As some entries are deleted, they leave behind other references and some empty entries which are presented in next scans. This process may be replicated more than twice depending upon the Registry structure.
We recommend that you:
Run your Registry scan/clean cycle until your invalid registry entries are roughly 10 or less. The scan and clean process gets faster with each cycle. If you started with hundreds of invalid registry entries, this will greatly improve your computer’s performance.
Run your Registry scan regularly – at least weekly, or even every other day if you use your computer a lot.
In reality, every time that you install or delete software, view temporary files, even when you save certain files, you are making invisible changes to the Registry – the clutter and gunk that result in poor computer performance.
Therefore, it is recommended that you clean the registry from time to time to keep it streamlined.

During regular usage of the system, the Registry in which Windows and other applications store information can begin to hold data that is no longer valid. Such information points to a location on the hard drive where there was a file, which no longer exists. There may be several reasons behind these invalid Registry entries but such invalid links occur often because the programs uninstalled do not remove their registry entries completely or, the programs were not correctly uninstalled etc. These invalid entries eventually begin to clutter your Registry, slowing Windows down and causing other possible issues.
Invalid links are common in system Registry, and is always a good practice to regularly clean them. The Scan Registry section will scan the Registry finding these invalid data references.
Start the process by selecting Start Scanning Now. By default, all the areas prone to invalid registry entries are selected.
During the scanning process you can notice the Registry keys being analyzed. At any time you can abort the scan process by clicking the Stop Scan button.
Once you are through with the scanning process, the program displays the result window that summarizes all the Registry categories scanned and the total invalid registry entries found under each category. The issues found are divided into various categories so that you can easily get to know the issues under each category.
Scan Result displays under each category. Each category is divided under sub-categories that can be viewed by clicking on the small triangular button next to the category name. At the bottom left corner of this screen invalid registry entry Details option is linked to a new window that details each and every invalid registry entry found under that category. The entries in the new window describe the name of the invalid reference and the path/location referring to it. By default, these invalid Registry entries are selected for repair. Uncheck the box to un-select the entries that you do not want to be repaired. Please note that any entry unselected may impact the final result of the cleaning and the overall system performance boost.
Right-click menu options on the invalid registry entry detail window:
Before fixing the issue entries you can review them individually and if you find any entry to be excluded from the list of invalid entries, uncheck the box associated with it. It is advisable to be extremely careful when manually changing the Registry entries. If the list of corrupt entries is more, you can scroll-down the bar to view all the entries in the list or opt to maximize the window.
Click on Fix invalid registry entries to start the removal of invalid registry entries, resulting in an invalid registry entry free, smooth and stable computer.
Registry plays a key role in the configuration and control of Windows operating systems. It is the repository for both system wide and per-user settings. The data in the registry is stored in hundreds of keys and sub-keys. Windows and programs query the registry for information constantly. With passing time, as programs are used, installed and uninstalled, data is scattered all over the registry with numerous free blocks in between. Think of Registry database as a chart with rows and columns on a big sheet. Even when the data is deleted from a Registry block, it still maintains a reference to the next Registry block consuming the same amount of space that it occupied before. When new items are added to the Registry, they are added at the bottom of the chart. So over time, the Registry ends up with a lot of blank cells. If any of these blank Registry corrupt, it may pass invalid information to calling program causing system halt and slowdowns or can even cause a system crash.
Querying a Registry with fewer entries is faster. Furthermore optimizing the Registry makes the load time shorter.
How to optimize Registry?
RegClean Pro compacts Windows Registry to improve your computer's performance and eliminate registry fragmentation, giving you a fresh new registry without fragments. To optimize the registry, go to the Optimize Registry tab, which will state when you did your last Registry optimization or if you have not optimized it yet. There, click the Optimize Registry Now button to start optimization.
A confirmation dialog appears after you click the button, which states that your computer will restart automatically once the optimization process is complete. Please note that you should close all the open documents and applications before committing to optimization, as the system will restart once the process is complete and you may lose any unsaved data. Click on Yes to start the optimization process. When the process starts, a progress indicator bar appears as shown in the image below. Once the optimization process is complete, your computer will automatically restart to effect the changes.
RegClean Pro has been designed in such a manner that it is absolutely safe to clean and optimize Registry. In the rare case that you believe cleaning of Registry has caused any of the installed program to work improperly, or your computer is taking a lot of time to boot, or is running slow, or has affected your computer in adversely, you can always revert the state of your computer to the last known good configuration. The Restore function will help you to get back to your previous Registry stage and may solve the issue.
In Backup and Restore Registry section you can take backup in couple of ways:
Complete Registry backups can be taken manually by clicking the Take Full Registry Backup button. However, when you press the button One Click Optimization on the main screen, complete Registry is automatically backed up before any action is taken.
Whenever you scan and clean the Registry manually, after selecting the necessary Registry categories, the program automatically takes backup of these categories before removing their invalid entries. This may prove essential whenever you want to restore entries of such categories.
In the Partial Backup section, the backups are maintained by dates i.e. they are always categorized under the heads, Today, This Week, This Month, This Year, and Last Year.
How to Restore?
Simply select a backup record from the Full Backups or Partial Backups section and press on Restore. The Registry entries from the chosen date and time will be restored. However, if you find the section is piled up with old backup data, you can also delete them and keep only the ones required.
RegClean Pro allows you to configure settings as per your requirement for best and optimum output. The tabbed sections are mentioned below:

RegClean Pro has a section to create Exclusion List. If you want to exclude a path from Registry scanning, you can add that path into this Exclusion List. Remember that if invalid Registry entries are created under the path excluded by you, RegClean Pro will not be able track those registries and the sole purpose of optimizing your system Registry will fail. Therefore, it is suggested that you should be more careful before excluding Registries.
For excluding a Registry, you just need to click on Add Entry and select the section that you want to add in exclusion list. The drop-down list provides the name of the hives. To be more specific, mention the complete path of the Registry key in the next box given, Specify Registry Entry. Press OK to add it to exclusions. You can even delete an entry from the exclusion list just by selecting the entry and clicking on Delete Entry button.
Skip issue due to removable media: When you install removable drives, it creates certain Registry entries. When the drive is removed, Registry references will become invalid as they will link to the drive not found on your system. However, at a later time if you are certain to attach the same drive again, we suggest not to delete such invalid registry entries because in that case you may have to reinstall the drivers for the removable drive. Simply, check the option to skip invalid registry entries displayed in such condition.
