I'm not sure if this works, but you can give it a try:
Log in as administrator or user with admin privilages, if you haven't already done so.
Check you system time. Lets assume it is 10:50 PM.
Open Command Window and then type in the following:
Code:
at 22:52 /interactive "cmd.exe"
If your system time is 1:00 am for example, you shud do:
Code:
at 1:02 /interactive "cmd.exe"
Add 2 minutes to the system time. Hope this is clear.
Then close command prompt.
Now, press Ctrl+Alt+Del and then end the Explorer.
Then wait for 2 minutes, roughly. You will see another Command Prompt.
Type in "explorer.exe" in your new command prompt. You should be logged in as system user, and not your user.
Now, navigate to the folder and try accessing it. If the data was not encrypted, you may have some luck. Not sure this works, but you can give it a try.
Also, if the above procedure does not work and if your data is critical, you may consider buying "Advanced EFS Data Recovery" which might help.
