## Windows Live Messenger Uninstaller v0.01

This is the first public version of the Windows Live Messenger Uninstaller (v0.01).

What the tool does is basically remove a broken Windows Live Messenger installation. It really uses only the windows installer (msiexec.exe) to do the job combined with the CLSID of the installation that uniquely identifies the WLM version.
The symptoms might be that when you want to reinstall the application it might say that it is already installed, while actually it is not. When trying to remove it with the usual Configuration – Add/Remove software steps, it might not even appear in the list, while the setup of the WLM says it is really installed.

I decided to build this tool since there are a lot of people strugling with this problem [1][2][3][4]. All these existing solutions presented by people on these sites use the single command with a CLSID key (eg. msiexec /x {B1403D7D-C725-4858-AACC-7E5FA2D72859}), but since the key is different for each WLM version such a solution might only be useful if you have that exact version. It can also be done manually by changing the registry keys, but I thought this would speed up the work significantly since there might be a lot of keys to search in (The location we are talking about here is: [HKEY_CLASSES_ROOT\Installer\Products\])

I heard of people formatting the entire hard drive because of not being able to resolve this, so I really hope this gets around and avoids a lot of headaches.

Requirements
The tool is tested on Windows 7, Vista and XP.

Usage
The tool is very simple to use. If it finds an installation it will give you the uninstall command that you can use to manually remove it. You can also press RUN and it will run the command automatically for you.

Future releases
If you have any comments, suggestions or bugs, please put them here in the comments. If it is useful I might add/fix it in the next release.

Currently I’m planning to build a more general remover for the Windows Live series, since there are also other components that could get broken.

The link to this topic is already published on several sites, but unfortunately the presented description of the tool is misleading. For it says that I’m claiming to have a better tool than all the other existing solutions, which is of course not true. This is only another alternative that may solve the problem.
In my description I was only referring to the existing solutions presented on the topics and comments on these that I used as references (see above [1][2][3][4]) and not on any other existing tool that probably uses other methods.

Windows Live Essentials Uninstaller
If you also want to remove other Windows Live Essentials components like Windows Live Mail or Windows Live Movie Maker, then try a similar tool that I have built called Windows Live Essentials Uninstaller. This tool can remove any component installed by Windows Live Essentials.

## LaTeX MSC package error

While using the MSC (Message Sequence Chart) package (msc.sty) I couldn’t compile my document by using PDF Texify in WinEdt. With the following sample code

\documentclass{article}
\usepackage{msc}
\begin{document}

\begin{msc}{Example}

\declinst{usr}{User}{}
\declinst{m1}{Machine 1}{control}
\declinst{m2}{Machine 2}{drill}
\declinst{m3}{Machine 3}{test}

\mess{startm1}{usr}{m1}
\nextlevel
\mess{startm2}{m1}{m2}
\nextlevel
\mess{continue}{m2}{m3}
\mess{log}{m1}{envleft}
\nextlevel
\mess{output}{m3}{usr}[2]
\nextlevel
\mess{free}{m1}{usr}
\nextlevel

\end{msc}

\end{document}


I get this error

! Undefined control sequence.
..
\declinst

I don’t know why exactly this happens, but the error suggests that it probably calls a command that doesn’t exist. Anyway, a quick fix (in WinEdt – MikTeX) is to do the following:

1. LaTeX compile it (Shift+Ctrl+L).
2. Then convert the .dvi file to .ps with DVIPS.
3. Finally use PS2PDF to get the PDF.

Any other sugestions are welcome.

## Realtek High Definition Audio not recognized on Windows 7

Overall, old drivers like Windows XP drivers are well supported on Windows 7. But as usual, not everything goes always as planned.

In this case I had to fix a not working sound card. To be more specific, it was a Realtek High Definition Audio onboard sound card. The card was just not recognized by Windows 7, while it did when I was running XP on that same machine. And this was was very strange.

My situation was fixed with a really simple fix. You might try the following:

1. Start your computer and enter your BIOS by directly pressing F1 (or F10 or any other key depending on your machine)

2. Go to the advanced menu or somewhere where you can see Onboard Audio.

3. You might now have 3 options to choose. Disabled, Enabled and Automatic.

4. If it is set on Automatic then change it to Enabled and start Windows as usual.

5. If you’re lucky Windows might now recognize the driver and even directly install it. 🙂

If it the above doesn’t work for you:

• Try my alternative solution here.
• You can try installing the driver by downloading the Realtek HD Audio driver for Windows 7 from the official site.
• In some cases you might also necesseraly need to install the chipset drivers for your motherboard.
• You can also try deleting the current audio drivers and reinstalling them.

## Windows 7 Update Settings Disabled

Strange things happen. So is it in this story, in the world of the new Windows 7 (which is quite an improvement after Vista but we all know that).

So on a nice shiny day, a nice update comes in and the part that bothers me the most is when it does automatically installing without my approval. Then just change the settings, I thought. But you might be as suprised as I was when I saw that this option was simply greyed out, which was of course even more bothering.

Anyway, the solution is quite simple as was in one of my previous posts with getting rid of that Officepluginres error message. You just fire up your registry editor and go to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Then you’ll find a key named AUOptions. You can change these values to 1..5 which represent the following options (the first four do grey out the option box in my case):

5: Enable the option box to choose manually

When you change it to 5, it will enable the option box and let you choose manually. There might be some other tweaks on this by changing the Group Policy, but this quick fix should also do the work.

## How to remove rootkit/spyware Virtumonde

You can read a lot about antivirus and antispyware software failing to catch up with the explosive growth of viruses that are surrounding the net. For the first time, I saw all the software really failing to remove a virus, even if it knew that it was there.

My first encountering of the spyware was a few weeks ago (on a machine not of my own). I lost an entire day searching for a remedy, that resulted in nothing. My first try was to just do a basic scan with the available software (NOD32 and SpyBot), which detected the virus, but couldn’t do anything to remove it. Trying in safemode, was the obvious next step. I was surprised to see that virtumonde even loaded in safemode, and therefore I couldn’t remove it. Then I began my search on the net with the hope to find some quick solution (time is precious). Hours after trying to remove it from starting, various virtumonde “fixes”, other antivirus and spyware software, it ended in nothing.
I was really determined not to surrender to this nasty peace of software, and therefore I had one last hope: isolate XP, and remove the damn thing manually. So I booted with Hiren’s Boot CD a mini version of XP, with which I hoped to remove virtumonde while it wasn’t active. I did in advance locate the files and registry keys (which I got by scanning with Spybot). And finally, when I deleted the files, removed the registry keys, booted up the machine, the virus was eliminated! 😀

To sum things up, the spyware is nasty, really nasty. Haven’t seen any other spyware that was more persistent than this. If you get infected by something like this, you end up either formatting your drive or do it manually like I did. There may be other, maybe easier ways, to overcome this problem, but here’s one solution that worked for me:
1. Scan the system with SpyBot and locate the files that it found
2. Delete them with SpyBot and reboot the system
3. Boot mini XP with Hiren’s boot CD
4. Now go to the windows system folder (or there where the files were reported), and sort the files by modification date. Because we deleted the files in step 2, the virus should have recreated itself again. So this is a quick way to identify all the files, since these are the last created ones.
5. Remove these files and any other files that were reported in step 1
6. Reboot the system and do a final scan with spybot, to make sure it is completely removed
7. You should be very happy now. 😀

There are some “addins” that are used by all office programs, and apparently the contribute plugin somehow got broken on my system.

The error while starting any of the office programs might look something like this:
“Unable to load OfficePluginRes.dll. Contribute may not be installed properly.”
