使用VBS更新注册表 [英] Update registry using VBS

问题描述

我正在尝试使用VBScript更新PC上的法律标题.到目前为止，我已经能够读取值，但是似乎无法获取它来写入任何值.运行脚本时我没有收到错误，只是没有任何改变.这是我第一次这样做，经验有限；任何见识将不胜感激:

I'm trying to update the legal caption on our PCs using a VBScript. So far, I've been able to read values but I can't seem to get it to write any values. I don't get an error when I run the script, it just doesn't change anything. It's the first time I'm doing this and I have limited experience; any insight would be appreciated:

Dim objShell
Dim strMessage, strWelcome, strWinLogon

' Set the string values
strWelcome = "legalnoticecaption"
strMessage = "did this work"
strWinLogon = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\"

' Create the Shell object
Set wshShell = CreateObject("WScript.Shell")

'Display string Values
Wscript.Echo "key to update: " & strWelcome
Wscript.Echo "key value to enter: " & strMessage
Wscript.Echo "Existing key value: " & wshShell.RegRead(strWinLogon & strWelcome)


' the crucial command in this script - rewrite the registry
wshShell.RegWrite strWinLogon & strWelcome, strMessage, "REG_SZ"

' Did it work?
Wscript.Echo "new key value: " & wshShell.RegRead(strWinLogon & strWelcome)

set wshShell = Nothing

注意:这些是目前的测试值.

NOTE: These are testing values at the moment.

推荐答案

您的脚本似乎没有错误.但是，由cscript 28416995.vbs启动会返回下一个错误(其中22 = WshShell.RegWrite行):

Your script seems to be bug-less. However, launched by cscript 28416995.vbs returns next error (where 22 = WshShell.RegWrite line):

28416995.vbs(22，1)WshShell.RegWrite:注册表项"HKLM \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ System \ legalnoticecaption"中的无效根.

28416995.vbs(22, 1) WshShell.RegWrite: Invalid root in registry key "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\legalnoticecaption".

这不是无效的根，类似于访问被拒绝，而是因为写入HKLM需要提升的特权(或以管理员身份运行)

It's not invalid root, it's something like access denied rather because writing to HKLM requires elevated privileges (or run as administrator).

注意:

• 您应同时更改LegalNoticeText值和LegalNoticeCaption值.
• 在HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\注册表项下，两个值也都存在.在这种情况下(如果计算机未连接到域或禁用了组策略)应该在下一个脚本中工作.

• You should change LegalNoticeText value together with LegalNoticeCaption one.
• Under the HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ registry key there both values reside as well. For this case (if a computer is not connected to a domain or with group policy disabled) should work next script.

以管理员身份运行:

option explicit
On Error Goto 0
Dim wshShell
Dim strResult, strMessage, strWelcome, strWinLogon, strWinLog_2, strWinLTxt
strResult=Wscript.ScriptName

' Set the string values
strWinLTxt = "legalnoticetext"
strWelcome = "legalnoticecaption"
strMessage = "did this work"

strWinLogon = "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\"
strWinLog_2 = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\"

' Create the Shell object
Set wshShell = CreateObject("WScript.Shell")

'Display string Values
' continue execution if requested registry values not present 
On Error Resume Next
strResult = strResult & vbNewLine & "Existing Caption Policies: " _
  & wshShell.RegRead(strWinLog_2 & strWelcome)
strResult = strResult & vbNewLine & "Existing Text Policies: " _
  & wshShell.RegRead(strWinLog_2 & strWinLTxt)
On Error Goto 0
strResult = strResult & vbNewLine & "Existing Caption Winlogon: " _
  & wshShell.RegRead(strWinLogon & strWelcome)
strResult = strResult & vbNewLine & "Existing Text Winlogon: " _
  & wshShell.RegRead(strWinLogon & strWinLTxt)
strResult = strResult & vbNewLine
strResult = strResult & vbNewLine & "key to update: " & strWelcome
strResult = strResult & vbNewLine & "key value to enter: " & strMessage


' the crucial command in this script - rewrite the registry
wshShell.RegWrite strWinLogon & strWelcome, strMessage, "REG_SZ"
wshShell.RegWrite strWinLogon & strWinLTxt, UCase( strMessage), "REG_SZ"

' Did it work?
strResult = strResult & vbNewLine
strResult = strResult & vbNewLine _
  & "new key Capt. value: " & wshShell.RegRead(strWinLogon & strWelcome)
strResult = strResult & vbNewLine _
  & "new key Text value: " & wshShell.RegRead(strWinLogon & strWinLTxt)
Wscript.Echo strResult 
set wshShell = Nothing
