What to do if your SmartSDR DAX Drivers Puke or Get Scrambled by a Windows Update?

I've done a mashup of the various threads, support articles, downloadable manuals and information on sorting out the DAX issues when Windows wrecks your DAX infrastructure updating.

I segmented what I could find into three levels of fix - Simple Renaming, DAX removal/reinstall and SmartSDR Removal/Reinstall including DAX.

Also tried to capture the various cautions community members and FRS team members have suggested.

I'm running through the drill myself on a PC where Windows did its DAX mess-up tricks, and figured once I gathered everything I could find that I should share back my personal summary.

Appreciate suggestions on improving the mashup.

YMMV of course and the information is what I found was current as of 17 Jan. 2019 for SmartSDR 2.4.9

Thanks for this Steve.
Regarding; "I'm running through the drill myself on a PC where Windows did its DAX mess-up tricks",
  I suspect that before MickeySoft {tm} improves their quality, we will have plenty of use for this document,
and plenty of time to test and revise it's content.

Cheers,

List of possible additions;

1.  Mention Windows 10  Microphone permissions change, 
      found at the bottom of this post;

2.  Consider posting the chart of CORRECT DAX driver names, shown in this post;
https://community.flexradio.com/flexradio/topics/dax-drivers-after-windows-update-or-smartdsr-update

3.  DAX Driver Graphic:   There is a great graphic showing Before/After;

which is  most of the way down this post;
https://community.flexradio.com/flexradio/topics/windows-10-update-vs-dax-new-problem-crash

Those might be really helpful additions.   You might even consider
making your article a PDF or linked Word Doc on your site, so others
could print it?   Just an idea.

Cheers,

Neal

When you’re depending on a computer, especially a Windows computer, it extremely important to periodically backup the computer with point in time image backups. Acronis is backup software that allows you to take point in time image backups.

If you run into problems in the future, you can recover your computer back to s point in time when the computer system used to work properly. It’s important to do periodic backups, such as once a month, or more frequently. Keep several different backup points in time. It’s also a good idea to backup to the cloud as well as local. The cloud backup will allow you to recover to a different computer if your computer is stolen or distroyed in a fire.

If the computer is recovered to a known good point in time, and the Flex radio still doesn’t work properly. Then you know that the problem is most likely the Flex radio, not the computer.

Image backups are very important, since you depend on your computer, and you need to be able to be prepared to fix computer problem. The Microsoft backup software is a poor choice. I tested Microsoft backup software for years. The Microsoft backup software appears to backup the computers, but usually fails to recover the computers when you do test recoveries.

Most people fail to backup their computers. Yet the same people would probably not drive around with an empty gas tank and no spare tire.

I'll incorporate some of the ideas emailed to me and the additional references shortly.

The neat script Neal N6YFM posted is a great idea to make things more approachable.

Thank you for suggestions, additions!

I'm also thinking that there might be a way I can create a sub-page off my Flex-6000 Software page to make the mashup into a sort of sticky.  

BTW, If your browser has a "Reader View" option you end up with a pretty nice printable version of my posting.

Updated 20 Jan 19 to offer a simplified DAX removal & replacement set of directions.  

Or at least directions that make sense to the way I think.

YMMV but it fixed my situation easily.

I'm looking through other suggested edits to see how to cherry pick the useful parts while not muddying the waters with links to stuff I couldn't get to work without some tinkering.
