ghost updates

Ghost updates are updates that repeatedly fail to install or remain stuck in the Windows Update queue, often showing error codes like 0x80070490 or 0x80070103. In Windows 10, users have encountered ghost updates for HP Photosmart 7520 series drivers, where the updates appear as 'Null Fax' or 'Null Print' entries and refuse to install. Troubleshooting methods include removing problematic registry keys, though Microsoft has removed some older workarounds. These updates can clutter the update list and prevent other updates from installing properly. The tag covers user experiences and solutions for identifying and removing ghost updates on Windows systems.
