How to solve the problem "This file does not have a program associated with it to perform this operation" after Windows 10 update

Introduction:
As the operating system is updated, sometimes we will encounter some problems , one of them is that when using Windows 10, when we double-click to open a file, the system will prompt "The file does not have a program associated with it to perform this operation." This situation is usually caused by file association errors, but there are some simple steps we can take to fix the problem.

Cause of the problem:
In Windows 10, each file is associated with a specific application. When we double-click to open a file, the system will determine which program to use to open it based on the extension (such as .txt, .docx, etc.) or file type. However, when the system is updated, it may cause some file association errors, that is, the system cannot find the associated program to open the file.

Solution:
The following are some methods to solve this problem. You can choose the appropriate method according to the situation:

Method 1: Reassociate the file type

1. First, right-click the file in question and select "Properties".
2. In the properties dialog box, find the "Open with" section and click the "Change" button.
3. In the new window, you can select an existing program to associate the file type with, or click the "Browse" button to find a specific application.
4. After selecting the correct application, click the "OK" button to re-associate the file type.

Method 2: Use default application settings

1. Open the "Settings" menu (Win key I), and then click "Apply".
2. In the left navigation bar, select "Default Apps".
3. In the right window, scroll to the bottom to find "Select default apps by file type", click here.
4. In the new window, you can find the file type in question and select the specific app to the right of it. If you can't find the right app, you can click "Get other apps from the Microsoft Store" to download the appropriate program.
5. After closing the window, the system will automatically re-associate the file type.

Method 3: Repair through the Registry Editor
Please note that changes to the registry may have an impact on the system, please make sure to back up the registry file before proceeding.

1. Press the Win key R and enter "regedit" to open the Registry Editor.
2. In the Registry Editor, locate the following path:
   HKEY_CLASSES_ROOT.File Type
   For example, for a .txt file, the path should be HKEY_CLASSES_ROOT.txt.
3. Under the path of the selected file type, look for the "default" key and make sure its value is the correct file type (e.g. txtfile for .txt files).
4. If the value of the "Default" key does not have the correct file type, right-click to change the value data to the correct value.
5. Repeat the above steps to ensure that the "default" keys for other file types are correct.

Conclusion:
When we encounter the problem of "This file does not have a program associated with it to perform this operation" after Windows 10 update, you can try to use the above method to solve it. Re-associating file types, using default application settings, and repairing through the Registry Editor can all help us re-establish the correct file association so that the system can open the file correctly. However, be sure to back up and exercise caution before changing and manipulating the registry. If the problem persists, it is recommended to seek professional technical support or official Microsoft support for further assistance.
