Explorer’s tooltips can be useful but for some people they can be a royal pain in the arse. They take up valuable visible space and in small resolutions, can block your view. If you have massive folders, you can also find that windows wastes a lot of time working out what’s inside it…
You’ve got two options for disabling them.
Open RegEdit and navigate to HKEY_CURRENT_USER >> Software >> Microsoft >> Windows >> CurrentVersion >> Explorer >> Advanced. Then set “ShowInfoTip” to 00000000
Make a new file called disable.reg and put this in it:
REGEDIT4 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "ShowInfoTip"=dword:00000000
Then double click the file. It should prompt you and say “Yes” to that. To undo this just set “ShowInfoTip” to 00000001
