Hello, I'm using an openSUSE server with Samba Version 4.1.18-3.33.2-3407 and Windows 7 Professional clients for years without problems. Now I have 5 PC with a freshly installed Windows 10 Professional on it. On the Windows 10 machines I only changed the two registry keys[1] and set up the switch "max protocol = nt1" in "/etc/samba/smb.conf" on the server side. I could join the PDC with the so prepared clients. So far so good. a) But now I can't use the Apps, which are an important part of Windows >= 8. I tried to get some help on administrator.de [2], where I also inserted a picture in the first post. For a long time I thought, I would be the only one with this problem until I found this [3] and this [4] on a dutch page. Especially the video show, what the problem is. b) My other problem/question is the startmenu. It doesn't work. Maybe the reason are wrong excludes in the registry key "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ExcludeProfileDirs". I need to change this due to the reason, that some software saves settings in "C:\User\User\AppData\Local\...". So I need this to be saved to. The clients doesn't make a clean shutdown. If I login with a local account. I can see, the directory "C:\User\User\AppData\Local\TileDataLayer\Database" with some files in it was not deleted. This is supposed to be one possible reason for a not working startmenu. But even to exclude this directory from the profile doesn't help. Can someone please help me out? I invested a lot of days with this problem. I don't like the thought to fail with Windows 10 after I uses Samba for more than 9 years with XP and Windows 7.
