Thank you. I have produced two tables (DPC CPU Usage Summary Table and Interrupt CPU Usage Summary Tables), saved as Excel CSV files. But then I read that you mentioned: "now wait a time while the high DPC and Interreupt usage occurs." Do you mean I should wait until the next time my CPU starts working furiously, causing delays, to run the second command to produce the summary tables? I have already run the first one: xperf -on latency and hopefully this is running now! (Pardon me - as mentioned before, I have no knowledge on these kind of issues...).

Hi, I have been searching all over the place to find a layman's solution to stop this annoying system interrupt problem. Your solution seems the right approach and therefore I have (a) downloaded Web installer, selected Win32 Development Tools and installed them; (B) Ran wpt_x86.msi; © however, on running xperf –on latency, I got following error: "xperf: error: NT Kernel Logger: Access is denied. <0x5>". I don't know how to proceed. I admit, I am only a normal PC user without any specific expertise in hardware/ software/ programs and I would appreciate if you would please elaborate how to get over the obstacles. Thank you for your time and help. VDev
