Hello, SolLuxNP
Welcome to the Microsoft community.
When .exe files are not opening or working properly on your Windows laptop, it usually indicates an issue with Windows itself or with the specific application settings. Here are several steps you can take to diagnose and potentially resolve this problem:
- Check for Malware
Malware or viruses can sometimes cause .exe files not to run. Running a full system scan using your antivirus software can help identify and remove any malicious software that might be causing the issue.
- Use the Registry Editor
Incorrect settings in the Windows Registry might prevent .exe files from opening. You can try fixing it by modifying the registry:
- Press Windows + R, type regedit, and press Enter to open the Registry Editor.
- Navigate to HKEY_CLASSES_ROOT.exe in the registry tree.
- In the right pane, double-click on (Default) and set its value to exefile.
- Navigate to HKEY_CLASSES_ROOT\exefile\shell\open\command.
- Double-click on (Default) in the right pane and set its value to "%1" %*.
- Close the Registry Editor and restart your computer.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
- Run System File Checker
Corrupted or missing system files can also cause .exe files not to execute. Running the System File Checker (SFC) can repair these files:
- Open Command Prompt as administrator by right-clicking on the Start button, selecting Command Prompt (Admin) or Windows PowerShell (Admin).
- Type
sfc /scannow and press Enter.
- Wait for the process to complete and then restart your computer.
- Change Your Default Program Settings
Sometimes, .exe files might be associated with the wrong application, preventing them from opening correctly. You can reset the default program settings for .exe files by:
- Going to Settings > Apps > Default Apps.
- Scroll down and click on the
Choose default apps by file type link.
- Locate
.exe in the list and set its default app to the correct application (usually, this should be Windows to handle .exe files).
- Create a New User Account
If the problem is specific to your user profile, creating a new user account might resolve the issue. You can do this through Settings > Accounts > Family & other users > Add someone else to this PC.
- Perform a Clean Boot
Software conflicts can also prevent .exe files from opening. Performing a clean boot starts Windows with a minimal set of drivers and startup programs, which can help identify if background applications are the cause:

Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.
