I've looked at xperf traces of several users and here the function ntoskrnl.exe!SmKmStoreHelperWorker of the Kernel starts to allocate memory. (Click image to enlarge) I discovered this on sysinternals. I've asked Microsoft about it and the answer is that this is by design. It is related to System Memory compression. In the announcement of Windows 10 ...

If your headphones were USB headphones, they may not require drivers as there is a standard manufacturers can follow so the devices they create do not need additional drivers. This is the same way most mice and keyboards "just work". If your headphones just use a normal jack, the machine's sound card has a set of controllers that are doing the processing ...

HDMI and DisplayPort are capable of transmitting audio as well as video. So, to Windows, it looks like an additional soundcard appears on your system, for which a driver is needed. So if you connect a monitor on the other end of your HDMI or DisplayPort and it can play sound, you can send sound to that monitor by selecting "Intel Display Audio" or ...

Most manufacturers let you download drivers from their website by entering your computer's model number or serial number. Here are links for a few of the most popular laptop manufacturers. You can usually find manufacturers' driver sites by googling manufacturer name drivers. Toshiba Drivers Dell Drivers HP Drivers ASUS Drivers Acer Drivers Lenovo/IBM ...

This is what you need, sudo kextunload /System/Library/Extensions/AppleHDA.kext sudo kextload /System/Library/Extensions/AppleHDA.kext But if you want to kill your coreaudio as well, ps aux | grep 'coreaudio[d]' | awk '{print $2}' | xargs sudo kill use with caution. The grep target is written this way specifically to exclude grepping the grep ...

This isnt an unbreakable rule. The main reason to install drivers first is that the device manufacturer knows the drivers did not ship with Windows XP (or whichever OS). You can certainly plug the device in and the world will not implode in a cataclysm of fire. Typically, Windows will complain that it doesnt know what the device is and prompts you to ...

Simple answer, they don't require 500 MB, or 50 MB, or even 5 MB of drivers. A PCL (what most inkjets speak) driver is in the hundreds of KB. Likewise, a postscript driver is equally tiny. In Windows you can, in fact, install and use most printers using a built-in driver, even if it's not the "right" driver. You would be astounded at how many ...

Finally cracked it! It's to do with the printer name in the driver's inf file. When I installed Windows 7 it automatically installed the MP600 driver but it called it "Canon Inkjet MP600 Printer". NOTE Inkjet. When you unzip the Canon driver and look in its driver folder the printer inf file is called MP600PR.inf. Edit this file with Notepad and you will ...

The generic drivers are often provided by the manufacturers themselves, but they are specifically designed to get the system working at all, not necessarily working well. Further, depending on the component, they may outdated and can not only run slower than with a newer driver, but also have bugs that may have since been fixed. Plus, you may think that your ...

Drivers are software interfaces between the operating system and the device. They allow indirect but standardised communication. Without it, developers would have to talk to the device directly and write code for every imaginable piece of hardware. Headphones have no need for such an interface, because there is no communication with the operating system ...

DevManView is another way to do this - and it's a lot easier to acquire than devcon.exe, but still free. I use the following command in a batch file to use disable/enable a device on my wife's laptop when we need it: devmanview.exe /disable_enable "SDA Standard Compliant SD Host Controller" You can also create a regular shortcut, edit its properties and ...

I had the same problem as well. The issue seems to be that the Bootcamp software is looking for the correct Realtek drivers, but can't find them so it just hangs. To fix it, manually install the drivers from Realtek while the Bootcamp setup is running. Then, go to Task Manager, find the Setup process, right click and press Go to details. Then find the ...

Maybe because plugging it in first might result in some default driver getting installed which lacks the options (bloat?) the recommended driver package offers. This is not only likely to confuse a normal user, it is then going to be extra confusing/difficult to teach him/her how to update the driver to the recommended one (resulting in lots of unnecessary ...

You need USB 3.0 drivers to read installation media. Windows 7 is fine with AHCI.

The BIOS in a PC was meant to fufill a similar function as the BIOS in an 8-bit CP/M system, popular before the PC took over in the mid-80's. The BIOS was intended to contain a minimal bootloader and hardware-dependent low-level routines to do input and output to a few devices (screen, disk, tape, COM port). Knowledge to do this was built into the ROM - no ...

If you have Windows XP running, first step is to go into System->Device Manager in the Control Panel and write down the names of everything with a yellow exclamation point. Each of those devices are the things that need drivers. Sometimes the names are very descriptive: "Realtek 8139 Ethernet". Some are less descriptive: "Ethernet adapter", "AC97 Sound ...

The following thread has many explanations and workarounds : Missing sound recording option "Stereo Mix" / "Record What you hear" / "Waveout mix". One of them is : Since Microsoft intentionally removes the Stereo Mix / Waveout Mix option from its drivers, you need to try to download the latest version of the sound card driver and install it. If ...

Yes - those are just the files extracted from the download into a temporary location. The actual Nvidia program files are located as default: C:\Program Files\ etc. The NVIDIA folder can indeed be deleted. It can sometimes be a handy feature to have giving you access to all the seperate installers and driver components of the download for a more granular ...

Take a look at this tutorial which explains how to use the Microsoft Management Console (MMC), to remove unwanted printer driver packages. If that does not work for you, try using the printui.exe tool. In an admin elevated command prompt type printui /s /t2, be sure to remove the driver AND the package. Here's how to do it, step-by-step: Open a command ...

Looks like there was no easy way. In Windows 10 preview they force automatic updates on you, and since build 10049 there's no way to restore the "old" Windows Update applet in Control Panel. But I managed to do with with a set of PowerShell tools called Windows Update PowerShell Module. After you install the PowerShell tools, list all the available updates ...

The problem is a bit mysterious until you realize what's happening behind the scenes during a windows install. And, there is a workaround to allow you to use USB 3.0. One workaround is easier in the moment, the other requires a bit of work to setup, but will be easiest for future installs. Introduction: What exactly is the problem Here is a lengthy but ...

If you’re familiar with Windows XP Service Pack slipstreaming, this is pretty similar. I’m using Windows XP Professional for this example. It should be similar with Vista etc. Make ISO image from your Windows 7 DVD with your favorite software. I used CDBurnerXP. Save install.wim somewhere on your hard drive from that ISO image or straight from DVD. ...

Firmware is the software that runs on the device. A driver is the software that tells your operating system how to communicate with the device. Not all devices have firmware--only devices with some level of intelligence. I'm not exactly sure what you mean... generally speaking, firmware has nothing to do with "booting"... I think maybe what you're asking ...

I think it's a relic of history. On the PC side printers have evolved from the character-by-character bunch (so, you send ASCII to them, they type it out as though they were a typewriter) through the Epson FX80 era (which is ASCII + control codes) into pixels. I think the level of competition and the fact that they were building up from devices that didn't ...

Every device you own uses a driver to communicate with the OS. In most modern operating systems, the default built-in drivers are enough to cover a myriad of devices, such as keyboards, mice and speakers. But once in a while, a device comes along that the OS engineers haven't designed for. I.e., my Fitbit - a USB/wireless pedometer. In that case, you need ...
