How to achieve that during an unattended setup of winxp pro

Try using this VB script that another forum member here graciously helped me out with...

Dim SRP, eSRP
Set SRP = GetObject("winmgmts:\\.\root\default:SystemRestore")
eSRP = SRP.disable("D:\")

Replace "D:\" with whatever drive you wish to disable system restore on (you must also keep the quotes).

You can also re-enable it by changing SRP.disable to SRP.enable

You can't use this during the actual installation process, but you can use it during GUIRUNONCE/EX.

Just copy+paste it into notepad and save it with the .vbs extension (making sure not to save it as .vbs.txt)

thanks ... i will go to try it

Or to search through all and turn off except C

Save this as

SysRestoreOff.vbs

Const DriveTypeRemovable = 1
Const DriveTypeFixed = 2
Const DriveTypeNetwork = 3
Const DriveTypeCDROM = 4
Const DriveTypeRAMDisk = 5

Set FSO = CreateObject("Scripting.FileSystemObject")
Set Drives = FSO.Drives
For each Drive in Drives
 If Drive.DriveType = 2 then
  If Drive = "C:" then
  Else
  Target Drive
  End if
 End if
Next

Sub Target(Drive)
  Dim SRP, eSRP
  Set SRP = GetObject("winmgmts:\\.\root\default:SystemRestore")
  eSRP = SRP.disable(Drive & "\")
  Set SRP = Nothing
  Set eSRP = Nothing
End Sub

Set FSO = Nothing
Set Drives = Nothing
