Windows 7: Lost access to C: drive and admin features

It would just be easier to reinstall. And leave the permissions as they are. Everything is set the way it is for a reason.

He evidently doesn't have a disk to reinstall.

Make a repair CD. Use Option 2. Download and make disk per instructions.
System Repair Disc - Create

Then use disk to do repair install. You will not loose any more of your files.
Repair Install
Sorry Hoppy, a system repair disk such as the one described in that tut cannot be used to do a repair install. Repair install requires a full fledged win7 install dvd.

The tutorial doesn't mention that. Then it is a boot disk to get into Windows. That is all.

You havent filled in your system specs so one doesnt know what brand PC this is. If this is an OEM machine (came with win7 preinstalled) there would be a recovery partition, visible or hidden. Every brand OEM has a Fn key to launch recovery from that partition at boot, E.g. HP has F10. If you tell us what brand your PC is, I'll try and find the hotkey for you.

Another very simple option is to contact the OEM either online or via phone. They will ship the recovery disks for your particular model at a nominal cost.

Thanks, i'll see what i can do with your suggestions hope some of them work...

and i set the permissions because i had wanted to restrict normal users' access to C: drive, but i mistook 'authenticated users' as 'users' and affected all users, so it was set the way it is because of a mistake. i am one of the admins of the computer because it is in my house... i really hope to find some help on this forum, I really need it.

Hopalong X, I do not have a disk to reinstall. that is correct.

Bill2, i forgot to include my sys specs... i'll do that within 24 hours ... i still have a biology exam tmr x[

but i think mine is a Lenovo OEM computer. i tried various recovery methods from the lenovo recovery 'interface' except the 'reset hard disk to factory installed state' one, and recovery points did not work, to my disappointment. I think there are infinite files that cannot be recovered (C: drive is not accessible... ) and i can only ignore one of them with one recovery point.

I am using an ext hard drive now... but i still can't initiate downloads from google chrome, haven't tried firefox/IE.

from my biology exam, you'd know i'm still a student... so i'll keep bill2's last suggestion as a last resort


But to be honest, how can such a trap/paradox exist in the advanced windows 7... although i know i shouldn't have done it on the C: drive... too harsh, i admit

I wonder if even resetting the hard disk will work... might not be allowed access either. Same goes for recovery disks.

UPDATE:
I also tried using CACLS but i cannot open an elevated cmd, so no access. Not even in safe mode.

Hope someone - anyone - can help me!

Thank you all, for the suggestions!

Kyrios, the only thing that looks like it'll work for you is in fact that "reset hard disk to factory installed state". This'll wipe any user data, so if you have important stuff on this computer, you need to try recovering it using something like an Ubuntu live cd. Its a freeware, you can download it, burn to dvd, then boot off it and see if it lets you browse to your files.

Lesson learnt is dont fiddle unnecessarily or at least till you know how to bounce back. And chill, we all burnt our fingers that way some time or the other...The other lesson is always keep important data backed up, best on an external hard drive.

Don't mess with the permissions at all. Removing Users or Authenticated Users, will foobar the whole system. Both are REQURIED. And Both only have at most read access for any marjor part of the system, without the ability to read, could not even log in. If you want to restict what a user has access to, you need to avoid messing with the WHOLE drive. Just limit the permissions on the data that needs to remain private.

Second, In Windows Vista/7 the account you create is part of the Administrators group. However, until you elevate (UAC prompt for example) that account appears and is restricted to the Users group.

Greetings,

I understand that it is my fault to even touch the permissions of the whole drive...
Thank you for your suggestion, Bill2. I will see what i can do to backup my stuff before i reset.

Logicearth, i know... it is a terrible thing to do... and thank you for the information.

Thank you all who replied...

Thank you for the help, i'll keep you guys updated so this thread can maybe warn others who made this silly mistake also... though i doubt if any exist.

What about connecting up an external USB DVD Drive, borrow a Windows 7 DVD from a friend and try a repair install after ensuring you can boot from your USB in BIOS?
