We have installed Windows 10 Technical Preview on a Toshiba Satellite L505. The version was Build 10041. The automatic update for the Realtek Semiconductor Corp. Driver Realtek High Definition Audio failed multiple times. The update to Build 10074 failed multiple times after the Realtek update failed.

After waiting for the issue to resolve itself, we downloaded the Build 10074 install, burned it on a DVD, and installed it. The install flowed smoothly.

We have not been able to try Edge the new browser to replace Internet Explorer.

The Satellite L505 laptop has a 64-bit processor, Intel Core 2 Duo CPU @ 2.10 GHz, with 4 GB memory. This machine originally had 64-Bit Windows 7 installed.
