Can I delete CbsPersist logs safely, your opinion please

[Beehelp]

Hi,
On my laptop (Windows 7 64bit) I have discovered I have in the folder "C:\Windows\Logs\CBS" the following

CBS.log 26/12/15 Text Document 2105 KB
CbsPersist_20110413024632.cab 18/02/11 WinRAR Archive 946KB
DeepClean.log 15/11/15 Text Document 616KB
FilterList.log 07/07/15 Text Document 1KB

It is the ones below I'm interested in deleting as in total they are taking up 18.1GB

Also 21 CbsPersist_xxxxxxxxxxxxxx.log (where xxx is the date and time) Dates ranging from 07/07/15 to 18/12/15 Text Document Size From 204709KB (199MB) to 5904612KB (5.63GB)

I have read different comments from a few other sites where they often contradict anther.

Any opinions on what I should delete would be grateful. Thank you in advance

The CbsPersist logs are really only useful to diagnose problems and issues that are related to Windows Updates / Com Store.
It would be safe to delete all, but should probably keep the last one, as that's usually the latest.
