I have a SFX zip with files and a batch inside that auto-starts after extraction. The batch starts by attempting to elevate priviliges to the batch using the get admin code below.

Works fine, have used it for a long time. But now I need it to do something extra.

The SFX, upon execution, caches the files in C:WindowsTemp. Some of the files are sensitive in content, used during the remainder of the batch file processes to set up installations, copy files etc. At the end of the batch file, the files are deleted.

However, it dawned on me that if a user presses no at the UAC prompt, the batch doesn’t run so the files remain in the cache!

I decided to try and insert the file deletion in the admin code after the user presses no.
But because that part is windows shell, I cant see a way to capture that they pressed no.

"%SystemRoot%%winSysFolder%WScript.exe" "%vbsGetPrivileges%" %*
DEL file1.txt
DEL file2.txt
DEL file3.txt
exit /b

"%SystemRoot%%winSysFolder%WScript.exe" "%vbsGetPrivileges%" %*
 exit /b
 DEL file1.txt
 DEL file2.txt
 DEL file3.txt

After a long time trying having the extra lines in various places I got close to trying them before and after the exit /b. However it still deletes the files if you press YES.

I also tried removing the exit /b so it carries on running the admin code and triggering the deletion because admin wasn’t gained, I expected that ELEV wouln’t resolve at the end so tried this.

"%SystemRoot%%winSysFolder%WScript.exe" "%vbsGetPrivileges%" %*
:gotPrivileges
setlocal & cd /d %~dp0
if '%1'=='' (del "%vbsGetPrivileges%" 1>nul 2>nul  &  shift /1
    DEL file1.txt
    DEL file2.txt
    DEL file3.txt
)

I know some might comment that even if this can be done, cancelling the batch mid way through will leave the files there. Yes, but at least this is something, and I need to see if, how I can do this now.

Utlimately I need the admin code to not immediatley shutdown if the user presses no so it can delete the 3 files in the cache, THEN closing.
I thought it would be easy but hours later I need to call upon the experts once again. Thanks for any advice in advance.
