Even as it appeared that Microsoft was moving slowly towards the operating system supremacy after launching its new OS update Windows 10, which has been appreciated for its latest features and improvements, it seems like the operating system is not free of bugs, after all.

For updating to Windows 10 operating system from Windows 8.1, 8 or 7, you can either upgrade the OS from the widget or download the official ISO file of Windows 10 from Microsoft website.

Though the first process updates the devices smoothly, running the ISO throws up a strange error message that reads, "Something Happened".

The error message abruptly stops the downloading process, just like the notorious BSOD (Blue Screen of Death) used to do in previous Windows versions.

Twitterati have already vented their frustration over the error message.
