I am very well aware what Insider testing is about and using Insider builds.
My point was to make CCleaner aware that there is an issue SINCE Avast took over Piriform.
If a software company is not interested in input about their product, that's fine.
As stated I and others had no issues with a GSOD until the newest CCleaner update.
And other software developers ARE interested in issues that arise with their programs and Windows 10 builds.
These developers willingly work with MS to clear up a problem or find the cause.
