Group policies not applied after upgrading to Windows 10

Question

After signing in on my T430 the group policies delivered by the AD-server are not applied. In particular the network drives don't get mapped (there are some other policies as well, but that's the bigggest problem). When i wait for some minutes in order to force a group policies update, the network drives are slowly getting mapped. The network connection works after signing in and the connection to the server is stable. I set up a clean Windows 10 installation on my T430 (instead of before just upgrading from Windows 8.1) and without installing any third party programs oder drivers and I experience exactly the same problem. On 6 other desktop-computers Windows 10 works fine, just our 2 upgraded Lenovos don't apply the group policies after signing in. I restored my Windows 8.1 image and now it works fine again, the group policies are applied after signing in. Has anyone else experienced this problem yet and found a solution for this?

I have contacted Lenovo via phone support. They told me Windows 10 isn't tested yet, they have not made any experiences so far and in order to that officially don't support Windows 10. Drivers may work, may not work. Contrary to this list - https://support.lenovo.com/us/en/documents/ht103535 We don't use any wmi filters. But what troubles me ist that at the first login of a user all group policies are applied, including mapped network drives. So everything is fine. But all further logins make it not work. I have contacted Microsoft at well, they tell me to contact Lenovo. Lenovo on the other hand tells me to contact Microsoft...
