mstsc.exe crashes on Windows 8 (and how to fix it)

Physical View of the Network

When using MSTSC (Microsoft Terminal Server Client aka RDP or Remote Desktop on Windows) to dial into a local HyperV virtual machine on my laptop it often happened that MSTSC crashed on me. When reconnecting afterwards, the VM was running just fine. So it seemed to be an issue on my local machine and not the VM. I assumed it had something to do with HyperV and RDP and didn’t look into it any further (I didn’t need it that much after all).

The exception code I got in my Event Viewer for the crash was 0xc0000005 on ntdll.dll.

But then I kept having this problem so often when connecting to a physical machine in the network it annoyed me enough to Google for a possible solution.
One post pointed me in the right direction (which I can’t find anymore, sorry about that), being that it had something to do with sharing of local resources. In my case I recently activated the option to transfer sound between the remote and my local machine so I could use Skype & Linq.

Turns out that was indeed the culprit. Whenever my remote machine made a sound, my RDP client crashed. Bummer!
Turning off sound transferring to my host machine made the crashes go away. Sweet!

So if you also run into this, try turning off some of those local resources.

It still sucks if you need sound of course, but in my case, I can live with the silence.

disabling Dell software without uninstalling

Yes, a cat. Cause it's the internet after all.

You know how it goes. You get this new and shiny computer from big computer company X and with it you don’t only get your OEM licensed Windows OS but also some “super handy” tools X happened to install just for you.

Dell is no different so mine come with Dell Data Vault, Dell SupportAssist and Dell Update Service. All of this is (of course) for your own benefit to update your machine to the latest drivers and blah blah blah, even though anything crucial is sent through Windows update anyway.

The downside is that these things are constantly running and using up your precious CPU and memory, while you’ll probably never need them. Ever. Oh, and they also come with some security vulnerabilities apparently, which is always a good reason to kick their butt.

I don’t know what Dell Data Vault even does and don’t care to either (its backup software probably). To make things worse it even causes my system to lag sometimes which I notice as my audio glitches up when that happens. I don’t always listen to breakcore you know, so I do noticed that sometimes.

I also noticed that uninstalling Dell Data Service is pointless as (I think) the Dell UpdateService will just reinstall it. Which sucks.

So I see two options.

  1. Uninstalling all Dell related software. This is kinda drastic and you might want that stuff if you need support after all.
  2. Disable the software and prevent it from starting up altogether.

So how do you stop those services from starting up automatically? Here’s how:

  1. On you desktop, press WindowsKey-R, this brings up the Run prompt.
  2. Type services.msc and hit enter. This brings up the list of services installed on your machine.
  3. Look for the Dell ones in the list.
  4. Open them, one by one, and in the General tab select the startup type “Disabled”.
  5. Hit “OK” to save.

How to disable a service from auto-starting.Note that in the screenshot I’m disabling a completely innocent service per demonstration as I don’t have a Dell machine handy with an English version of Windows on it.

From now on those pesky services won’t be wasting your resources anymore, until the day you might need them again. All you have to do then is go back into the services console and switch the startup type back to Automatic and save.
Then right-click the services in the list and choose “Start”, or simply reboot the machine.

But we’re not quite there yet. There’s still the case of PCDoctor and the SupportAssist client. Those sneaky startups are hidden in the scheduled tasks. You can disable them using the Task Scheduler like this:

  1. Press WinKey-R and type Taskschd.msc, press enter.
  2. In the list of scheduled tasks in the root node you’ll see a “Dell SupportAssistAgent AutoUpdate” or something similar.
  3. Right click the task and choose “Disable”.
  4. Repeat for any other Dell tasks in there.

They don’t all have “Dell” in their name, but if you check the Action tab below the path to the executable will give them away (like in the screenshot). In my case I had some additional PCD (PC Doctor) tasks and one SystemToolsDailyTest task to disable.

Another good tool to disable scheduled tasks if from the CCleaner tools menu, or by using the SysInternals Autoruns tool.The name of the task doesn't tell, but the path to the executable does indicate it's a piece of Dell software.

This worked for me, but as is mostly the case with things you find on the internet… use this info wisely and at your own risk. ;)

chocolatey package update quick reference


Chocolatey rocks when it comes to updating a bunch of installed software from the command line. If you’re not doing that often however it can be hard to remember exactly what commands you can use to do that quickly. So here’s a little run-down on the most helpful commands when you are updating your system.

First you might want to check what’s installed on your machine.
You can get the list of the local package Chocolatey installed like this:

chocolatey list -localonly

or in short:

clist -localonly

To check if any package have updates available, we can run the update all statement, but not quite for real yet. By adding the -whatif switch, Chocolatey only pretends to update:

chocolatey upgrade all -whatif


cup all -whatif

Ready to update all packages at once? Nice. So let’s disable those confirmation prompts while we’re at it too by adding the -y switch.

chocolatey upgrade all -y


cup all -y

Edited 2017-02-26 : replaced deprecated update command with the new Chocolatey 1.0 upgrade command.

disable javascript in firefox without plugins

This is one for the “it’s easy once you know” category.
In recent versions of Firefox the option to turn off JavaScript had apparently disappeared from the options. Recently I found out where those sneaky Mozilla devs have hidden this handy feature.

In the Firefox menu, go to Tools > Web Developer > Toggle Tools, or use the CTRL-I shortcut key to activate the developer tools side-panel. Once active you see one of those typical cog-wheel icons in the upper right corner showing the settings when you click it.
In those settings, scroll down to the Advanced Settings and flick the “Disable Javascript” check-box. Voila. JS is now disabled for your debugging purposes.

The “Disable Cache” option right above it is also a handy one if you are working on a page. It beats having to hit CTRL-F5 all the time anyway.

The disable JavaScript option in the developer tools settings.

If you want an easier way to control this, store settings per site and things like that, you’re better off installing the NoScript plugin. There’s a reason this option is hidden in the developer tools after all.

a vim http log file syntax plugin

Log files are dull to look at. Lines and lines of text and no pretty colors to make it nicer to look at and easier to spot those weird errors you can’t simulate on your machine.

Vim rocks and writing a syntax file is supposed to be a breeze judging from the vast amount of syntax plugins out there. I didn’t quite find one I liked for syntax highlighting HTTP log files, so I thought I’d get down and dirty with some vimscript myself and see if I could hack something together.

It turned out alright I think. So to share the fun I’m hosting the logsyntax.vim plugin on Github and the scripts library for all to use. It highlights dates, HTTP verbs, URLs, IP addresses etc for IIS, W3C extended, NCSA and probably a bunch more typical log formats.

May your logs be pretty and colorful from now on.

a wordpress full site spell checker tool

A while ago I noticed that some of my older posts had some silly misspellings in it, so I was looking for a way to spell check all my posts in one shot. I couldn’t really find anything that was free, so I figured I’d try to write something myself to do this for me.

I knew about the free and open source Hunspell spell checker and that you can use it from the command line. So I thought using that together with the WordPress export XML file which has all your post’s content it should be possible to spell check the whole lot.

The end result is a PowerShell script which reads out the XML export file and runs it through Hunspell, parses the spelling errors found and finally bundling it all into a simple HTML report.

It worked nicely for me, even though it’s pretty crude and simple. I only had to use this once, so I don’t see the point of fine-tuning it a lot further.

However this could be handy for others who want to do the same thing, so I cleaned it up a bit, slapped a readme file on it and posted it on Github as the WordPress full site spell checker.
Check it out if you want to spell check your WordPress blog in a single run and maybe this will be good enough to get your job done. You find more info on how to set up and use it on the Github page.

That very basic report I was talking about.

yo dawg I heard you like package managers

Let’s say you want to do this little web project, a SPA for example, and you want to settle for Angular as your JS framework. But downloading those scripts manually is so oldskool, so you need yourself a package manager to shoot those into your still empty project folder.

For example, with something like Bower, “the package manager or the web”:

bower install angular

Cool, so how do I get Bower?

npm install -g bower

Node Package Manager huh. Hmm. So I’ll need Node first. OK. I bet there’s a Chocolatey package for that.

choco install nodejs

Awesome! So how do I get Chocolatey (we’re clearly on Windows here, use your fav *nix distro package manager otherwise)?

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString(''))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Alright, now we’re talking!
What was I doing again?

As a Windows .NET dev you could also use Visual Studio Community 2013 of course, open up the Nuget Package Manager Console and run:

Install-Package angularjs

But how do you get Visual Studio (*)?
Oh, there’s Chocolatey again.

choco install visualstudiocommunity2013

Or maybe you can use WebPi…, or… argh. Never mind.

(Post inspiration by @mattiasgeniar)

(*) As a .NET developer you have this installed already of course, but to setup a new machine, Choco is the bomb.
