1. Repair missing DLLs with DLL repair software

DLLs are libraries containing sensitive data that should not be manipulated by the user unless he really knows what he is doing, in which case it is recommended to back them up.

Therefore, the safest alternative at the moment is to use third-party tools that can recover your recordings for you, and the best on the market is Restoro, a tool that automates the entire process.

DLLs and Registries are valuable data libraries that Windows uses to function properly.

As a result, damaged or missing DLLs or registry keys can be a major cause of crashes, lockups and error messages, and even prevent you from running Windows software and functionality in general.

Unfortunately, registries and DLLs are piles of data that are difficult for even advanced users to configure properly without advice or even help from Microsoft.

Moreover, restarting the Windows operating system is one of the few really effective solutions to correct these errors, but this solution has too many drawbacks.

To avoid all this, you can always turn to third-party automated solutions, and few are as good as Restoro. It automates almost every aspect of the PC repair process, from scanning to the actual repair.

Follow this short guide to find out how to restore your PC’s optimal performance with Restoro :

  • Download and install Restoro
  • Start Restoro
    • Restoro is now collecting data about your PC.
  • Wait until it finds issues with system stability and possible malware infections.
    • Once the scan is complete, Restoro will show you an overview of the current status of your PC.
  • Click on Start recovery.
    • Restoro will now start downloading and replacing the damaged registries, DLLs and other corrupted files found during the scan.
    • This is made possible by online libraries that are used for comparison and replace damaged data with their functional equivalent.
  • Restart your PC for all changes to take effect.

Now your computer should be working fine and you won’t have to worry about slow response times, BSoD errors or anything like that.

Disclaimer : Some specific actions require this program to be updated from the free version.

The System File Checker (SFC) is a tool built into Windows for repairing damaged or missing system files. The SFC scan can correct various DLL errors.
