卸载程序的重要注册表项是什么？

Question

一个简单安装程序的NSIS示例提供了一堆要写入注册表的条目。真的所有这些都是必要的吗？什么是“最低限度”？

# Registry information for add/remove programs
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "DisplayName" "${COMPANYNAME} - ${APPNAME} - ${DESCRIPTION}"
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "UninstallString" "$\"$INSTDIR\uninstall.exe$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "QuietUninstallString" "$\"$INSTDIR\uninstall.exe$\" /S"
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "InstallLocation" "$\"$INSTDIR$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "DisplayIcon" "$\"$INSTDIR\logo.ico$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "Publisher" "$\"${COMPANYNAME}$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "HelpLink" "$\"${HELPURL}$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "URLUpdateInfo" "$\"${UPDATEURL}$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "URLInfoAbout" "$\"${ABOUTURL}$\""
WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "DisplayVersion" "$\"${VERSIONMAJOR}.${VERSIONMINOR}.${VERSIONBUILD}$\""
WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "VersionMajor" ${VERSIONMAJOR}
WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "VersionMinor" ${VERSIONMINOR}
# There is no option for modifying or repairing the install
WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "NoModify" 1
WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "NoRepair" 1
# Set the INSTALLSIZE constant (!defined at the top of this script) so Add/Remove Programs can accurately report the size
WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\${COMPANYNAME} ${APPNAME}" "EstimatedSize" ${INSTALLSIZE}

来自uninstaller

顺便说一句:谷歌搜索只给出了如何在卸载程序后清理注册表的提示，当被问到这个关键字时。

Answer 1

DisplayName和UninstallString是必需的。

其他所有内容都是可选的，但是会给出一些警告，如果其他条目丢失了。

可选条目显示在Windows 2000及更高版本的UI中。
