No real slow WU scan problems seen on my dad’s Toshiba based Win8.1 laptop, woody.
Saw this quote from MS support KB article 3172605:
“Known issues in this update
Issue 1
Symptom
After you install KB 3133977, the software for Intel Bluetooth devices may not be fully functional because of existing software issues in the Intel Bluetooth driver software. These issues may affect Bluetooth keyboards, mice, audio streaming devices, and voice headsets. You may also not be able to pair new Bluetooth devices. Intel is currently working on an update to address their software incompatibilities.”
Installing “KB3133977” breaks Intel bluetooth devices?
