  • I own about every registry cleaner. None performs like RegDoctor.. It works fast and easy to use. I noticed major performance boost. I never noticed any performance with other cleaners. This one works. I just thought my system was in top notch shape. This program is a must-have for anyone that likes a clean fast system!!

    It is definitely one of the finest registry cleaners. It found and cleaned a lot of registry errors and invalid entries. It is very easy to use and the interface is great! It makes my computer run much faster and error free. This is a true 5-star program. Strongly recommend it.

    ---Jack Sun
  • Easy to use interface. Lots of search parameters. Shows you exactly what it found, unlike some others than just show you. Also it does delete what it says it finds. It beat out Registry Cleaner 2006(32), WinAso Registry Optimizer (20) and Registry Mechanic (22) in my own personal heads up testing phase. It found registry entries for Norton (which I deleted more than 6 months ago) that the others didn't. The total 92 errors found, were also totally different except for maybe like 10 entries that were exactly alike with all 4 programs. It seems the others just tend to clean the surface and this goes very in-depth. Anyway this by far is my new favorite!

FAQ & Help

1. Why do I need software for cleaning my Windows registry?

Your Windows registry is a critical element of your PC system, a large database that supports normal computer  operation. There are a number of causes of registry problems: more common causes are files left-behind after the un-installation or incorrect removal of software, hardware drivers that are either missing or corrupted, and startup programs no longer in use. Such issues lead to decreased PC performance, application errors and lockups, and computer crashes. A worst-case scenario can cause a fatal error, in which the hard drive must be completely reformatted prior to the re-installing of Windows and other software, potentially resulting in lost personal data and files. Windows registry problems have exploded with more recent PC use, as it becomes more and more common to both knowingly and unknowingly have new software programs downloaded to your PC. 

Having a computer systems professional provide a registry cleaning and repair service is an option. But that is an expensive approach, and one that likely would need to be used repeatedly over time. RegDoctor has put this process into an easy-to-use program that allows you to consistently maintain your system, before it develops into a bigger and more expensive problem.

2. What registry problems does RegDoctor detect?

Registry is large database that supports normal computer operation. It is a critical element of your PC system. RegDoctor will scan entire registry and detect problems related to Registry Integrity; ActiveX/COM, ActiveX/COM Subsections; File Extensions; Application Paths; Help Files; Microsoft Shared; Uninstall; Vxd; and Windows shortcuts.

3. After the scan, I don’t see the Fix the Problem button although RegDoctor found many registry problems. What can I do?

RegDoctor interface is designed for screen display in normal font size. If you are using large font for your screen display, you may not be able to see the Fix the Problem button. Three are two solutions:

  • 1.If you are using version1.50 or up, click on Action menu. You will see Fix the Problems command. Or
  • 2. Change the Screen display font. After fixing the problems, you can change it back to the font you prefer:

  • To adjust the font sizes, perform the following steps:

  • 1. Click the Start button and then click Control Panel. The Control Panel window appears.

  • 2. Click the Appearance and Themes category, and then click the Display icon.

  • 3. Click the Settings tab and then click the Advanced button.

  • 4. Click the pull-down arrow under DPI setting and then click Normal Size. The Change DPI Setting screen appears.

  • 5. Click the OK button.

  • 6. Click Apply. A General box appears.
    7. Click Yes.
  • 8. Click Close and then click Yes to restart the computer.

  • After you change the font size to Normal size, run RegDoctor again.

4. Why are there redundant entries in the list of detected programs after a scan?

A file can be referenced many times in the registry database for different functions. If the file is removed or becomes corrupted, the multiple references (pointers) will become invalid. RegDoctor will detect all the invalid references. This is why you may see same entries in the list of detected programs after a scan.

5. Can RegDoctor run automatically when I start my computer?

Yes. Check Run at Start-up under Options in Settings.

6. When I run the scanning, my system locks up or the scanning does not complete. What can I do?

It is recommended that you close down all the running applications when you run RegDoctor. Restart your computer. Close down all the running applications. Rerun RegDoctor. First, choose Quick Scan.

7. Some detected problems were not fixed. Why?

RegDoctor will usually fix all the detected problems. RegDoctor’s smart algorithm may choose to leave the error in place because multiple programs may be using a shared tool and correcting this would impact some programs. The threat level of the problems that were not fixed are usually very low.

To make sure RegDoctor will not fix a specific detected problem, you can also restart your computer and run RegDoctor again.

8. Why did a shortcut to one of my programs disappear from my desktop and how can I get it back?

If a shortcut was not created in a proper way, RegDoctor will identify and may remove it. If a shortcut you need disappears, you can easily recreate it. By recreating it correctly, the problem will not reappear and help the integrity of the Registry.
