Hallo EnricoK1,
Generally, upgrading to Parallels Desktop 26 should maintain compatibility with your existing Windows XP virtual machine. However, before performing the macOS Tahoe update, it is highly recommended to:
- Back up your VM file: Locate your .pvm file and copy it to an external drive.
- Update Parallels Tools: Ensure your tools are up to date within Windows XP before the OS upgrade.
Most older programs in XP continue to run fine as long as the virtual hardware settings remain consistent.
