I hope I'm in the correct section. I was refered to this site by another. Great community.
To the problem. I was trying to set up a guest user account for others to use my laptop for school work and I tried to block areas of my computer by editing the permission or security. Without paying attention, I blocked full use of 90 percent of my computer to ALL user, including Admin. . At every turn that I make to change or add anything, I get a message " Access denied". I can't even get into my C: drive nor play a game ( game createts logs which is in the c: drive ). At the control panel, all access to change things have a shield next to them which nulls the buttons.
I tried Sys. restore but I get the security shield which nulls the button and I tried from F8 to restore to another date which it only had one date to choose from but I got a error message 0x80070005, then a second message about not with in the parameter 0x800700057.
All I have are movies, albums and resumes ( some games ) so I don't mind loosing all that and starting from scratch. I would rather not, if possible. But MS doesn't give discs any more so I can't reinstall from an external source because everything is built in. And MS charges for help. No job, hence the reason for the resumes.
If anyone could help with advice or log on to my computer remotely, I would deeply appreciate it. I am at my wits end and alittle frustrated because of my own stupidity. I thank those who have tried to help me and those in the future. And if some day we should meet, I would like to buy you a beer or coffee.
I hope I was clear on my discription of problem. I have a toshiba laptop c650d satellite, win7 home premium, pk 1, processor AMD C-50. Thank you for your time Leo.
