I have some time before posted on HP Support forum HP Support forum. Strange is this, all drivers (include cameras) work properly after using CCleaner, But i have check more time, cameras stopped work after install and run CCleaner, no other applications. I dont know, maybe HP tablets work on some other principe from other win7 PCs.
Exact is after that, I run HP cameras aplication, it runing, runig few minute and show cameras pictogram with "slash" .look on picture
