Cumulative Update KB4056892 Windows 10 v1709 Build 16299.192

The update has now just appeared for me. I have backups in place and so we will see......

Had two KB's 4056892 and 4058702. The latter is not shown in view installed updates but, is shown in uninstall updates. No info on that KB on MS's website, update catalogue say's critical and the file size is approx 13Mb.


I take it that you all have this KB.

No, only i3 7100 :)

Nothing showing here even after a manual update check.

I've benchmarked a very CPU intense application I use for reference by timing it running to completion during a couple of different tasks. Be interesting to compare. I'll also do a before and after winsat test, although I don't know if that will show any differences or not.

All installed. This is on a Dell Vostro laptop with i5 processor and 4Gb RAM and SSD.

My two files ran as follows.

Before update.
File 1 took 15.5 seconds
File 2 took 25 seconds.

After update.
File 1 took 16 seconds
File 2 took 25 seconds.

Conclusion here is no obvious performance hit.

WinSAT tests. This is before and after. Again I would say no statistical evidence saying performance is impacted. Some things are fractionally better, some fractionally worse.

Ive not seen 4058702 come through on our machines. Wonder what this was?

Yes, it's happening on some processors with kernel leak bug.
Intel is trying to develop new chipset driver to fix the issue.
