Honours: #85 - Top Rated (Today) - Howto & Style - Australia. How to Repair a Corrupt Windows 7 Installation. Every operating system needs an occasional repair job, and Windows 7 is no exception. Whether the source of the problem is corrupt data, a particularly brutal piece of malware, or some other serious issue, you'll occasionally have to reinstall your copy of Windows. With Windows 7 you can perform an in- place upgrade installation to repair a flaky existing install. Though technically designed to upgrade older Windows operating systems like Vista, the in- place upgrade installation option can also be used to repair an existing installation of Windows 7. A few other limitations come up later in the article, so be sure to read the entire guide thoroughly before attempting to repair your corrupt copy of Windows 7. Includes various tools: bad sector repair tool, test speed, S.M.A.R.T. Is the hard disk.Performing a repair installation should be your last resort, and you should consider it only if you have already removed spyware from your PC, reinstalled your drivers, and unsuccessfully tried to restore from an earlier (working) version of Windows 7 using System Restore. The first step is to back up all of your critical files to an external storage device. Though the repair process is unlikely to fail or to render any of your files unrecoverable, it's always a smart idea to back up your data. You can always reinstall them after completing the repair process; but since you'll be initiating this process from within Windows, you need to remove any security applications that actively scan files. You should also download and store all of the drivers that your system needs to function- -especially the network controller, which tells your network adapter how to access the Internet. To do this, click the Start button, and in the Search field type Folder Options; then press Enter. In the Folder Options window, click the View tab and select Show hidden files, folders and drives; then click OK. Select the Disk Cleanup utility in the lower- right portion of the menu, and select Clean up system files. The Disk Cleanup utility should take a few moments to rescan the drive. Next, click the More Options tab, and select Clean Up in the 'System Restore and Shadow Copies' section at the bottom of the menu. In the dialog box that appears, click the Delete button; then navigate back to the Disk Cleanup tab, confirm that all items in the Files to Delete list are checked, and click OK. The Disk Cleanup utility should clear out outdated system files, temporary data, and other digital detritus. Depending on how much junk data is on your drive, this step may take anywhere from a few seconds to a few minutes. Open the C: drive again, and double- click the Windows folder. Scroll down the list of folders and delete any files in the Prefetch and Temp folders. Be sure to delete only files within those two folders and not the folders themselves. Next, navigate back to the C: drive, and double- click the Users folder. Within the Users folder, double- click first the folder for your particular username, and then the App. Data folder (if you don't see the App. Data folder, you must not have selected 'Show hidden files, folders and drives' earlier), the Local folder, and finally the Temp folder. Delete all of the files in this Temp folder as well; then restart your system.
