how to interpret a hidden value registry key detected by CCE

Hallo to everybody.

A CCE scanning in my notebook has found a hidden value in Windows registry with a high level of risk. I’ve tried to search it in Web, without any results.

I’d like to know how to get some information in a possibly threat like this, even for the future.

My notebook’s got W 8.1 installed.

The value found is:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\ Windows\CurrentVersion\RunOnce\{C1553357-8556-48BA-BE8D-60C97DCFDAAD}

Thanks in advance for your suggestions.
