if you don't want your stuff being changed then...
don't let others logon under your account
don't let others logon under an administrator account
do make user accounts that are limited and have others logon under them
then spend some time reviewing the word 'tact'
after that spend some time googling user accounts so you can understand how unreasonable your request is to have someone logon under your account and expect them not to have the ability to change things.
its like asking that others can drive your car but they can't use your gas.
