Update, Scan and Troubleshoot to Fix Windows Explorer
1. Rule out potential corruption or other problems caused by malware by running full scans with your antivirus and antispyware programs. Before running the scans, make sure the programs are updated with the latest definitions. Alternately, run the scans while in Windows Safe Mode to prevent potential viruses or other malware from interfering with the programs.
2. Download and install any outstanding Windows updates, including service packs. To do so, visit the Microsoft Windows Update Web page (see Resources) and use it to run a scan on your computer for needed updates.

3. Restart Windows Explorer if the taskbar does not appear on your Windows desktop (and you're not using the auto-hide feature). To do so, press CTRL-ALT-DEL to start the Task Manager (depending on your operating system, you may need to click 'Start Task Manager' after pressing those keys). In Task Manager, click File, click New Task (Run), type Explorer in the Open field, and click OK.
4. Determine if recently installed software is interfering with Windows Explorer. Although most programs will play nicely with Windows Explorer, occasionally problems can occur that prevent Windows Explorer from running as it should. If you recently installed one or more programs, try uninstalling each program (one at a time) to see if the problems with Windows Explorer cease. If they do, check with the program's developer for an update, fix or workaround.
5. Perform a System Restore if you cannot locate a simple fix for Windows Explorer problems. To access this utility, click Start, All Programs, Access, System Tools and then System Restore. Choose a restore point prior to the time when you started experiencing problems with Windows Explorer.

Manually Editing the Registry
1. Log in as a system administrator. You will need write privileges to the system registry, and you will not have them as a 'limited' or 'normal' user.
2. Click 'Start,' 'Run,' type 'regedit' and then click 'OK.' The registry editor window should appear. If you are given an error message saying you do not have sufficient privileges to edit the registry keys, you are not logged in as an administrator.

4. Browse through the many registry hives in the column on the left looking for keys that either contain incorrect information (a mistoggled setting, etc.) or should not be there.

6. Close the registry editor when you are finished editing the registry and restart the computer. If the computer will not start up or is no longer working properly, boot into 'Safe Mode' and restore the previous registry from your backup using the registry editor.
Using a Registry Cleaner
7. Download a registry-cleaner utility. Two popular registry-cleaning software suites are CCleaner and Advanced SystemCare. Both of these applications are available for download free of charge (see Resource links).
8. Perform a virus scan on the downloaded files and install the software. You will probably need to be logged in as an administrator in order to install and use the software, since you will require write access to a vital system component (the registry).
9. Launch the utility and follow the on-screen prompts to perform a 'quick' or 'in-depth' registry scan. It's usually best to perform an in-depth scan every time, since it will usually catch more errors and does not take significantly longer than the quick scan. If the software doesn't automatically prompt you to back up your registry, do it manually.
10. Look briefly through the list of errors generated by the registry scan and choose (with a check mark) the errors you wish to remove. Sometimes the scan will generate a false positive of an error that really isn't an error. You can tell the software to ignore this instance during future scans.
11. Click the 'fix' or 'clean' button (depending on the software you use), and the software will automatically remove or properly edit the checked entries. Restart your computer. If the software fixed numerous errors, you may notice your system starts up much more quickly.
