When I type t, i get 4f, when I type y, i get 7j, when I type letter o, I get 9, when I type g, i get r,when I type letter h, I get u. when I type letter e, I get a small window showing up and containing the letter n.

Hi,

My Dell laptop developed HDD issues a while back after I had upgraded it from Win 8.1 to win10. I had to buy a new Hdd n reinstall the Win10 but my software person didn't reinstall my laptop's win10 from MS server but got me a Win10 pro from a network that
i'm not a part of. I was unaware of all these things until the OS started asking to be activated. But my laptop had a genuine windows os before I had to change the hdd. I learnt I could still reinstall my original windows10 by downloading from the Ms server.
I have downloaded the ISO from Microsoft website unto my system but I don't know what to do next. I'm wondering if ican just run that directly and if it would recognize my hardware as one which is re`g`i```````````tered on the server and reinstall my original
win 10 and still retain my files/documents or if I should backup my files, create a bootable usb from the iso image and then do a clean install.

Secondly, my system has bee`n` behaving fun`n`y for some 2 weeks no`````````````w. it wo`u``l``d ``j`ust` s````````t`art typing this strange ``````````````````````````th`ing on `its own.```````````````````````````. I thought it was a malware on it n ran
