I have done a clean install of W7 64bit Ult. I have the latest drivers. The system runs obviously without problems. But when looking in the logs I saw that at every (re-) start Windows reports a Kernel Event Tracing error: 0XC0000035 . Homegroup Log failed starting....error code 3221225525 Logging mode: 285212677.

I ran sf/scannow but there where no integrity problems.Checked with Driver Max and all drivers where OK.

Any idea what could cause this error? And any suggestions, please?
