Microsoft updated the TechNet article on roaming profiles yesterday. The updated information states that Windows 10 Anniversary Update will use a .v6 extension to distinguish itself from other operating system versions of the profile. This allows your roaming or mandatory profile to operate on different operating systems without conflicts.
| Operating system version | Roaming User Profile location |
|---|---|
| Windows XP and Windows Server 2003 | \\<servername>\<fileshare>\<username> |
| Windows Vista and Windows Server 2008 | \\<servername>\<fileshare>\<username>.V2 |
| Windows 7 and Windows Server 2008 R2 | \\<servername>\<fileshare>\<username>.V2 |
| Windows 8 and Windows Server 2012 | \\<servername>\<fileshare>\<username>.V3 (after the software update and registry key are applied) \\<servername>\<fileshare>\<username>.V2 (before the software update and registry key are applied) |
| Windows 8.1 and Windows Server 2012 R2 | \\<servername>\<fileshare>\<username>.V4 (after the software update and registry key are applied)
\\<servername>\<fileshare>\<username>.V2 (before the software update and registry key are applied) |
| Windows 10 | \\<servername>\<fileshare>\<username>.V5 |
| Windows 10 Anniversary Edition | \\<servername>\<fileshare>\<username>.V6 |
Unlike with Windows 8 and Windows 8.1, the .v6 extension will work immediately and does not require a Windows Update to be installed nor an entry in the Registry. Beyond that simple but important change, the TechNet article stayed the same and can be read for further details. With this information, we can continue to follow the previous ‘Mandatory Profiles with Windows 8.1 Update‘ article here on 404TS though mandatory profiles on Windows 10 have proven stubborn.
