I click the Windows 7 orb, type Powershell, start one of the (4) applications found, type the command and hit enter - Powershell responded that the term 'curl.exe' is not recognized as the name of a valid function.
Looks like curl.exe is only included in Windows 10.
Try this instead:
Invoke-WebRequest -UseBasicParsing -Method Post http://127.0.0.1:8089/hls/hwaccel
Is there a way to test this if your server is running on an nVidia Shield?
More logs sent. Still no option for hardware transcoding, even after updating Intel drivers. It's strange that I can get hardware transcoding with QSV using Handbrake, but not with CDVR. Any ideas?
By any chance did you install it as a service ? I have seen this problem when it is Installed as a background service.
No, I'm fairly sure that it's just installed to run in the system tray. I don't see Channels DVR service in the list. It would be great to have this feature working as the processor currently spikes to 100% with just one remote device streaming. It's an older processor, but Quicksync capable and running at 4.2 ghz, not to mention one of CDVR's greatest features is it's remote streaming ability.
This Win 7 system hasn't had a Windows Update in 3 or 4 years, and it would be best to keep it that way for various reasons, but if there is something that it's missing specifically, I could certainly install it.
Any additional ideas, Aman?
Here's the HWE log after running the command that Aman mentioned:

Does you have Plex installed by any chance? Would be useful to know if it can hardware transcode or not.
I don't have Plex installed. I'm not a Plex user. How can I help otherwise?
I have an idea for one thing I can try which may or may not help.
Similar issue was reported in QuickSync not working on Win 7 x64 and we were not able to figure out the root cause. Others seem to be able to run Win 7 and h/w transcode so it's unclear what the difference in these cases is...
Have you ever seen evidence of a Win 7 system can h/w transcode with Channels DVR?
I do appreciate you looking at this, and I certainly understand if the complexity is beyond what can be reasonably solved.
Yes we have a number of users still on Win7 that are able to transcode. Given that the EOL is less than a month away I'm not sure how much more effort we're going to put into Win7 specific issues, but I can try a simple fix later this week which could help.
Well, I respect that. I believe Win 7 is a solid option for many years to come, but I do understand your position.
Are there any other users that are successfully h/w encoding without a discrete vid card in Win 7 that would care to chime in?
Does anyone know if Win 7 is actually offering some form of paid support significantly beyond one month from now? I don't know if Channels DVR is willing to support it, but just wondering.
Not that I know of.
Microsoft ended mainstream support for Windows 7 in January 2015, with extended support running till 14 January 2020 .
Microsoft won't provide technical support, software updates, security updates, and fixes after January 14, 2020
Starting on January 15, 2020, a full-screen notification will appear that describes the risk of continuing to use Windows 7 Service Pack 1 after it reaches end of support on January 14, 2020. The notification will remain on the screen until you interact with it.
Well, I guess there must not be any extended paid support of Win 7. In any event, if Channels DVR chooses not to continue support for Win 7, that's certainly your prerogitive.
