The Default Num Lock Status

numlockDefault Num Lock is on or off controlled in the bios of a computer. In enterprise environments there is usually a bios password. So users aren’t allowed to change the default behavior of Num Lock (on or off).

Windows has a built in trick for this.

When the computer boots and the login screen is displayed set Num Lock to the preferred status. Then DON’T login but restart/shutdown the computer. The next time Num Lock is just the way the users want’s it Knipogende emoticon


Q: Is is possible to let users change the default Num Lock status with a BIOS password?

A: Yes, set the preferred status at the login screen and reboot the pc.

There is even a solution for doing this in the registry.

  1. Start the registry-editor.
  2. Go to HKEY_USERS\.Default\Control Panel\Keyboard.
  3. Change the value of InitialKeyboardIndicators from 0 to 2.

TrueCrypt and reinstalling Windows

I’m using TrueCrypt for a while now, and like any other nerd Knipogende emoticon I’m reinstalling my pc on a regular basis. And there comes the problem. Because TrueCrypt has encrypted the whole disk, I have to enter the password when the computer boots from HDD. When booting from DVD de HDD is still encrypted and the only way to install Windows is to wipe the HDD (repartition and format). I have a second partition (D Drive) with my data. So when reinstalling Windows I only have to format the first partition (C Drive). You get the problem??? Knipogende emoticon The solution is to encrypt only the second partition (D Drive). But the problem then is that my important documents are back upped to the cloud (a DropBox construction) and the agent, responsible for that, is started at boot. When I’m to late entering the password for TrueCrypt password the agent gives an error. But reinstalling Windows is easy Knipogende emoticon Anyone else who have the same problems? Comments are welcome… Update: Oke, time to do some research/”trial on error” about reinstalling Windows… I have 1 partition with Windows installed, and 1 partition with aprox 40GB data. Both on the same harddisk. The data partition is encrypted with TrueCrypt. I have the recovery disc. When booted from the Windows 7 installation DVD, I can see both the partitions but the encrypted partition is empty (100% free disk space). I choose the Windows partition, format and install…. wait….. After installing the first thing I did was installing TrueCrypt. Then mounted the data partition and all the data was not accessible. I rebooted the computer with the recovery disc, choose F8 (repair options) and then 1 (Permanently decrypt system partition/drive). Type the password and…. “Incorrect Password” WTF…. Oke, option 3 (Restore key data). Modify drive 0? YES Please Knipogende emoticon…. Header restored…Rebooting Windows… Data still not accessible. Damn this is getting frustrating… Rebooting again with the recovery disc. Choose F8 and the option 1. Type in the password… There is a warning that this is much faster in Windows. But I’m not able te decrypt the data partition only in Windows Bedroefde emoticon So I select YES. My laptop is doing around 7MB/s and the HardDisk is 150GB…So it’s time to eat, watch The A-Team etc.. The next morning the decryption was ready. All the data is now available. Not an option for me. Reinstalling takes a verry long time so. Conclusion.. Before you reinstall Windows on a TrueCrypt protected partition/disk, first copy the data to an USB disk. Then install Windows, Encrypt the partitions en copy back the data.

SCCM Remote Control for Servicedesk

Within SCCM there is a functionality to remote control desktops. Because all the desktops and laptops have a SCCM client installed, it’s the logical way to use this feature. So no extra third party software must be installed/deployed.

On the site server the are two files named: rc.exe and rdpencom.dll Copy these two file to the servicedesk desktops so they can access them. (for Windows 2000 clients use remote.exe)


Open the SCCM Management Console and navigate to: Client Agents. Right click on: Remote Tools Client Agent select: Properties.


Add the Servicedesk User Group in the security tab.


And your done. When the rc.exe is started. Click: File –> Connect. Give the computer name to remote control, wait for acceptance and happy shadowing. Knipogende emoticon

Q: Howto arrange remote control for the servidesk with the SCCM tools?

A: Copy rc.exe and rdpencom.dll from Site server to servicedesk, give servicedesk group rights to permit remote control.

Choose to install specific software during OSD Task Sequence

During an OSD task sequence, I want the option to select if certain software is installed. This can be done by third party software solutions (like OSD++) but with ‘variables’ it’s possible direct in SCCM.

In this example I’m using the Windows XP Task Sequence which is advertised to the All Unknown Computers Collection and I want to choose to install AutoCAD 2010.


Right click on the collection and choose: Modify Collection Settings.



Go to tab: Collection Variables click on the new variable icon. Give the variable a name like: Install_AutoCAD_2010 and leave the value empty.



Edit the Task Sequence and go to the step where AutoCAD 2010 is being installed. Open tab: Options. Add a condition like the screenshot below.


When running the Task Sequence you are presented a screen where you set the variable. Set it to 1 to install AutoCAD.

Q: Howto filter software during OSD Task Sequence?

A: Create a variable to the collection and add it as a condition in the Task Sequence.
