After about 2 week I connected the Windows 10 TP 9901 HDD back in my Laptop and booted from it. Mainly I would testing RAdmin with it and here the first problem: RAdmin Server installing on 9901 wasn't a problem. Accessing from Desktop via Internet (because of an different Internet connection) in full Remote, means all works from Desktop as it does on Laptop, the Cursor of the Mouse disappears on Laptop, Only if I open an other window via Remote on the Server (Laptop) the Mouse Cursor could be seen just in that windows but outside. That happens as long as I'm connected to the Server (Laptop) in full remote power. Regarding that problem I opened an Ticket at RAdmin Support already. Next is: from time to time an Diagnostic Window open on Laptop without to show any indication what it does etc. Than Problem with HP Mobile Mouse: I use an HP Mobile Mouse, which is working with WiFi but isn't a wireless Mouse! I also had a bit problems with it on Windows 8.1 pro but could solve by editing the driver. That didn't works in 9901 or any other Windows 10TP till now. The procedure to connect is that an apps from HP need to be used and after install the mouse need to be paired with the Laptop. That Paring Process runs endless and I didn't got any info from HP Service, nither by HP Thailand nor via HP Support on the Internet. Not any answer from later!! Maybe someone has an Idea what the Diagnostic window all time is doing? Thanks.
