How to set single bit in ShellState to disable Recycle Bin delete conf

[runner3734]

The title pretty much says it all. I would like to have the recycle bin delete confirmation option turned off. I know that this is determined via the ShellState entry at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer.

With delete confirmation enabled, my shellstate is:

"ShellState"=hex:24,00,00,00,2e,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,\

01,00,00,00,0d,00,00,00,00,00,00,00,00,00,00,00

With delete confirmation disabled, my shellstate is:

"ShellState"=hex:24,00,00,00,2a,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,\

01,00,00,00,0d,00,00,00,00,00,00,00,00,00,00,00

since hex e = binary 1110 and hex a = binary 1010, it is clear that enabling or disabling the delete confirmation is just setting a single bit in the shellstate key.

I see in other threads, recommendations to use a regfile entry that overwrites the entire shellstate key. This seems very dumb to me, since we don't know what all the other bits do, and we want to make an unattended install that will work on many different computers. Obviously, we want to leave all the other bits alone, so that we only affect the delete confirmation setting.

Is there an easy way to do registry value bitsetting for unattended installs?

Regfind.exe from the Win2k resource kit features general search and replace support on the registry/hive files...

regfind /?

usage: REGFIND [-h hivefile hiveroot | -w Win95 Directory | -m

\\machinename]

[-i n] [-o outputWidth]

[-p RegistryKeyPath] [-z | -t DataType] [-b | -B] [-y] [-n]

[searchString [-r ReplacementString]]

Maybe usefull to you...

The way I've done single bit changes in the past was to retrieve the original value at runtime, then have the script calculate the result of adding the retrieved value + the single bit, then write that sum back to the registry. I haven't done it with the Recycle Bin confirm bit, but I have done it with other values before, and it works.

You can make this change using a simple inf file:

[Version]
Signature	= "$Windows NT$"

[DefaultInstall]
BitReg		= Bin.Set

[Bin.Set]
HKCU,Software\Microsoft\Windows\CurrentVersion\Explorer,ShellState,,0x04,4
