Once the leaked handle count reaches a certain threshold, smart card based operations fail with error with SCARD_E_NO_SERVICE

Key="HKEY_LOCAL_MACHINE"Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat"

Type="REG_DWORD”

Data="0x00000000”

Symptom
After installing this update, SMB servers may experience a memory leak.
