-Query "SELECT * FROM Win32_Process WHERE Name='powershell.exe'" 还有一种比较晦涩,使用 wmisearcher 类进行query。 $query = [wmisearcher] "SELECT * FROM Win32_Process WHERE Name='powershell.exe'" $query.Get() 其中wmisearcher 是一类叫做 accelerator 的东西,除了 wmisearcher 之外,我们还有 wmi...
Well, X is equal to our counter data (PercentProcessorTime). Y is equal to 100NsTime, which means we'll use the propertyTimeStamp_Sys100NS. And although the time base is 100Ns. It's not used in the formula, so we'll just ignore it. Thus: ...
The SQL query asks for all instances (and all properties of those instances) to be selected and returned. The resulting set of objects that are returned are exactly equal using this form, but as will be clear in the examples to follow, the query form can be used to refine the number of...
