Hi,
Would you please let us know which icons meet this issue, the desktop icons or the items in Modern UI?
I would like to suggest you try the following to check the issue:
- Run msconfig and disable all non-Microsoft services and startup items.
- Start Task Manager and check if there is any process cause high CPU or Memory usage.
- Switch to another account and see if it works.
Thanks.
