    Can I use one serial number on two computers?

    Please note that one SN could be only used on one computer at the same time. If you want to use it on the second computer, I'm afraid that you should buy a new SN or uninstall the program from the current computer then install it on a new PC and activate it using your SN.

    Registry Confusions

    What is Windows Registry?
    The registry is the central hierarchical database used in Microsoft Windows operating systems to store information necessary to configure the system for one or more users, applications and hardware devices.
    It contains settings for low-level operating system components as well as the applications running on the platform: the kernel, device drivers, services, SAM, user interface and third party applications all make use of the registry. The registry also provides a means to access counters for profiling system performance.

    Why should I use a registry cleaner?
    Every time you install an application, new registry entries will be created. These entries should automatically be deleted when you uninstall the application. However, you will find that some applications fail to remove their own registry entries. These entries then become obsolete, which burden the Windows Registry over time. This invalid data accumulate in the Registry, slowing Windows down, crashing PC from time to time and so on. Thus, it is strongly recommended that you periodically clean your Windows registry so as to keep your computer in peak performance.

    Technical Troubleshooting

    Will Registry Optimizer Free backup my registry before I choose to cure?
    When you cure the discovered errors, a backup file will be created automatically and instantly (This process is fast because it only backs up those registry entries that will be changed.). Click restore button in the top right corner, a restore center can help you reclaim the data deleted. So, it is 100% safe and reliable to use.

    Why the scanning didn't find any error?
    It appears that the program hasn't been exited properly before downloading and installing the update. You can uninstall and then re-install Registry Optimizer Free.

    Why Registry Optimizer Free still can find some deleted files, though I have scrubbed the drive?
    If you have scrubbed the drive, Registry Optimizer Free still can find some deleted files names, however the content of these files has been destroyed. These files can be restored by Registry Optimizer Free, but they will become unavailable.

    What if I have other questions?
    Please feel free to contact us at [email protected], and our support team will reply as soon as possible within one working day.
