标题: [技术讨论] VBS个别lnk文件不能读取备注的研究 [打印本页]
作者: czjt1234 时间: 2024-3-27 10:07 标题: VBS个别lnk文件不能读取备注的研究
开始菜单中的 Windows Media Player 的快捷方式
win7 C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Windows Media Player.lnk
win10 C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows Media Player.lnk
win11 C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows Media Player Legacy.lnk
在使用 WScript.Shell 和 Shell.Application 对象读取其备注时
win7正常,但win10和win11会报错- '读取 Windows Media Player 快捷方式的备注,win10
- Set oWshShell = CreateObject("WScript.Shell")
- s = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows Media Player.lnk"
- Set oWshShortcut = oWshShell.CreateShortcut(s)
- MsgBox oWshShortcut.Description
复制代码
- '读取 Windows Media Player 快捷方式的备注,win10
- Set oShell = CreateObject("Shell.Application")
- s = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows Media Player.lnk"
- Set oShellLinkObject = oShell.NameSpace(17).ParseName(s).GetLink
- MsgBox oShellLinkObject.Description
复制代码
打开该lnk文件的属性,可以看到win10和win11环境下,备注为空
但是一个备注为空的lnk文件,读取备注应该是空字符串""
根据微软的lnk文件的二进制说明
https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-shllink/16cb4ca1-9339-4d0c-a68d-bf1d6cc0f943
读取 Windows Media Playerr.lnk 快捷方式的备注
结果为 @%systemroot%\syswow64\unregmp2.exe,-155
测试,把其它快捷方式的备注改为 @%systemroot%\syswow64\unregmp2.exe,-155
结果也是属性无法显示备注,vbs无法读取备注
测试,把快捷方式的备注改为 @%systemroot%\system32\unregmp2.exe,-155
结果是属性可以正常显示备注,vbs可以正常读取备注
备份 syswow64\unregmp2.exe 和 system32\unregmp2.exe 文件
再把这两个文件互换,结果还是
@%systemroot%\system32\unregmp2.exe,-155 正常
@%systemroot%\syswow64\unregmp2.exe,-155 报错
说明与文件无关,而是win10和win11锁定了syswow64
锁定快捷方式的备注不能读取syswow64里的文件
测试,用syswow64\WScript.exe在32环境下运行上述的2个vbs
结果均能正常显示
此时再查看属性,发现可以正常显示备注
包括备份到其它盘的 Windows Media Player.lnk 也能正常显示
说明此时已经解锁了syswow64
快捷方式的备注可以读取syswow64里的文件了
再用二进制读取解锁后的 Windows Media Player.lnk
结果没变 @%systemroot%\syswow64\unregmp2.exe,-155
win10和win11虚拟机恢复镜像后,可以复现上述操作
猜测,这是win10和win11的一个bug
毕竟微软和波音一样,裁减了99%的测试员

那要是改了syswow64里文件的lnk的目标文件 description还会读去不了吗^_^
