Title: NEED A REGEDIT VARIABLE FOR THE DRIVE LETTER THAT THE OS IS INSTALLED ONTO..??
Post by: gumbaz on August 20, 2007, 03:16:36 AM

IS THERE A VARIABLE I CAN USE WHEN I MAKE A REG FILE THAT SPECIFIES THE DRIVE LETTER THAT THE OS IS INSTALLED ONTO..

SOMETHING LIKE THIS:

Code: [Select]

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"SYSTEM"="%SYSTEMDRIVE%\\SYSTEM\\SYSTEM.EXE"

BUT THE VARIABLE %SYSTEMDRIVE% REPRESENTS THE DRIVE LETTER THAT THE OS IS INSTALLED ONTO..
IS THERE ANYTHING LIKE THIS THAT I CAN USE...??

what, you mean a variable like %systemdrive% ?

You surely know how to list all the system variables, why not do that on your own machine, and see if there is one that might be what you are looking for?

I just manually entered in the reg entries from the regedit..
I tried both   %SystemDrive%\batch.exe   and   %HOMEDRIVE%\batch.exe
and they never startup the C:\batch.exe file when i log off and back on or Restart the PC..??
the batch.exe files code is just

Code: [Select]

start calcand calc never opens so what am i doing wrong, or will those variables just not work in regedit..??

No, system variables don't work in Regedit.

You could write and run the regedit file from batch using the %systemdrive% variable though.

>>"file.reg" echo "system"="%systemdrive%\blahblahvirustostart"

I wasn't. Files that alter the registry are curious things to write for a hobby, aren't they?
