To be honest EP, we all have our opinions and I didn't know your situation when we started this.

Now I know the Laptop is not your own, my advice would be to leave well alone and not bother with MS patches, etc. it seems to me you know hot to avoid one error, that the machine does at least function as it is, the av software is not picking up any viruses. I'd suggest you wait till you talk to your friend.

You could end up creating yourself a lot of problems for no good reason here.
