Microsoft deemed it was time for my PC to be upgraded to Windows 10 Creators Fall Edition. This is my experience with an Nvidia graphics card:

1) Whole thing took about an hour (update was already downloaded, and I had previously delayed installation)

2) Make sure you put the SETI project into suspend mode before you start - this stops BOINC Mgr restarting work

3) The Fall update replaces the Nvidia driver with a Microsft version, this will result in the GPU tasks showing GPU missing in BOINC manager (this is why suspending the SETI project was useful)

5) Install Nvidia driver from Nvida web site ( I did a clean install)

6) Reboot PC

7) Start BOINC - SETI GPU work units now OK, resume SETI and crunching restarts just fine.

8) The update had reset the automatic driver install back to yes.

MS updates are ignoring this setting on 7 and 8.x also. Sorry to say but the setting is useless. The best thing about 7 and 8.x is that I can hide those updates and not apply them.

Replaced Win10 - too many problems with it on a 1 year old HP desktop. Hardware always passed diagnostics. Had a suspicion that initial Win 10 was corrupted and it got worse with the upgrade. Rather than debug another PC with Win 10, I installed LINUX MINT 18.3. Machine runs like a champ. Just have to figure out how to get BOINC to use the builtin CPU AMD GPU.
