Applying this set of registry entries works for me without resetting the rest of the user settings:

Ofc this is applied when HWiNFO is completely stopped, even in the background.
This fixed it for me:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\HWiNFO64\Sensors]
"WndTopX"=dword:000006d7
"WndTopY"=dword:0000025a
"WndBottomX"=dword:0000091a
"WndBottomY"=dword:00000511
"WndStyle"=dword:9ccf0844
"Scaling"=dword:00000064
Put this in a .reg file and run...
