all GUIDs under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Enrollments Note: Make sure to NOT delete Context, Ownership, Status and ValidNodePaths.
After a restart I could successfully join the Intune World.
