What is the reason for the system to prompt like this?

The screen prompts that no operating system can be found to boot.

First of all, unplug all USB drives and portable hard disk devices on the computer, and if you want a desktop, please check whether the hard disk data cable and power cable are connected.

If there is no problem with the wiring, this prompt still appears, that is, the operating system on the hard disk is damaged.

If the computer has been backed up or is a genuine system, you can try to restore the factory system; Otherwise, you can use the system disk to boot the computer and reinstall the operating system, which can solve the problem.

Only administrators can register as local computer accounts. The key service also allows administrators to remotely install personal information exchange (PFX) files for computers.

If this service is stopped, Auto-Enrollment will not automatically get the default set of machine certificates.

Recently, a number of software startup errors have appeared: "Unable to locate program input point except handler4 common on dynamic link library".

The situation in which this prompt appears is: Windows XP system; Software includes: Windows Live Writer 2009, Windows Messenger 2009, Firefox and other very new versions.

After this prompt appears, click OK and it will not affect the use of the program. The reason for this problem is actually Microsoft's own problem. It's a legacy of Microsoft's Vista.

In the Vista system, there is a very cool feature, which is "program thumbnails", which has a bit of a 3D effect, and this function calls this library, and it references the except Handler4 common function in .

However, in the XP system, the version that comes with the system is different from that in Vista and does not have this Except Handler4 Common, and as a result, the error message "Unable to locate the program input point except Handler4 Common on the dynamic link library" when starting the program.

Workaround: Add C: Windows System32 under .

Change the name, e.g. to .

PS: This is the answer to copy and paste.

Copy one to the system and you're good to go.
