Excel 07 file open issues

January 6th, 2010 No comments

I ran across a problem recently whereby when a user would double click an excel file, Excel would open but wouldn’t display the file until Excel was minimized and maximized again.  The machine had a fresh installation of Windows XP on it, and had all of the updates available from Windows Update.  The files would open fine from the File > Open menu.

The solution came about from looking at the XLS and XLSX filetypes.  I noted one main difference on several machines that didn’t have the error compared to the one that did.  See below on how to fix it: Read more…

NTVDM error c0h

January 6th, 2010 No comments

Ran across an interesting problem the other day – a dos-based application would not start.  As soon as it was launched, an error c0h  in NTVDM was thrown.  The application was run from a share and was not an installed program.  Other machines were able to use the application without any problems.

Other 16 bit applications also had issues:  CMD would run fine, but COMMAND would not.  This led me in the direction of something patching the 16 bit subsystem of Windows XP.  I checked the AUTOEXEC.NT and CONFIG.NT files which were both as expected.  I then checked the system32 directory and found numerous malicious files.

Re-Enabling Windows Zip Folders

January 4th, 2010 No comments

Sometimes when you uninstall a program that handles Zip files you find that it doesn’t restore the original Windows zip folder functionality.  You can use the following in a command prompt to re-enable it!

regsvr32 %windir%\system32\zipfldr.dll

You  may need to restart windows for this to take effect.

Enabling NumLock at login

January 2nd, 2010 No comments

There have been far too many times when I’ve come to a Windows XP Workstation that doesn’t have numlock enabled at boot.

How to resolve?  A nice “Quick” fix is to update the registry.  Create a .reg file using the info below and import it in to the registry

Windows Registry Editor Version 5.00
[HKEY_USERS\.DEFAULT\Control Panel\Keyboard]
“InitialKeyboardIndicators”=”2″

Or just navigate to the relevant subkey in the registry and modify it.  If you look on: http://technet.microsoft.com/en-us/library/cc978657.aspx you can see that they specify it for the current user and it is supposed to get stored on a per-user basis.  The above just helps to set it as the default for the initial boot sequence.

A new year and a new start to the tidbits of information that I like to collate, discover, and reiterate to those who are interested.

Let’s see how well this all goes, shall we?
