What games are you running? Are you running as an administrator on the
computer when you launch the games? This is only a problem if you're using
Windows XP Professional. A lot of games, especially children's games, were
written with Windows 98 / ME in mind so they don't handle NT's security
model very well.
Jimmy S. is one of Microsoft's MVP contributors. He has some great
suggestions for problems like these. I clipped some responses from one his
other posts to address the symptoms you're seeing here:
5. Your antivirus or application firewall might be conflicting with it.
- Disable the software temporarily.
6. There might be a patch available for your game to correct the issue.
- Try
www.avault.com/pcrl/patches_list.asp?letter=a/ or the game's site.
7. Your desktop may need to be set at least 800x600 and 16 colors.
- Click Start / (Settings) Control Panel / Click Display
8. Your Video, Sound, or Monitor drivers may need updating.
- Try updating your Video drivers using the instructions at:

9. You might have software running on your system which is causing
conflicts.
- Temporarily disable Startup programs one at a time, starting with
Firewall,
AV, and ad blockers using:
