Keyboard and Mouse Issues

The following two keys of my Dell Inspiron laptop is not workin ;
1) 'Delete' key
2) 'Down arrow' key.

My laptop's system drive is 'C', one of the system folder in drive 'C' is occupying too much of space. I am pretty sure that there are plenty of unnecessary data and file. How can I find which one to keep and which one to delete, pls advice.

when i plug in a usb mouse or dongle for wifi or bluetooth mouse they do not work .In device manager i get a code 10 message windows cant start device . I have tried updateing driver ,best driver already installed. Your driver updater doesnt find anything .
can you help please

Bonjour, suite à une mise à jour de Windows (?), mon clavier Bluetooth n'est plus reconnu. Dans "paramètres", il est indiqué : installation bloquée par stratégie de groupe.
Que dois-je faire pour réutiliser mon clacier normalement ?
Merci par avance
Cordialement

Sometimes my computer freezes and I have to wait awhile to type again. Is there a solution for this? This happens in Internet browsers and Microsoft Word.

I am a long time professional and I am actually quite tech savvy. I use the computer very very clean (obsessive level) But my mouse started to lag recently. I have downloaded Auslogics Pro (thats how we met) Even though I liked the software, it didnt solve the problem.

My laptop is Dell Vostro with i7 and 8GB Ram. Fairly new one (less than 1 year) But even with a simple operation (like opening Skype) it starts to level up fan noise and mouse starts to flicker, lag from time to time.

I formated everything on my computer (because this was not the case until very recently) but even that didnt help.

What can be the reason?

Keyboard built-in has been made mostly garbage, by enemy espionager. I do not seem to have backup to fix it nor for resetting Windows.
(These words are from a USB keyboard.)

Why are some device drivers ignored and what are the 2 devices that are ignored as shown on the Review screen? I am having alot of trouble with my wired keyboard. It will light up but not enter key characters on all USB ports except one (which is on an external hard drive). Is that one of the ignored devices?

In the registry under system the i 3048 is missing and keyboard does not work hit a key and it sticks i have to use a second keyboard
