title: What happens if I change the value of the control register cr0?
body: <p>I am reading about the Linux Kernel, and I learnt about the <code>cr0</code> control register that stores flags about <strong>paging</strong>, <strong>protected mode</strong>, etc.</p>
  
  <p>I was wondering, if it is even possible, what would happen if somehow I managed to change the value of <code>cr0</code> to modify flags?</p>
  
  <p>I don't want to ruin something on memory by disabling paging or anything, so I thought about trying myself, but I am afraid of what could happen.</p>
