Update Registry Key On First Boot

[Coucher]

I have a need to update a specific registry key with the current date on the first boot of the machine after it is imaged.

Additionally, one issue is that the slashes have to be reversed. For example, if the date is 08/16/2009, the registry key needs to be updated to 08\16\2009.

What I'm visualizing is this:

A bat file of some sort that is set to run once on the first boot.

The bat file would somehow query for the current date, then create a reg file replacing the "/"s with "\"s.

Then execute the merging of the created reg file by invoking REGEDIT.EXE /S importfile.REG


This is just what I'm envisioning. If there's a better way, I'm definitely open to suggestions.

If it matters, this is what the created reg file with the current date would need to look like:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\PGP-IGA]

[HKEY_LOCAL_MACHINE\SOFTWARE\PGP-IGA\PREP]
"INSTALLDATE"="08\16\2009"

Thanks in advance for any help, assistance or advice!

Maybe Something like:

set startDate=%date%
set startTime=%time%

set sdy=%startDate:~10%
set /a sdm=1%startDate:~4,2% - 100
set /a sdd=1%startDate:~7,2% - 100
set /a sth=%startTime:~0,2%
set /a stm=1%startTime:~3,2% - 100
set /a sts=1%startTime:~6,2% - 100

echo %sdm%\%sdd%\%sdy%

I didnt test the echo line, the set lines are copied from a bat file i use on XP. may not work on lower os versions.

and you could append it to a partial .reg file, or echo the whole thing to a temp .reg file
i use it to create a logfile console-%sdy%.%sdm%.%sdd%-%sth%.%stm%.log

from the registry, you'll probably need to run it via cmd.exe (with /c ?) since .bat files arent directly executable

Got it working...

Ended up with:

@ECHO OFF
FOR /F "TOKENS=2-4 DELIMS=/ " %%A IN ('DATE /T') DO (
    REG ADD HKLM\SOFTWARE\PGA-IGA\PREP /V INSTALLDATE /D "%%A\%%B\%%C" /F>NUL)
del %0
