Did you already test right clicking on the BAT file and clicking on "Run as administrator"?

"Run as administrator" could clear event viewer logs successfully.
But, double click couldn't let the BAT run goto noadmin.

You'll need to use "Run as administrator" per the steps for it to successfully run.

Something you have set is making the BAT think you are already elevated and not using "goto noadmin" when you just double click.

I created a new "normal user" account just now.
I double clicked the BAT, it still not run goto noadmin.

That's OK. But it was funny that your test could appear goto noadmin.
What difference of our OS?

Thanks you a lot finally.

I'm not sure other than different language possibly being an issue with the command.

I changed the code since UTF-8 to ANSI.
The BAT still not run goto noadmin.

I downloaded and applied English US language pack of Windows 10.
After I double clicked the BAT, the BAT ran goto noadmin finally.
I was so sorry that I made you so busy.

Finally, I wanted to said that I hated language pack bug.

Best regards,
Steven.

Hello,

Yes, it should still work in Windows 11.

BTW...I've been using this .bat utility for quite some time now. But I went a couple of steps further with the .bat file: I found "BAT to EXE Converter (64 Bit)" online, and converted it to a .exe file. Then I set the file's compatibility to "run as administrator". All I have to do do now is click it on my desktop and it runs. Hope this helps!

Although a very handy utility, some antivirus programs, including Windows Defender, sometimes identify such .exe files as viruses and delete them!
Have that in mind too!
