[Solved] Options to prevent hibernating and rebooting if JDownloader has active downloads

Could you add an option into JDownloader that will prevent the computer from hibernating and another option that will prevent the computer from rebooting? I think it would be better if hibernation and rebooting would only be prevented when there are active downloads running in JDownloader, instead of whenever JDownloader is running on a computer.
I know that at least preventing hibernation should be possible since µTorrent does that. Preventing rebooting might have security complications though (and maybe trigger false positives from some antivirus softwares?), so do what you think is best about that suggestion.

The reason for these suggestions is that I'm tired of hibernation and automatic rebooting after Windows Update messing up my downloads from shitty filehosts so that I have to restart them.

Under Windows/Mac Settings-Enable the AntiStandby Extension. During Downloads JDownloader will then prevent Standby

Ah, I must have missed that. Thanks!

Jiaz does it also prevent Windows from restarting because of updates?
Well I suppose it does as I never had a problem with running JD and Windows (7) updates waiting for a restart.

For this specific case:
There is the possibility to permanently disable the unnerving updates-restart prompt which I'm using myself.
Simply make a .bat out of this and run it:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
"NoAutoRebootWithLoggedOnUsers"=dword:00000001

Nope it does not Prevent Restarts

I have no idea if windows will force restarts after some time (after asking the user) but I suppose as long as a programm is running (antistandby should be enough) it won't just shut down...
