Delate, rename through batch files?

[sidfreed]

Hi all,

So I'm trying to make a personal shortcut on my computer to change a password using the shiftkeys .exe (C:\Windows\System32\sethc.exe) which can be done from setup. I'm looking to design this because I frequently deal with friends and family who have forgotten passwords, as well as my purchasing used computers. I want to automate the process, but I've hit a problem, which is making the batch file remove itself.

Here's the problem. I have a .exe file replace sethc.exe, with sethc.exe renamed to sethc.exe. I'm using the following lines

del sethc.exe
ren sethc2.exe sethc.exe
del %0

The batch file deletes itself successfully (del %0), but it's completely failing at the removal of the .exe and the renaming. I've tried changing the targeting, checking the syntax, but as far as I can tell, everything checks out, yet it still fails.

Any ideas?

Hello Sidfreed, and welcome to Seven Forums.

You might give this a try to see if it may work. If not, also see if right clicking on the BAT file and clicking on "Run as administrator" may.

del /F /S /Q /A sethc.exe
ren sethc2.exe sethc.exe
del %0

Hope this helps,
Shawn

The function of replacing \sethc.exe is interesting; since you can initiate stickykeys on login, you can run the program from login (which means it defaults to running as administrative). Thanks for the help, but for hte sake of learning, what do the options do?

I'll check it out right now.

If you mean the switches in the code given by Shawn, then here you go:

/F Force deleting of read-only files
/S Delete specified files from all subdirectories
/Q Quiet mode, do not ask if ok to delete on global wildcard
/A Selects files to delete based on attributes

Thanks for the code, but I'm still having no luck...

del /F /S /Q /A sethc.exe
ren sethc2.exe sethc.exe
pause
del %0

This is the input I have right now. sethc.exe is never deleted, and hence I think is the reason sethc2.exe is never renamed. when i run the batch.....

...
C:\Windows\system32>del /F /S /Q /A sethc.exe
C:\Windows\System32\sethc.exe

Is the only response I get, i don't see anything else.

Is there something else I'm missing? Most of the command-line work I do is in shell, and I feel like I'm missing something simple.

Sid,

sethc.exe is owned by TrustedInstaller. Have you already taking ownership of the file, and set the file's permissions to "Allow" your user account "Full Control" of the file?

If not, then this is why it's not being deleted.

This must be it, as I've inserted the file through a linux liveUSB. The goal of the script I'm writing is to not leave any fluff, so that I (or the people I'm helping) can run this on their own. Most of the file moving is done within linux, which is why I haven't been getting any results.

However, when running the two commands on an admin command prompt launched normally in windows, it still works; either way, is there a way to set and reset the permissions?

Also, is there a way to use the runas command to bypass the ownership?
