Well, let the lost things pass away, but if you are naive and want to get it back, then try this little thing: Windows 8 CPU Meter.
Function:
Windows 8 CPU Meter is actually a 113KB ultra-small exe executable file. The full name of the file is: CPU-Meter
Windows 8 CPU Meter supports right-click menu, which can be set to start at boot, display disk usage, memory usage, always on the desktop, etc.
It's very nostalgic and worth playing and collecting. Anyway, it only costs about 100 KB.
