i have windows 7 machine
i have two questions -
1. what should i do to restore my machine to a previous or the last working state so that if i have any virus or something wrong on my machine i can bring it back to the last successful state
2. sometimes at my work, after the systems/security group does some patches, and i guess they do a kind of restart on our machines, and after logging in(after the patches are applied or the next day) , some of the applications like googlechrome, internet explorer, windows-word etc gets opened up automatically, how is that happening... what is it called
thanks a lot...
