Hi their I have opened up the system32 folder and the files were hidden I aksed the computer to view them how can I get them hidden again thanks

On the top bar click 'Tools' then 'Folder Options'

Click on the second tab (View) and about half way down the scrollable window you should see a radio button with

'Do not show hidden files and folders'

Select that, click Apply then Ok

Sorted!

Cheers

No worries!
