If the CUE software is not removed completely it has drivers installed that causes Windows to still have the locking freezing issues. My problematic K55 was not fixed from this until I removed unistalled completely the CUE software and disabled the HID devices. Just having the software closed and set to not auto-run with Windows will not fix the issue as it will still attempt to run some services. I have since purchased a non Corsair branded keyboard but keep check to see if they have ever resolved this issue. I considered a different model Cosair but thought the odds where too great it would also suffer the same fates on my system. My system is new not even a year old yet so this problem seems to be widespread and affects all types and ages of motherboards.
