Windows 10: Windows 10: bat files not being run when double clicked

Hi,

somethings has been changed in my win10 64b pro (Microsoft Windows [Version 10.0.17763.134]) box, and now I have issues with bat files:

When I double click on them, I get a cmd, empty that shows up for a couple of seconds, and then closes. The .bat is NOT run
Of I open a cmd can cd to the dir containing the .bat, and I type the first letters of the .bat, TAB does not complete the file name, it does complete filenames of exe files.

If I run the .bat from the cmd I opened in 2., it DOES run fine
I have checked "assoc .bat" and "ftype batfile" and both return expected values.
Any insight would be super useful...

:)

 

Double-click to run .bat - Windows cannot find file


Recently (seemingly out of nowhere) my Windows 10 PC stopped running .bat files when I double-click on them. If I right-click and "Run as administrator" the files run. If I open a command prompt and invoke the bat file it also runs. This is true for every bat file I have tried in all of the different folders and drives I have tried.

For example, I created Test.bat in M:\Downloads\. The content of this file is just one command "pause".
This is the error message I get when double-clicking the file in explorer:




Right-click and "Run as administrator":




And from a command prompt:




I have tried the following:
1. File Association Fixer
2. Checked the system environment variable COMSPEC. It is correct: %SystemRoot%\system32\cmd.exe.
3. sfc /scannow - the result was "Verification 100% complete. Windows Resource Protection did not find any integrity violations."

Any ideas?

 

Double-click to run .bat - Windows cannot find file


Not uncommon, apparently:
Double Clicking Batch File Windows cannot find file - Super User

I tried one logged in as a standard user - location not in system path- worked ok when double clicked.
Here's how to reset it if associated with e.g. Notepad (which isn't your problem, but for interest)
- and note 'batfix' - which may be similar to the one from the Tutorial:
Cant run .bat (Batch Files)

 

Double-click to run .bat or .cmd - "Windows cannot find..." the bat/cmd file.
