Since my Win7 system received an updated version of CCleaner, I no longer see any issues found when I run the Registry Cleaner. That's a big change from the past when there were always multiple issues found. Colleagues with Win7 systems report the same. Is there an issue here? Haven't seen any internet chatter on the subject.
What build number of CCleaner?
V 5.01.5075 (64-bit). CCleaner web site reported I have the latest version.
Windows 7 Home Premium 64-bit SP1, all available updates installed as of this morning (1/26/2015).
Trend Micro Maximum Security installed.
Just installed V 5.02.5101 (64-bit), same results on Registry scan- no issues detected.
Do the other machines also have Trend Micro on?
Unknown. Will ask.
One of the others responded. He's using Avast and Webroot, so the anti-virus package seems less likely to be involved in this.
Are the other machines connected to yours in anyway? Same network etc?
We are all members of the same internet forum. Other than that, there is no connection between the machines, different parts of the country, different networks.
Doing as you say, CCleaner does not report an issue in Registry Cleaner with the file I created with a bogus extension.
Should you decide to go back to an older CCleaner version where the registry cleaner worked for you they are here:
