Earlier today I was downloading Carbonite files from one computer to this one. Somehow I messed up and stopped download. Desktop disappeared and when I tried to do a system restore tonight, I got the title message even when I went back to 3 May 2012. What did I do and how can I fix it?

Earlier today I was downloading Carbonite files from one computer to this one. Somehow I messed up and stopped download.

I have Windows 7 operating system.

Hi, Please try the following steps: 1) If you can access cmd, you can reset the security settings in Windows 7 with the following command: "secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose" (no quotes.) NOTE: If you can't access cmd when logged in, use this guide System Recovery Options. You can get to the command line when you access the System Recovery Options screen. 2) This command seems to give the ownership issue a kick up the backside, even though it seems nothing has changed. Go to Explorer, right click on C: and go to Properties. 3) Go to the Security tab and then Advanced. 4) Go to the Owner tab. Now you should be able to click Edit. 5) If you don't have Administrators in the list under where it says "Change owner to:" then go to "Other users or groups". If you do, go straight to step 7. 6) On Others users or groups type in "Administrators" (no quotes) in the bottom box. Click Check Name and then OK. 7) Click Administrators and then OK. You've now given yourself ownership of C:! (As long as your account is an Administrator, that is.) 8) Click OK on the "Advanced Security Settings..." window to get back to the Properties window. You should now have a list of the Permissions and so on where before you only had something about how you couldn't view permissions. Progress, eh? 9) You may need to add in the Adminstrators group to edit their permissions. To do this, click "Edit" and then "Add" and type "Administrators" (no quotes) in the bottom box. Then hit Check Name and then OK. 10) Click Administrators in the list and tick the box in the Allow column next to "Full control". 11) Click Apply, you'll likely get a bunch of error messages about how this can't be applied to some files and folders. Just OK through them all. Once done, you should have access to your C: drive once more! Hope this helps. Vincent Wang TechNet Community Support
