please help me to overcome this problem

Sounds like a corrupted registry, are you able to boot into safe mode and run a system restore?

Or safe mode with command prompt and reset the registry using a file that may be available somewhere on the Microsoft Website...

If the problem is the registry, which it probably is, although may not

Yes I thought of this as well, my only fear would be that the CMD wouldn't launch even in safe mode.

But surely the system, especially Safe Mode, reads a 'default registry' of some sort when starting (i.e. even with exe association removed Windows still starts the EXPLORER shell), or at the very least executes specific files as EXECUTABLES, no matter the extension or association. Unless CMD is broken as well...

But that would be malware! Or at the very least an attack.

Hi 'prashant'kumar'sharma

We wonder if there is any luck your issue has been resolved.

As suggestion in all replies here I also think it might be caused by corrupted registry entry. system/registry might be the best way to get over this.

And in your case a full Antivirus scan is also necessary.

If you found your own answer for your issue, we would appreciate it if you could share with us so other user also can see it.
