When upgrading to 4.0, a few issues have workarounds, and they are listed below.

• If you still see the old icon when you search for nTop in the Start Menu, it is caused by Windows caching icons. To fix it, follow the steps in the link below.
  • Icons not showing Correctly in Windows Search. 

Note: nTop didn’t write the article in the link above, and this link will take you to a different website

• If you still see the app name as nTopology and cannot see Recent Files when you right-click the nTop icon from the taskbar, we recommend unpinning the old nTop icon and pinning the new nTop again to fix it.
• If you are missing a nTop icon from the taskbar, you might have to Pin it again by right-clicking the ntop.exe either from Desktop or your installed location, for example (C:\Program Files\nTopology\nTopology) and select Pin to taskbar.
