Are Windows Repair tools safe to use?  

Windows repair tools are generally safe if downloaded from reputable sources and used correctly. They shouldn’t make any changes to your system without an explanation of how the fix works and giving a warning before applying fixes. 

However, remember to always read the instructions carefully before using any tool. It’s also wise to back up any data that might be affected, so you can revert back to the previous state if something goes wrong. 

In rare cases, poorly made Windows repair tools can cause further damage or delete data you need. Others do nothing at all despite claiming huge problems with your operating system.

That’s why the likes of Fortect perform a thorough scan of your system and outline exactly what it finds. The user can then make an informed decision about what to fix and see the results right away.

Unlike some tools, Fortect also uses an up-to-date database of fresh Windows files to replace any that are missing or corrupt instead of just removing any that are causing errors.

This ensures your system goes back to its intended state rather than losing functionality or getting patched over with unofficial files that can cause further instability. 

What Windows Errors are most common? 

Every PC faces errors from time to time. The most common Windows errors usually fall under these categories:

  • DLL errors – This occurs when a Dynamic Link Library (DLL) file that a program depends on is missing or corrupted. The program will crash and mention the DLL in its error message.
  • Driver errors – When a device driver, which allows the operating system to communicate with hardware devices, is outdated, missing or corrupted, it can cause varying degrees of system instability.
  • Registry errors – The Windows Registry is a database that stores configuration settings and options for the system and software. Errors occur when registry keys are deleted, corrupted, or left behind after software is uninstalled.
  • Application errors – When software or system applications fail to run or crash unexpectedly. This can be for many different reasons, including missing and damaged system files.
  • Windows Update errors – When Windows is unable to install updates or when the installation process fails, it can cause numerous problems for the operating system.
  • Network connectivity errors – When the computer is unable to connect to the Internet or other devices on a network.
  • Blue Screen of Death (BSOD) – When the system detects an error that could potentially cause damage to the computer, it will display the BSOD, which is a blue screen with white text that contains a detailed error message.
  • Boot Failure – When the system fails to boot at all or gets stuck in a restart loop.

While most Windows errors display some kind of message or error code, the average computer user might not be able to make sense of them. That’s why Windows repair tools are a great way to fix the problem automatically.
