I hated it when the previous versions of Win 10 would restart in the wee hours of the morning and not give a warning before. Prime95 and/or mfaktc would just sit until I got up in the morning and would notice they were not running.

1903 will give me a warning when it wants to restart outside of "off-line" hours. This machine has no "off-line" hours. It is always running something. If would be nice if I could configure it to not restart anytime without me allowing it to do so.

I kind of accomplished that, by setting the "active hours" to coincide with when I sleep. That way I am guaranteed of no reboots overnight.

Windows 10 Education and Pro gives you the option of delaying restarts. Also, you can disable automatic windows update restart by editing it services (services.msc).

Alternatively, you can automatically have your applications start on windows startup. Make a shortcut of your .exe or make a .bat to start it, then drag those to C:\Users\[your user name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.

Yes it is annoying, that's how I got around it. I'm sure someone already filed a suit against msft for forcing people to restart.

I think what you wrote is start-up of selected applications when the user logs in afterward, not at system boot.

Oops epic failed again. I think the correct one is

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\

Thank you. Both for the update and your preceding post. Convergence is good. Participation is essential.

Here works, for now. If people would use it, I will create a discussion thread dedicated to gpuowl tune. I suggest including most if not all the elements of https://www.mersenneforum.org/showpo...postcount=1553
Most essential are the gpu model, gpuowl version & commit, optimal -use settings, and expected timing for a stated clock rate and stated fft size, preferably the first-test current wavefront which is 5M now, and computation type. Right now there's PRP and P-1 stage 1 or 2. Possibly later LL will return. OS is also recommended.

To make this easy we could create a blank form post, a sort of skeleton to which the individual benchmark and tune data could be added and reposted.
I may toss a draft form together. They're likely to vary, as the available -use options vary with the commit number.

The folder:

is for programs that should start only when that specific user logs in, while the folder:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\

is for programs that should start for all users logging in

So, the second is also not at system startup.

What we really need is the equivalent of --perftest from mfakto to gpuowl - while I don't mind manually doing it takes a decent amount of time and others may not be inclined to do something like this... Plus, I'm sure retests will be necessary as things are changed or added in time.
