VMware Authorization Service High CPU Usage

When running VMware Workstation on Microsoft Windows, the VMware Authorization Service (vmware-authd.exe) may place a high CPU load on the system.  Upgrading from Workstation 14 to the latest Workstation 15 had no impact, so it's not something that VMware recently fixed.  I remember the issue from many years ago, but not how to resolve the situation.

I'm documenting here so that I don't forget the solution. It's my remind-future-self post.

While I found plenty of Google hits with a similar complaint, I hadn't found any solutions that worked for me.

The vCommunity is great, so a quick tweet was met with a quick reply from buddy Bob Plankers:

Bob's reply sent me to an article on michlG's blog.   The proposed solution did not fit my particular circumstances, but it got me on the right track: looking at Windows performance counters.  

When running PerfMon (I suppose that I should do so more often) I received an error:

My next stop was a Technet article which did the trick:

1. lodctr /r
2. lodctr /q to find anything disabled.
3. lodctr /e:"performance counter" to enable

Windows Registry: Loading and Unloading All User Hives

Today my team was discussing the need to search all user registry hives when scanning for malware.

It's not too bad to do this manually if there are a two user profiles on a system, but it gets considerably more tedious on common-use PCs with more user profiles.  And I'm lazy.

The process might also prove handy for other registry-related tasks, where perhaps can't use Group Policy to be lazy.

Queue Load-UserHives.ps1. This quick-and-dirty PowerShell will search the system for available user profiles and load each key.  Later, you can reverse this with the -Unload switch.  Rather than externally tracking what was loaded prior, a simple naming prefix is used for the unload process.
