A. There are 2 main methods you can use to create scripts that can be run to automate the updates. The first is to create a .reg file which can then be run using
regedit /s <reg file>
The format of the file is
REGEDIT4
\[<key name>\]
"<value name>"="<value>" a
string value
"<value name>"=hex:<value> a binary value
"<value name>"=dword:<value> a dword value
for example
REGEDIT4
\[HKEY_USERS\.DEFAULT\Control Panel\Desktop\]
"Wallpaper"="E:\\WINNT\\savtech.bmp"
"TileWallpaper"="0"
\[HKEY_USERS\.DEFAULT\Control Panel\Colors\]
"Background"="0 0 0"
Would set the default background and color before anyone logs on.
The second method is to user a Windows 95 style .inf file. These are run using the command
rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 <inf file>
The format of the file is as follows
\[Version\]
Signature = "$Windows NT$"
Provider=%Provider%
\[Strings\]
Provider="SavillTech Ltd"
\[DefaultInstall\]
AddReg = AddReg
DelReg = DelReg
UpdateInis = UpdateInis
\[AddReg\]
\[DelReg\]
\[UpdateInis\]
Below are the keys to be used
| HKCR | HKEY_CLASSES_ROOT |
| HKCU | HKEY_CURRENT_USER |
| HKLM | HKEY_LOCAL_MACHINE |
| HKU | HKEY_USERS |
The file below is an .inf file which performs the same as the .reg file described earlier
\[Version\]
Signature = "$Windows NT$"
\[DefaultInstall\]
AddReg = AddReg
\[AddReg\]
HKU,".DEFAULT\Control Panel\Colors","Background",0000000000,"0
0 0"
HKU,".DEFAULT\Control Panel\Desktop","Wallpaper",0000000000,"E:\WINNT\savtech.bmp"
HKU,".DEFAULT\Control Panel\Desktop","TileWallpaper",0000000000,"1"
INF files can be generated automatically using the SYSDIFF utility if you have a difference file (sysdiff /inf <name of difference file> <dir to create to>)
A registry entry can also be deleted using .REG files. That is, if one has a .reg file with, e.g.,
\[HKEY_CURRENT_USER\Test\]
to enter a key, then one can use
\[-HKEY_CURRENT_USER\Test\]
to remove it.
