How to re-set P.C back in time to recover lost files?

Hi...I was using an interfaced program. I made some changes re-setting it back to default options as the manual changes I made seemed to have made it run too slow. On re-start for the changes to take effect, I have lost a huge amount of data. IS THERE ANY WAY I CAN RE-SET MY P.C TO SEVERAL HOURS BEFORE SO I CAN GET MY DATA BACK?

How to re-set P.C back in time to recover lost files?
Using system restore will not bring your files back. It only resets the operating system files and settings back to where they were at a given "restore point".





If all you did is change a program back to its default settings (I have no idea what an interfaced program is) it shouldn't have deleted any of your data.





What may have happened is the folder you saved your data to originally is not the "default" folder for the application, so when you try to open a file it is not in the "default" folder. But it should still be in the original location you saved it to.





Do this: Open Windows Explorer and go to My Computer. Now click on the Search button at the top of the window and select "All Files and Folders".





Enter the name of a file you can no longer find in the first box on the left (a partial name will do). Also, make sure that "Search Subfolders" is checked in Advanced Options. Click on the Search button at the bottom and let the computer look for your file. If it finds it, the rest of your stuff should be there as well.





If it doesn't you data is probably gone and about the only thing you could do then is use a third-party program like Get Data Back to look on the hard drive for the erased files.
Reply:If you are using WIndows XP, you can use system restore(http://support.microsoft.com/kb/306084), but it will not restore data (ie, files in "My Documents)





If you deleted the files, look in the recycle bin, they could be still there (http://www.easeus.com/resource/recover-d...

Reply:Please explain what you mean by interfaced program.


What program, exactly, do you mean? Then maybe we can help. It is really bad to lose data. I feel your pain.
