I'm writing my own task manager as I often change process priorities but have gotten myself into trouble on several occasions. I have discovered by keeping csrss.exe and explorer at the equal highest priority, I can keep the computer running ok, or at least recover. So that's what my program does - keeps itself and those programs with high enough priority. It works great when run from visual studio, but as soon as i run it directly (whether in release or debug mode) I cannot access the process priority of csrss.exe. Is this a security issue
The error message begins like this
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box

Hi,
When I start a console program using the Process calss inside the
Visual Studio IDE (debug) all the output is redirected to my stream
reader. But when I run the same program from outside the IDE the
process opens a new shell window for the program and my program is put
on hold.
How can something work inside the IDE but not outside?!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
