tokens=2* 即可

powerbat

skip不一定靠谱

for /f "tokens=2*" %i in ('reg query "HKCR\CLSID\{450D8FBA-AD25-11D0-98A8-0800361B1103}\DefaultIcon" /ve^|find "默认"') do set ICO=%j

另外你的系统是不是xp sp2？sp3之前的版本reg.exe命令有点小bug

powerbat

wmic /namespace:\\root\default path StdRegProv call GetExpandedStringValue "&H80000000","CLSID\\{450D8FBA-AD25-11D0-98A8-0800361B1103}\\DefaultIcon" | findstr sValue
复制代码

powerbat

for /f "tokens=2*" %a in ('wmic /namespace:\\root\default path StdRegProv call GetExpandedStringValue "&H80000000"^,"CLSID\\{450D8FBA-AD25-11D0-98A8-0800361B1103}\\DefaultIcon" ^| findstr sValue') do @for %x in (%b) do set ICO=%~fx

    没有xpsp2环境，xpsp3与win7都没问题。

powerbat

好像xp中wmi也有bug：如果一个键值从来没有被查询过，直接用wmi查询会失败。wmic返回ReturnValue=87，而vbs调用相应方法的返回值是2。
再次试验发现wmic和vbs都可能返回2或87。

楼主试试下面这样能不能得到结果

reg query "HKCR\CLSID\{450D8FBA-AD25-11D0-98A8-0800361B1103}" >nul
for /f "tokens=2*" %a in ('wmic /namespace:\\root\default path StdRegProv call GetExpandedStringValue "&H80000000"^,"CLSID\\{450D8FBA-AD25-11D0-98A8-0800361B1103}\\DefaultIcon" ^| findstr sValue') do @for %x in (%b) do set ICO=%~fx
