My mom is afraid that if I get an airsoft gun, I'm going to shoot at people, and cars. How do I convince her?
It sounds like you are logged in on a limited user account instead of an account with administrative privileges. You won't be able to end SYSTEM processes as long as you are a limited user. Have an administrator log in and go to control paneluser accounts and change your account to administrator instead of limited.
if its abayonet fitting its as easy as changing a light bulb, BUT its illegal to do it. a corgi gas fitter will ensure that the new appliance is safe as well as testing gas pressure etc. it may seem expensive to pay a corgi fitter but you will know the installation is safe. if u been given cooker then spending a few quid on fitting is the best move. if it was a brand new cooker i might chance it but not with a used one
