I made an original post with my now ancient (10 year old) Satellite P105-S9722 back in 2009 & 2011 for Windows 7 64-bit drivers. I also made a post for Windows 8 & 8.1 drivers. Now that I have newer systems, I have experimented loading Windows 8, then upgrading to Windows 10 in my P105-S9722 system. Wanted to share some observations and any issues I came across. I have listed here some basic drivers you can use for your P100/P105 systems for Windows 10 and 32/64-bit to work. Many of these listed are from other users, but there may be some additional drivers many may not know about.
I can't guarantee that all of these will make your system work 100%, but hopefully this will make your upgrade just a little quicker & easier. Before using these driver, I recommend you do a fresh install of Windows 10 32 or 64-bit regardless if you are using XP, Vista, 7, 8 or 8.1 32 or 64-bit systems.

I do recommend using either a USB flash drive or DVD disk to do a fresh install of Windows 10. After installing the Operating System (OS), immediately go to Programs and Features in Control Panel. Make sure to turn on the.NET Framework 3.5 (includes.NET 2.0 and 3.0). You will need this to install some of the Toshiba utilities.
