如何使用NSIS检测Windows更新（或KB更新）是否已安装？

Question

To execute my windows application, windows machine needs some pre-installed windows update(Like KB2999226 - I need to check this update). I need to install this updates with my application installer silently using NSIS.

How to check windows has already installed particular update using NSIS.

I have tried this NSIS-Windows_Critical_Updates_Mass_Installer but its not working. It's not able to check pre-installed update.

My windows application will run on Windows 7 SP1 and later version and windows server 2012 and later version. So i need to check updates in all this versions.

To check whether KB update is installed or not using NSIS I have used below code:

section

clearerrors
nsExec::ExecToStack 'cmd /Q /C "%SYSTEMROOT%\System32\wbem\wmic.exe qfe get hotfixid | %SYSTEMROOT%\System32\findstr.exe "^KB2999226""'
Pop $0 ; return value (it always 0 even if an error occured)
Pop $1 ; command output
detailprint $0
detailprint $1

To install update(.msu file) I have used below code.

section

clearerrors
Strcpy $strInstallPath "$temp\Updates\KB2937592-x86.msu"
Push "$temp\RunMSU.Bat"
Strcpy $0 "$temp\RunMSU.Bat"
FileOpen $0 $0 w #open file
FileSeek $0 0 END #go to end
FileWrite $0 "echo off"
FileWriteByte $0 "13"
FileWriteByte $0 "10"
FileWrite $0 "start $\"$\" wusa $\"$strInstallPath$\""
FileClose $0
Execwait "$temp\RunMSU.bat"
