ARPCache

Would someone be able to explain to me what the following files are (what do
they represent):

{125F0ACC-D3FC-402B-8096-2F6E46D00D}
{45D68F08-56AO-4412-BB0F-8492BE978AC7} etal

They are located in: (HKEY LOCAL MACHINE)
HKLM\Software\Microsoft\Windows\CurrentVersion\App Management\ARPCache\

Where do they come from and why are they created? Can they be safely deleted?

(CCleaner is trying to delete them, but I don't know what they are.)

(ShowIinfoCache Reg_Binary 29 02 00 00 00 00 00 00 ff ff ff ff ff ff ff ff
00 00 00 00 00 00 00 etc....)

Daniel Petri is an MS-MVP, among his many other distinctions.

I would like to offer you two bits of advice:

1- Keep away from so-called registry cleaners, unless you equate grief
with fun.
2- Don't delete something you don't understand.
