CompatTelRunner.exe and 100% SSD utilization

Posted by essjae on August 7, 2017

This happened to me on Friday.  My system slowed way down and got very laggy.  Check Task Manager and Resource Monitor.  My C: SSD was at 100% utilization.

The culprit, compatTelRunner.exe.  This is apparently something that was used for Win7 compatibility checking for Win10.

I’ve got Win10 and this wasn’t an upgrade.

Anyway, you can disable this via task scheduler.

  1. Click Start, then type task scheduler and press Enter.
  2. On the Task Scheduler window, go to Task Scheduler Library\Microsoft\Windows\Application Experience
  3. In Application Experience, find Microsoft Compatibility Appraiser.
  4. Right-click Microsoft Compatibility Appraiser and select Disable.
  5. Kill any comptelrunner.exe tasks running and your system should become usable again.
    1. Alternatively, just restart your computer

Dell Broadcom USH Drivers

Posted by essjae on July 13, 2017

This always happens to be when I do a fresh install of Windows on a Dell notebook…

Dell’s got a page now with drivers for most of their recent computers:

Download herehttps://www.dell.com/support/article/us/en/19/sln129590/download-the-broadcom-ush-drivers-and-resolve-unknown-device-issues?lang=en

These are the ones I use the most.  Windows 10 x64 drivers for the Latitude e6540, e7240, e7440, and Precision M4800, Latitude e7270

Windows middle-button scroll icon!

Posted by essjae on April 21, 2017

I was trying to find an icon for this to put in a document, but couldn’t find one with the circle and all 4 arrows, so I made my own.

In case anyone else needs one, here you go.

It’s not perfect, but good enough for internal tech docs.

VMGuest.iso for older Windows OSes in Win10/2016

Posted by essjae on March 2, 2017

If you’re playing around with older OSes in the latest versions of Hyper-V, you’re missing one thing, the Integration Components (IC).

With Win10/Server2016 they no longer include this ISO as the current “supported” OSes all get their IC viaWindows Update.

You can get the IC from Hyper-V 2012/2012R2 Server, a free download, here:

https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2012-r2 (you’ll need to either find a way to extract it or install Hyper-V Server in a VM to get the vmguest.iso)

Or, if you’ve got a Windows 8/8.1/2012/2012R2 VM/system available with Hyper-V installed you’ll find it in the C:\windows\system32\ folder.

I’ve got a copy from Hyper-V 2012 R2 here: https://1drv.ms/u/s!AnbqFQxI6C6pidtRrLfIRLDSHKeYmw

No guarantees how long MS will allow it will stay up here, though it’s freely distributed with Hyper-V Server.

No More Ransom Compiles List of Free Anti-ransomware Tools

Posted by essjae on December 16, 2016

“The No More Ransom project, a coalition of law enforcement and security companies, has expanded with 30 new members and added 32 new decryption tools for various ransomware variants,” Computerworld reports.

First launched earlier this year, the No More Ransom project is headed by Europol’s European Cybercrime Centre, the National Tech Crime Unit of the Netherlands’ police force, Kaspersky Labs, and Intel Security. As of today, No More Ransom has announced that Bitdefender, Check Point, Emsisoft, and Trend Micro have joined as associate members. “Other companies, computer emergency response teams, information sharing and analysis centers, and industry associations have joined the project as supporting partners,” Computerworld says. “The organizations have contributed an additional 32 new decryption tools to the existing eight, which have so far been used by over 6,000 victims to successfully recover their ransomware-encrypted files.”

Easy (lazy) way to get your serial number for your Dell, or other OEM system?

Posted by essjae on November 15, 2016

Need your serial number?  Laptop’s docked, or workstation not easily accessible?

Here’s an easy way to get your vendor serial number:

  1. Start a command prompt, click start, type “cmd”, hit enter
  2. type “wmic bios get serialnumber”

This will return your Dell, Lenovo, etc serial number.

Note: If you have a custom or home built system, you’re not likely to get an serial number, you’ll probably see something like  “system serial number” or “to be filled in by o.e.m”
