Since Windows 10 Anniversary Update (1607), it became possible to disable the MAX_PATH limit on the Windows operation system level without using prefix \\?. By default, this feature is disabled.
To enable the built-in support for long paths in Windows 10/Windows Server 2016, use the Regedit.exe editor to set the LongPathsEnabled parameter of REG_DWORD in the registry key HKLM\SYSTEM\CurrentControlSet\ControlFileSystem with a value 1.
You can change this registry parameter with the following PowerShell command:
Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\ControlFileSystem -Name LongPathsEnabled -Value 1
Or you can enable long path support via Group Policy Editor (Win + R gpedit.msc) Computer Configuration > Administrative Templates > System > Filesystem. Enable the policy Enable NTFS long paths.
