Cleaning the registry can help improve system performance (albeit marginally) and avoid software conflicts.

The registry is the skeleton of the operating system. It consists of many parameters that govern how Windows works. Over time, the registry becomes littered with traces of various programs. This is not to say that this significantly reduces the performance of the computer. But we can say that conflicts arise in the work of the software due to this. Therefore, the registry must be cleaned periodically. This can be done using specialized software or manually.

Cleaning With Utilities

We recommend starting with this method since the number of keys in the registry exceeds thousands or tens of thousands. First of all, it takes a very long time to clean it all out yourself. Secondly, you can accidentally delete an entry that the system needs to function correctly. So leave this to the program. She will cope with the task in 99% of cases.

You can use any product designed to clean the system. They all work according to similar algorithms and differ little from each other. The whole difference often comes down to advanced functionality that optimizes system performance in other areas. For example, Advanced System Care can clean the registry and remove duplicate shortcuts and folders, defragment hard drives, get rid of spyware, and so on. But keep in mind that along with the growth of capabilities, the load on the system increases. Therefore, such tools are more suitable for owners of rugged PCs.

If the above functionality is redundant for you or you own a weak computer, you can use highly specialized programs. For example, CCleaner. How to use? It’s effortless: no matter what you choose, install the software and go to the registry tab. Run a scan and get rid of the errors found. It is recommended to agree to a registry backup, which will be offered by the utility itself. In this case, if a problem occurs, you can roll back the settings.

Manual Cleaning

If you are sure that a particular problem caused by a conflict in the registry has not disappeared after a software cleaning, you can delete any key yourself. To do this, follow these steps:

  • Press the key combination Win + R and in the field that appears, enter the command regedit
  • A registry window will open. Create a backup first. To do this, in the upper left corner, click on the “File” menu and select the “Export” item. Select the location where the .reg copy will be stored. 
  • Then go to the HKEY_CURRENT_USER branch under the Software section. Here you will see all the entries related to each program that is or has been installed on your computer. Unwanted entries can be deleted using the Delete key.

You can also use the search. With the registry open, press the key combination Ctrl + F, and in the window that appears, enter the name of the desired utility—for example, Skype. The registry will display all records in which this name appears. We also delete them using the Delete key.
