Hello, Stephan55. Thank you very much for sharing your issue with the Intel Communities Team. I will be more than glad to assist you.
Let us try this:
1. Start Control Panel, click Hardware and Sound, and then click Device Manager.
2. Expand "Display Adapter", right-click the Intel Graphics entry, and click Uninstall.
3. On Confirm Device Removal dialog box, click Delete the driver software for this device option to delete the Intel HD Graphics driver then click OK to start the uninstall process. Repeat this process until you are able to see the Microsoft Basic Display Adapter on the "Display Adapter" entry.
Once these steps are performed, please install the latest Intel® HD Graphics drivers for your system. Click https://downloadmirror.intel.com/22520/a08/Win7Vista_64_152258.zip here to download the drivers and follow this guide to complete the installation: https://www.intel.com/content/www/us/en/support/articles/000005474.html https://www.intel.com/content/www/us/en/support/articles/000005474.html
Please be aware that the driver I am sharing with you is a generic driver from Intel® and some features of it might not be available for your machine, we always recommend verifying if there is any update with the manufacturer of the computer. Nevertheless, we can try to perform this troubleshooting step.
