Force VCExpress.exe to launch processes in lower priority

Question

0.00/5 (No votes)

I launch VCExpress.exe in BELOW_NORMAL priority. However, it calls bscmake.exe, cl.exe, link.exe, and possibly other processes in NORMAL priority. Is there a way to prevent this? One ugly and not very robust solution is to create a scheduled task that looks for those executables periodically and changes their priority? I've found one solution since posting: installation of Prio. This works for personal usage, but would require a license for commercial.

I am trying to modify my code that compiles from the command line, so that all related processes are in BELOW_NORMAL priority. That way, my computer does not lock up and allows me to at least surf the internet while I wait for compilation of multiple builds and more than a dozen projects to complete.

There are no options to do this. Everything is going to get launched at normal priority. Since you have no control over the code that is launching the compiler, you'd have to manually change the priority after it's been launched.

Installing Prio worked great. I am just not sure how they customized the task manager. Prio runs a service, so I am guessing that there is some type of event that is triggers when a new process is launched. Then prio's service automatically changes the priority to the one you saved.
