IMPORTANT! Paragon Driver Security Patch for All Products of Hard Disk Manager Product Line (Biontdrv.sys)

Several products based on Paragon Hard Disk Manager include a system driver BioNTdrv.sys (version 1.3.0 or 1.5.1) which must be updated until February 28, 2025 in order to comply with changed Microsoft security guidelines and to exclude any security risk related to the presence of the old driver version.

We have released a fixed version (2.0.0) of the BioNTdrv.sys driver which is included in new program updates (17.45.0) of all current editions of Paragon Hard Disk Manager 17. If you have already a license of a product based on Paragon Hard Disk Manager in the new customer portal (LC) Paragon Licensing Center, you'll find the new update under "Products -> My Products".

Older versions of products based on Paragon Hard Disk Manager can be updated by installing the Paragon Driver Security Patch.

After February 28, 2025 several features of Paragon Hard Disk Manager won't be available if the fixed version of the of the BioNTdrv.sys driver is not installed.

The fixed version of the of the BioNTdrv.sys driver cannot be installed under Windows 7-8.1 resp. Windows Server 20008 R2-2012 due to Microsoft's driver signature policy. (But these OS aren't safe anyway.)

Older versions of Paragon Hard Disk Manager (14 or older) don't support Windows 10+ resp. Server 2016+.
