A little more than a week ago I made the terrible mistake of running
sc delete AudioEndpointBuilder in the Windows command line.
The consequences were truly disastrous.
I have no sound in my computer any more! How can I undo this
apparently dangerous command?
A naïve attempt to just plainly run sc create AudioEndpointBuilder
did not fix the problem.
Here are some suggestions.
cmd file at:After unzipping, right-click it and choose Run as administrator.
If you ever get the question Overwrite (Yes/No)?, then I recommend
that you always type n (for No) and hit Enter,
because answering Yes means that you will overwrite the backup file
that was supposed to make it possible to undo the changes in the
registry – in case that is something you would want to do.
The content of the script is as follows:

If the above script does not restore the sound in your computer, there
might be problems with the file AudioEndpointBuilder.dll and/or
with audiosrv.dll.
Those two files are usually located in C:\Windows\System32\.
They could be missing or have the wrong version(s) compared to your
current build of Windows 10.
However, unless you have messed with these files, this is likely
not to be the problem.
Another reason why the script does not get your sound back could be
problems with your sound drivers.
But I consider this to be unlikely also.
In Device Manager look for Sound, video and game controllers.
The easiest way to install the latest available drivers might be to
let Windows Update do it for you.
You can try upgrading to a later build of Windows 10.
This is similar in effect to making a clean install of Windows 10.
On my laptop with an HDD drive, this took about seven hours.
See for example:
Automatic Upgrade to New Windows 10 Feature Update
How to Force Windows 10 to Install an Update
Or make an online search, for example for :
"Windows 10" "Update & Security" "Update Assistant".
Hit Win ⊞+R, type cmd, hold down
Ctrl+Shift and hit Enter.
1
Then run :
DISM /Online /Cleanup-Image /RestoreHealth
1 Holding down Ctrl+Shift opens the command prompt as administrator.
