I've been given a computer by a friend and I'm sure it's over 5 years old, ADVENT make and running windows vista. I don't KNOW which internet explorer version it's running but recommends I update to version 9 (hopefully that'll help in aging this thing).

I've got a belkin surf n300 internet stick as it won't connect to the internet as a wireless device.

I'm tying to download Skype but everything seems to be going wrong.

I've followed instructions to update my windows
And can get as far as

Control panel > security > windows update

But when I try to update it comes up with

Errors found:
Code80072F8F


And this isn't recognised in the "get help" tab.

When I try to GO online and update my internet explorer it recommend internet explorer 9 but I cannot update as all pages I try to open (even googles home page and microsofts homepage) I'm met with a tab reading

Certificate error: navigation blocked

I can either close the window or continue which isn't recommended and when I do continue the search bar TURNS red and another bar pops up saying

To help protect your security, internet explorer has blocked this website from displaying content with security certificate errors

I can choose to show blocked content but it absolutely refuses to let me update both my windows and my internet explorer.

Any solution would be highly appreciated Are the time and Date correct on the SYSTEM? 80072F8F indicates that it couldn't establish a secure connection, and the same applies for certificate errors- both can be caused by the time and date (or time zone) being incorrect.... I am an idiot. I NEVER even checked XD I'll check and change it now

Thank you so much for the tip!
