问题 To get the drive the current batch resides in is easy using set batchdrive=%~d0 But how is it possible to check if %batchdrive% is on a local drive and not on a (mapped) network share? Checking for %SYSTEMDRIVE% or a fixed list "C:" "D:" ... is not reliable. 回答1: To check whether a drive ( %~d0 ) is a local one, you could use a wmic query: wmic LogicalDisk where(DeviceID="%~d0" AND DriveType=3) get Description,DeviceID,DriveType Given that %~d0 expands to the local drive C: , the output looks

问题 I'm trying to create a cmd file that will install a .msi and then execute that cmd file via C# code. The code works perfectly if I run it using f5 or control + f5 from visual studio. However, once I package up the code in a .msi file and install it (it's a wpf app), when it executes the relevant code, it opens the command window but it doesn't execute the command. Instead it says: "C:\Program is not recognized as an internal or external command..." I know this error means that there aren't

问题 as the title says I search for a way to enable/disable the Hotspot inbuild in Win10 via the command prompt/powershell/a batch file. In the GUI it can be easily done with the third button in the network panel (see image below), but I want to automate it.

Or does Win10 the same and everytime creates a
