YNQ Adds Server/Client SMBv3 Capabilities to WinCE
The SMB protocol version 1 was introduced in Windows CE version 5.0 in 2004. Microsoft kept supporting the SMB protocol in Windows Embedded Compact until 2013 without upgrading it to incorporate later SMB protocols – namely SMB2 and SMB3.
The outdated versions of Windows CE are still in use today mainly in the industrial world, in manufacturing and automation, sensors and monitoring devices, controllers, ATMs, gas and fluid system components, energy and utilities. Due to the nature of these industries, an upgrade to a new operating system is impractical as would require huge efforts and costly resources. These constraints prevent outdated Windows CE-based machines from connecting to network shares on Windows machines running SMB version 2 or later.

The table above shows what the most recent SMB dialect supported by each Windows version is. The SMB version used between an SMB client and an SMB server will be the highest dialect supported by both. A WinCE machine will enforce the usage of SMBv1, which is disabled by default in recent operating systems (see the article Bid Goodbye to Malware Prone SMBv1).
