AccessChk.exe v5.11 doesn't seem to work with UNC files. The older v4.23 does work.  So it appears to be a bug.

AccessChk.exe v5.11 doesn't seem to work with UNC files. The older v4.23 does work.  So it appears to be a bug, v5.11 always says "No matching objects found".

Subject: Generate a Log file on marked PID
Posted: 02 April 2014 at 10:17pm

Request to have the ability to tag / mark an active PID in the Process Explorer list and have the details logged into a file until the PID is "unmarked" or de-selected. Additionally, have the ability to import that log file into Excel in order to generate activity and percentages into graphs or charts. Specifically, looking to understand per application (tagged PID) resource utilization over a time frame of usage (1+ hours). For example, complex application consuming CPU (cores), internal memory, GPU cores, GPU memory, network bandwitdh, etc. to determine bottleneck on performance and identify area to correct.

Hi, I know this is an older post, but hopefully someone can help me, I'm searching for what is causing latency because I just bought this laptop, and I'm already having latency issues.  I've followed the steps and believe I've gotten the correct page, but don't know how to read the text to find the problem. I'm totally noob, so it looks like gibberish. any help is appreciated thanks.  :)

the high CPU usage comes from ntoskrnl.exe!RtlScrubMemory. I've asked MS some time about it and this does a RAM check. So this is by design. The more RAM you have the longer it takes.

I went to my network adapter section under device manager, and clicked update driver software, under each thing there, and got nothing it said the best driver is already installed. I have no idea what and etl file is.

go to the website of the manufacture of the network card and download the latest driver.

The ETL fiel is the file which was created by xperf.

o.k. so I have gone to the toshiba website and downloaded everything there, that was a new driver, because under my network tab there are like 5 things, there and you said to just update it, and I don't know which one is which. nothing is fixed at all. this problem is so complicated to me, and I have no clue what I'm doing. please, please be more informative with your answers. I am not a person that knows what they are doing really, and it take so long to google everything you say just to end up still not knowing what to do.  I have taken screen shots to try and show you what it looks like but this forum won't let me upload them for some reason.

Thanks for the help, I never realized that I could load symbols in WPA (although I should've realized, it makes sense!) I only had them enabled in process explorer.

Subject: Sudden High CPU Usage
Posted: 05 April 2014 at 3:13am

My computer never used to do this, but recently, it has been suddenly spiking to 98%-100% for no apparent reason. I got Process Explorer to have a further look into it and it told me that there are 2 files using a large amount of CPU. These files are: System Idle Process, which i have read that it is supposed to have high Usage, and then there is this file, which does not come up in Windows Task Manager called "Interrupts". These are the details on this program:
CPU - 20% (Average)
Private Bytes - 0
Working Set - 0
PID - n/a
Description - Hardware Interrupts and DPCs
Company Name - *Nothing here*

I have read online in many different situations that people are having similar problems. I just wanted to clear up that i do NOT have a CD/DVD Driver. the problem is not Malware, i have run a scan multiple times. And the problem is not my Registry, i used CCleaner to repair that. Although, when i ran the Malwarebytes Anti-malware, it told me that i had a trojan and many different areas of my computer had been hijacked. These problems have since been resolved.

The Stats for my Computer are:
MS Windows 7 Enterprise 32-bit SP1
Intel Core i3
CPU U 380 @ 1.33GHz
4.0GB RAM
Intel HD Graphics

If anyone could help, that would be greatly appreciated

# can't debug irp hang because kd won't display irp stacks

russinovich do you want to fix kd so that it display the irp stack when it's larger than 30?, because

* i can't debug this https://github.com/mirror/windows/issues/1 \FileSystem\Ntfs bug because it often occurs when kd just tells me "Too many Irp stacks to be believed (>30)!!" i.o.w. kd tells me "go f. yourself" rather than "let me tell you were the bug is"

* you have access to the kd source, i don't, i can't create a PR for it in GitHub because you haven't open sourced kd like you should do to let us fix ridiculous bugs like this

Posted: 05 April 2014 at 10:27am

There is a bug with Process Monitor 3.1.  When You click Help > Help, you get the "Unable to open help file" error.  To enlarge any of my JPG's in Flickr, click on the JPG, then click on the largest box on the upper right.  To enlarge it further, click on "Original" on the next screen.

To fix this problem, I started Process Monitor 3.1 and captured the events related to Procmon64.exe when I clicked Help>Help.  I have screen captured and highlighted the correct line.  Procmon64.exe is looking for a Registry Key and not finding it.

You must edit your Registry.  Go to this key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\HTML Help]
and add this expandable string value: procmon.chm with the value:
C:\Program Files (x86)\Sysinternals\Process Monitor

In order for the above value to work, you must install Process Monitor into the above folder.  If you wish, you may download, extract, and double-click the procmon-chm.reg file in this procmon-chm.zip file.  Use the REG and ZIP file at your own risk.

Be aware, in addition to the above problem, I also had to right-click on the procmon.chm file, select Properties and click on the Unblock button in the General tab.
