Windows 7: Hardware Profiles

The point with HW profiles is that certain HW does not play well with some reasonable uses of a computer. For instance, the way some Dell laptops implement ACPI battery control and WLAN breaks real-time audio recording and streaming. For such a laptop to be useful for real-time audio recording, these HWs must be disabled. In XP this is simply implemented with HW profiles invoked when the computer is started up for the audio recording task. When wanting to surf, the computer is retstarted with a HW profile that enables the WLAN.

That HW profiles have been removed is unfortunate.

PS These types of tools illustrate what I'm talking about DPC Latency Checker

I was using different hardware profiles for different locations. I'd use the docked profile with features such as wireless and bluetooth turned off when I docked my laptop at work where I do have a dock. On my undocked profile, I'd turn off ethernet network adapter and turn on wireless adapter which I use when I'm working from any location thats not my office.

Now, with Win7, I dont see a way to achieve the same result.

If hardware profiles don't exist in Windows 7, how else can I have the same IP address for the machine as I repeadedly dock/undock it? In XP, the wired NIC and the wireless NIC had the same fixed IP address but existed in separate HW profiles so there was no conflict. I need the same IP address for port forwarding and for accessing servers from other systems on the LAN.

I hate to have to install extra software to do something basic that XP has been doing for almost a decade but bridgechecker seems to work around the Windows 7 limitation. Have not tried it but it sounds promising for anyone reading this thread.

BridgeChecker v1.2 Available for Download at WLAN Book.com

Ubuntu with Win 7 VM
 
 

With Win XP hardware profiles there were a number of things that i was able to do that i cannot do now in Win 7. Here is my current setup. My primary OS is Ubuntu and i have both VMWare and VirtualBox installed. My WinXP used to run inside either VMWare or VirtualBox depending on whatever i wanted to run it with. I had two HP's in WinXP, one for VMWare and one for VirtualBox and this was NECESSARY since the virtualized hardware exposed by both is quite different. I could happily use the same instance of WinXP from both the softwares. Now i i cannot do that with Win 7 since every time i switch from VMWare to VirtualBox or vice versa, Win 7 thinks this a totally different computer and goes thru a whole bunch of reconfiguration.

I understand that my use case is a very corner case and most people would not be doing that but the point here is that having HP allows you to do these things are now not possible.

Could you guys clarify a few things. I have 2 PCI satellite cards installed in Win 7, and there drivers conflict. Is there a way, I can disable one selectively at system startup, similar to HP feature in XP? Another thing is, when selecting a certain HP in XP with one card disabled, would it mean to shut down voltage to its PCI port? Or it will remain fully powered, but merely without drivers loaded? What's the point to have it powered then?

Hi All,

I just found something interesting related to Hardware Profiles in another SevenForums thread:

https://www.sevenforums.com/windows-u...tml#post661022

The Microsoft copy refers to "every hardware profile that is listed", which would seem to indicate that there could be more than one. Does anyone have any additional information on this?

Either way, I have a crying need for Hardware Profiles or the equivalent in Windows 7. I'm using a dedicated computer for recording digital audio, and I don't need the vast majority of services that run in the background when I'm recording. I do need them, however, when I'm doing routine tasks, such as restore/backup procedures, activating software, etc. Any ideas as to how I could have two Hardware Profiles, or the equivalent, would be greatly appreciated.

Thanks,
Sam

Same thing here. What I do (on my laptop, not necessary on the desktop) is I use devcon.exe with a script to disable stuff before starting the DAW, and then enable that stuff afterwards. It works, but getting your hands on the devcon.exe utility (it's from MS) is not entirely simple, unless you DL the entire driver SDK. There is a post somewhere on the web about how to use Universal Extractor to get only devcon.exe without having to install the entire 700 MB (or something) driver SDK. Sorry, I cannot find it right away just now, just google.

EDIT: Found it http://social.answers.microsoft.com/...4-fc4ff0ea6ee8

Difficult to believe MS removed such a useful feature... (well, maybe not so difficult).

I can't use Win-7 on my Laptop as one of the HW setup's is for mobile recording, easy to disable wireless, ACPI Battery Control and a couple of other devices that interfere with consistent real-time operation. I've used it this way for a year now, can record 8-12 tracks of uninterrupted audio for 2 or more hours if required.

Oh well, XP is lighter on resources anyway.

Thanks very much! This is the first promising lead I've had in months of searching. I'm reticent to admit, however, that some of this solution is over my head. I was able to successfully extract and run devcon.exe from a command prompt, and here's what happened:

Please let me know if I'm missing something, doing something wrong, etc. If you need more info to determine it, just let me know.

Thanks,
