Ccleaner 7 option /auto does no longer cleans

Since ccleqner version 7 the option /auto does

no longer clean. any suggestions ?

The command line options haven’t been supported or changed for years.

TBH I’m not surprised that they are not available with v7.
The whole development direction of CCleaner for the past several years has been towards mass-market appeal rather than being a serious tool for techies.

I’m not sure what you want anyone to suggest? If the command line switches are no longer supported in v7 then they are not supported.
Perhaps roll back to v6.39 until it gets force-updated to v7? (maybe a year maybe less).
