Permanent Variable On Bootup

Is there a way to setup a permanent variable for that session of the PE like %systemroot% example

if I run this

Code: [Select]

set TagFile=\laddsbootUSB.tag

For %%I in (C D E F G H I J K L M N O P Q R S T U V W X Y Z A B) do (dir %%I:\ 1>nul 2>nul && if /i exist %%I:%TagFile% set LaddsUSB=%%I:)

%LaddsUSB%\

How do I make the LaddsUSB variable permanent for that PE session like systemroot? I dont want to have to define this in every script after my main variable setup script has run at bootup

Code: [Select]

For %%I in (C D E F G H I J K L M N O P Q R S T U V W X Y Z A B) do (dir %%I:\ 1>nul 2>nul && if /i exist %%I:%TagFile% set LaddsUSB=%%I:)   

Of course I realize once I restart the PE, I would lose the variable but thats why I have my autorun command to reset it or would it be easier just to use SETLOCAL to pass the variable to the next script?

Yes

like %systemroot% example

Well not a good example .....  , %temp% is a better example 

I guess adding 3 more lines to your batch will do the task
(2nd line to assure in case....)

Code: [Select]

reg.exe add "HKCU\Environment" /v LaddsUSB /t REG_SZ /f /d "%LaddsUSB%"
Set LaddsUSB=%LaddsUSB%
BroadcastEnvChange.exe

and enable Win7PESE\Tweaks\"ImDisk Ramdisk" on your test

Let us know how it goes....


ps: btw, you can make small builds for faster virtual tests by deselecting most default things.... ;)

Well well,
you do not need above "with scripts", neither Win7PESE nor Gena ,
both projects have "Run From CD" option, available on scripts,
So all you need to do is, selecting this option on scripts..... 

There are also some more options/methods for scripts (aiming same tasks, different / flexible methods ;)) .....
as far as you well define what you are trying to achive .......


what you are after (adding a Hot Environmental variable) is more valuable than scripts,
 but for your own customized portabilation on disk (ufd, usb etc..)..
Which I may guess, after / IF you well organise, we can put to projects too 

Will BroadcastEnvChange.exe change my temp directory? I need temp to stay B: so this may be more what I need?

Code: [Select]

reg.exe add "HKCU\Environment" /v LaddsUSB /t REG_SZ /f /d "%LaddsUSB%"

This worked perfectly

Code: [Select]

set TagFile=\laddsbootUSB.tag

For %%I in (C D E F G H I J K L M N O P Q R S T U V W X Y Z A B) do (dir %%I:\ 1>nul 2>nul && if /i exist %%I:%TagFile% set LaddsUSB=%%I:)

reg.exe add "HKCU\Environment" /v LaddsUSB /t REG_SZ /f /d "%LaddsUSB%"

Helpful as usually! Thanks 


I just realized how conceded I must seem, using my name and all in my bootstuff!
