Windows 10: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment =>...

I am looking for a way to safely change my instrument name within my session manager environment. Below is the pathway in windows registry:Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment => InstrName ;Can I just edit this name via the windows registry?

:)

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows - csrss.exe MaxRequestThreads= range?

Greetings:

I had been trying to search for documentation on this but does anyone know for the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows registry key which involves csrss.exe, what is the range or limit for the MaxRequestThreads= variable?

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows - csrss.exe MaxRequestThreads= range?

Many thanks, on my system being a notebook running 500 processes, it seems here is what happens:

If I have the MaxRequestThreads=x

where x is the default of 16, the CPU will have a utilization of under 50% for a few hours then stuck at 99% where the system will remain sluggish until rebooting

when I increase this to 128, the CPU will have a utilization of under 50% for a day and then stuck at 99% the next day where the system will remain sluggish until rebooting

I am currently trying 256 and so far, after 11 hours of uptime, the CPU usage is at 25%.

So I am trying to figure out what is the maximum number one can use safely without triggering a BSOD as I am not sure if I can fix the BSOD if it is caused by a setting in the registry should it happen since I will no longer be able to boot the system if that happens. I had never tried 32 but it seem that number would not work well from my tests as mentioned above.

I also have the following resource hacks:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows

Windows SharedSection=1024,20480,8192

from

Default Value: 1024,20480,768

For GDI handles change the following Registry Keys:



HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota



HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota



Change it to 65536

Range: 256 - 65,536. Default value: 10000



For USER handles change the following Registry Keys:



HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota



HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota



Change it to 18000

Range: 200 - 18,000. Default value: 10000

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows - csrss.exe MaxRequestThreads= range?

I was wondering if someone could help me with resetting the Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent

settings. There has been a change made and now I get an error that "Can't connect to this network" each time I try to connect to a wireless network. I have never had issues before the settings were changed in regedit.
