Windows Service Corrupted

And how to fix it….

So recently, I came across a Windows 10 workstation that was able to get online, but would not access any network resources, file shares or printer shares.

After a few minutes of checking system logs for errors, I happened to notice that the Workstation service would not start, and that the startup string for the service had been truncated, and now looked something like this:

Simulation of original error as displayed by services.

Note, the startup string for it should look like this:

I ran system file checker, which identified and corrected corrupt files – note in 20 years, this is the first time I’ve seen SFC actually report a problem. Alas, as expected, this did not resolve the issue.

To correct the problem, I had to invoke Powershell with administrative rights, and then run the following command to restore the service to an operational state:

sc.exe config lanmanworkstation binPath= “C:\WINDOWS\System32\svchost.exe -k NetworkService -p”

High Sierra Expose Bug

So this has been making me crazy for awhile, and I haven’t come across a solution for it online yet… Every now and again, I’ll accidentally swipe up with three fingers on my 2015 MBP running High Sierra, and Expose will animate half way through and stop. Then I have no keyboard or touchpad, and my only recourse is to hard boot the system, which really sucks!

UPDATE: Further testing shows that when the the display changes, keyboard commands do not function until the transition is completed. Using three fingers, you can slide up or down on the trackpad to complete the transition from one app window to many and back. When the transition is completed, the keyboard responds. I tend to see this on web pages that have a lot of animated or interactive objects on the top window. While scrolling, control can shift focus to the object, a picture or video, and interrupt the action of scrolling down. This can sometimes result in the end user accidentally activating Expose. Yeah, that would be me.
