scusate c'è una persona gentile, che potrebbe tradure in italiano questo scritto.
grazie forse ho trovato la soluzione al mio probblema i tastiera.
1) go to C:\Windows\System32\Regedit32.exe
2) Click on Edit -
3) Type in kbdclass (be inventive here as I know you cant type. Copy this
name from c:\windows\system32\drivers\kbdclass.sys - right click and click
rename. Then just copy the 'kbdclass' - this can then be pasted in the
regedit box)
4) Search through for as many Upperfilters you can find.
5) They most likely have 2 lots of drivers associated with it eg 'tphclhs
kbdclass'
6) Double click the 'Upperfilter' and delete the other entry except
'kbdclass'
7) Search for all instances of this and change them
8) Go to device manager and uninstall your keyboard - then 'scan for
hardware changes'
9) Restart
