Important: System Restore will not revert any of the non-system files like documents, email, music, etc. to a previous state. These types files are completely unaffected by System Restore. If your intention with this tool was to recover a deleted non-system file, try using a file recovery program instead of System Restore.

Important: While performing check disk on the hard drive, if any bad sectors are found, then check disk will try to repair that sector. Any data available on that sector might be lost.

Custom Install Disclaimer: If you don't format the hard disk during installation, data files are saved to a Windows.old folder on the partition you installed Windows 7.  However, you should still back up the files. If you have data files that are encrypted, you might not be able to access them after installing Windows 7. If you've backed up your data files and then restored them after installing Windows 7, you can delete the Windows.old folder.

I hope the above step helps. If you need further assistance on this particular issue or any other Windows related issue let us know and we will be glad to assist you.
