DU Meter versions

v7.2 [Nov 9, 2016]
Windows 10 compatibility is improved: since Windows 10 Anniversary Update, only Microsoft-signed drivers are accepted on fresh installs of Windows 10, if Secure Boot is enabled. DU Meter 7.20 includes such Microsoft-signed drivers, and thus the issue of DU Meter not working on fresh installs of Windows 10 is resolved.
DU Meter works on Windows Server 2016. Windows Server 2016 GA release currently accepts "attestation-signed" device drivers, even in Secure Boot mode (same as Windows 10). There is very little information available about the actual Microsoft policy for device driver signing on this platform. Although DU Meter works fine on Windows 2016 right now, we'll monitor the situation closely and issue an update if/when required.
No changes in Windows 7, 8, 8.1, Windows Server 2008 and Windows Server 2012 support: these operating systems are supported as long as all Windows updates are installed.
Windows Vista and Windows Server 2003 are no longer supported. There are certain changes in the way DU Meter files are digitally signed, which were necessary to fully support Windows 10 Anniversary Update and Windows Server 2016, and these changes are potentially incompatible with Windows Vista and Windows Server 2003 (it depends on installed service packs and other patches). While DU Meter might still run OK there, we no longer offer support or test DU Meter on these older versions of Windows.

v7.1 [Nov 20, 2015]
This release addresses several rare issues with outgoing traffic monitoring, and has an improved installer for better compatibility with Windows 10. Several cosmetic and localization issues were addressed as well. If you have already bought DU Meter 7 license, this update is free, and can be installed on top of your currently installed version. No need to uninstall.

v6.4 [Nov 14, 2014]
November 13, 2014 :: DU Meter 6.40 has been released.
This update includes several important bug fixes:
Security update: OpenSSL libraries used by DU Meter for secure email communication have been updated to the latest version, due to security bugs discovered in previos versions.
Security update: DU Meter executables have been signed with IEEE Taggant security certificates to prevent rare antivirus false positive reports.
Rare memory leak problem has been fixed.
Automatic error reporting and recovery has been enhanced to report possible memory leaks and application hangs.
Installer has been improved to install and uninstall in silent mode correctly.
Several additional minor bugs and typos have been fixed.

v6.2 [Oct 24, 2012]
