Cbucolo,
The "msmsgs.exe" is the main executable for Windows Messenger and also helps with MSN Messenger. If you don't use MSN Messenger, then it should be easy to disable that program from running at start up. Follow the instructions below:
In order to stop the Windows Messenger program from loading at start up, but still allow it to be available when needed:
1. Open Windows Messenger by clicking on Start-Run, type 'msmsgs.exe' (without the quotes), click OK, or click Start-Programs-Windows Messenger.
2. Click on 'Tools' in the upper left, choose 'Options'.
3. Click on the 'Preferences' tab, then UNCHECK the box next to 'Run this program when Windows starts'.
4. UNCHECK the box next to 'Allow this program to run in the background'.
5. Click on 'OK'.
In order to stop it from running when opening Outlook Express:
1. Open Outlook Express.
2. Click on 'Tools' in the upper left, choose 'Options'.
3. On the 'General' tab, UNCHECK the box next to 'Automatically log on to MSN Messenger Service'.
In order to stop it from running in Microsoft Outlook:
1. Open Outlook
2. Click on 'Tools' in the upper left, choose 'Options'.
3. When that loads, click on the 'Other' tab, then UNCHECK the box next to 'Enable Instant Messaging in Microsoft Outlook'. Click on 'OK'.
Hope this helps.
