What if I can't run the executable suddenly under Windows? Exe is not associated?

Q: My computer is a Windows 7 operating system. All the executables suddenly failed to run a few days ago, prompting that "the file does not have a program associated with it to execute." Even if you enter a program to run in the Run window, it displays "Unsupported Interface". What should I do?

A: You can enter the following content in Notepad:

////////The following is the contents of the notebook, excluding this line /////////

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT.exe]
@="exefile"
"Content Type"="application/x-msdownload"
[HKEY_CLASSES_ROOT.exePersistentHandler ]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"

////////The above is the contents of the notebook, excluding this line /////////

Save as a ".reg" registry file (arbitrarily named, eg exe.reg), then double-click and import the file.

OK, let's try again, is it fixed? Soft media will include various options for system repair in the future Windows 7 optimization guru and Rubik's Cube, which will include these.
