Steps to change priority of wireless networks in Windows 10. Open the elevated command prompt (Admin) and type the following command: netsh wlan show profiles This command result will display all the connections that are linked to your computer. So you see the connections appear in order of precedence. If you want to change the order of precedence, enter the following command.

For more options, I suggest you to refer the man pages of nice and renice utilities. $ man nice $ man renice.

As you can see from these snapshots, only 6 priority types (as it will be explained later, these are the priority classes) are available. Is it enough? Microsoft thinks, it is.
But let’s remember the epic saying by Bill Gates, who told that “640 KB of RAM will be enough for everybody”. Normal: the same as the process has. Above normal: +1 to the priority of the process. Below normal: -1 from the priority of the process.
Highest: +2;. Lowest: -2;. Time critical: sets the current priority of a thread as 31 for the Real time class, and 15 for the rest classes. Idle: sets the current priority of a thread as 16 for the Real time class, and 1 for the rest classesThe following table shows process priorities, relative and current priorities of a thread.

Start a task/process and change its priority using Task ManagerMethod disadvantages:. Only 6 types of priorities are available. The priorities are changes with your mouse and you cannot make it automatic.Method 2. I won’t give the example of running this command as the list of processes is too long.
Do it yourself if you want to.You’ll get the list of processes run on your local computer. Now run this command:wmic process list brief find 'cmd.exe'Here is the result:I have deliberately started several copies of cmd.exe, to make it more demonstrative.Now the list of processes is limited to those having “cmd.exe” in their name. Pay attention to the PID of the process(es).Now let’s try to select the necessary processes using WMI.
To do it, just enter:wmic process where description='cmd.exe' list briefHere is the result:Compare the results. Remember the PID of CMD.EXE.The command string to start wmic.exewmic process where processid='XXXX' CALL setpriority ProcessIDLevelNow we can change the priority of a specific process (e. G., PID=8476):wmic process where processid='8476' CALL setpriority 32768orwmic process where processid='8476' CALL setpriority 'above normal'What next? Think, try, select and manage your priorities to improve the performance of services and processes, together with the end user experience.
