Hello,
I work in the IT dept at my company and we recently purchased 25 Lenovo X1 Carbons as our standard laptop (replacing the Dell 5470 series). Unfortunately we've been having issues that are causing audio static & dropouts, mouse 'jerkiness', WiFi dropping, and other weird problems. We've been trying to fix this for several weeks and haven't been able to come up with anything or get any help from Lenovo.
We've used a tool called LatencyMon and are seeing a lot of issues with wdf01000.sys. We've tried just about everything that we can think of. So far:

We've used a tool called LatencyMon and are seeing a lot of issues with wdf01000.sys. We've tried just about everything that we can think of. So far:
- Re-imaged several test machines using Lenovo repair tool
- We see this on machines right out of the box, and fully updated with most recent drivers & upgraded to Windows 1709 Fall Creators Update
- Updated BIOS
- Tried changing every BIOS setting we thought was relevant to performance/tweaking
- Tried updating drivers directly from vendors
- Xperf's don't show anything different or specific but we can re-run new ones
- We have a few HP Elitebook 840's and ~150 Dell 5470's with same specs (core i5, 256 ssd, 8gb memory) and we're not seeing these same performance issues
