Virtual Com port creating BSOD on: January 02, 2018, 10:03:16 PM
Good Afternoon,

In our environment we are using Windows 10 Education the Creators Update. We have keypads that use Eltima Software that create virtual serial com ports for our USB connections. These ports use the evserial7 driver.  The computer will generate a BSOD and reboot due to a bugcheck for this driver. Please see details below:
