Hello Trond Gunnar Raa,
Thank you for posting in Q&A forum.
1.Use Disk Cleanup:
• Open the Start Menu, search for "Disk Cleanup," and launch it.
• Select the temporary files you'd like to delete and hit OK. Confirm by clicking Delete Files
2. Use Safe Mode:
Sometimes, deleting files in Safe Mode can help. Restart your computer in Safe Mode and try deleting the temporary files again.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
