The csrss.exe file is not really what i'd call 'dangerous', however if the process is ended, it will cause a crash. Houdina: if you have 2 of them, one is fake, delete one that is not 'system' lol: csrss.exe (Server Client Runtime SubSystem) is an important file in the windows operating system. Stress.exe is a harmful downloader Trojan that can download addition pc threats to the compromised computer. For example, popular rogue software like are usually install on a target computer with the help of downloader Trojan. Stress.exe is just as dangerous as backdoor Trojan.

Testlimit is a command-line utility that can be used to stress-testyour PC and/or applications by simulating low resource conditions formemory, handles, processes, threads and other system objects.

usage: Testlimit[[-h [-u]] [-p [-n]] [-t [-n [KB]]] [-u [-i]] [-g [object size]] [-a -d -l -m -r -s -v [MB]] [-w]] [-c [count]] [-e [seconds]]

-aLeak Address Windowing Extensions (AWE) memory in specified MBs (default is 1)
-cCount of number of objects to allocate (default is as many as possible). This must be the last option specified
-dLeak and touch memory in specified MBs (default is 1)
-eSeconds elapsed between allocations (default is 0)
-gCreate GDI handles of specified size (default 1 byte). Specify a size of 0 to cause GDI object exhaustion
-hCreate handles. Specify -u to also allocate file objects
-iExhaust USER desktop heap
-lAllocate the specified amount of large pages (rounded to large size multiple)
-mLeak memory in specified MBs (default is 1)
-pCreate processes - add -n to set min working set. Add -n to set min working set of processes to smallest
-rReserve memory in specified MBs (default is 1)
-sLeak shared memory in specified MBs (default is 1)
-tCreate threads - add -n to specify minimum stack reserve (in KB)
-uCreate USER handles to menus
-vVirtualLock memory in specified MBs (default is 1)
-wReset working set minimum to highest possible value

This automated test verifies system stability while running many GPU-bound memory intensive applications when all patch locations are always repatched via the Patch DDI. Rugby 08 on mac.

This test creates many processes that do D3D9 rendering with a large video memory working set. This causes preemption and paging to occur on the GPU. The test puts the operating system into a mode that causes it to repatch all patch locations via the Patch DDI. Display drivers must not cause the system to crash or stop responding (hang) while running this test.
