Computer: HP EliteBook 8540p
HP Protect Tools Security Manager v5.07.711
OS: Windows 7 64bit
Fingerprint Sensor: Validity Sensors, Inc.
Fingerprint Sensor Driver: 22.214.171.124
Affected application: Microsoft SQL Server Management Studio 2008 (v10.0.4000.0)
I have been having critical performance problems with Management Studio 2008. Affected functionality of the program particularly includes grid draw, file open/load, and text find. Performance of this program has been so bad, it has affected my ability
to do my job. For example, it can take a full minute sometimes to return less than a hundred rows from a small lookup table and draw the result set to a grid. This is not acceptable.
I finally found the reason: it's the "Biometric Authentication Service" a.k.a. DpHostW.exe. This utility service application came packaged with my company-supplied HP laptop, it supports the use of the built-in hardware fingerprint sensor.
I have disabled DpHostW.exe and I have regained full performance of SQL Server Management Studio, but I'd really like to continue to use my fingerprint sensor as well, if possible.
