If you are using the Camera app on your Windows 10 computer but encountered an error code 0xa00f429f with an error message that says, “Can’t start your camera”, read on as this post will guide you in fixing this problem. This kind of error in the Camera app could be due to a recent update gone wrong or it could also be due to a corrupted driver. If you are certain that the camera is connected and is properly installed, you can try to check for updated drivers. The error code signifies that the drivers have to be updated. However, that isn’t always the case sometimes as the problem could also have something to do with corruption in the driver. The effective ways to troubleshoot this problem would be trying to reinstall or reset the Windows Camera app, or update, rollback or uninstall some device drivers as well as use the Registry Editor. Before you proceed with the instructions provided below, make sure that you have admin privileges and don’t forget to create a System Restore point.

Option 1 – Try to reset or reinstall the Windows Camera app

As pointed out earlier, you can also reset the Camera app to fix the error. To do so, follow the steps below.

• The first thing you have to do is go to the My Pictures folder under the C: drive of the File Explorer and then delete the Camera Roll folder.
• Once you’re done, right-click on an empty area on your screen and create a new folder and name it “Camera Roll”.
• Then from the Start menu open the Settings app and select System.
• From there, navigate to the Apps and features section.
• Now go to Camera and click on the Advanced Options and click the Reset button.

Option 2 – Try to reinstall the Camera app

If resetting the Camera app didn’t help, you might want to reinstall it by following these steps:

• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option from the menu to open Windows PowerShell as admin.
• Next, type this command to uninstall the Camera app: Get-AppxPackage *camera* | Remove-AppxPackage
• Once done, exit the Windows PowerShell and restart your computer and then try to install the latest version of the Camera app from Microsoft Store.

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the error code 0xa00f429f in the Camera app is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, look for the device drivers which have a yellow exclamation mark.
• Then right-click on each one of them. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
• Next, follow the screen option to update or uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall them.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try to use the Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftWindows Media FoundationPlatform
• From there, right-click on any empty space on the right side part of the window and select New > DWORD (32-bit) Value.
• Then name it as “EnableFrameServerMode” and double click on it.
• Now set its value data to “0” and its base value as Hexadecimal and then click on OK.
• After that, restart your computer and see if it helped in fixing the problem or not.

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”

As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.

• First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
• If a User Account or UAC prompt appears, just click on Yes to proceed.
• Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
  • UsoClient StartScan – use this command to start checking for updates.
  • UsoClient StartDownload – use this command to start downloading updates.
  • UsoClient StartInstall – use this command to start installing the downloaded updates.
  • UsoClient RestartDevice – use this command to restart your computer after you install.
  • UsoClient ScanInstallWait – use this command to check, download and install updates.

Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:

• wuauclt /detectnow – use this command to start checking for updates.
• wuauclt /updatenow – use this command to start installing the updates detected.
• wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
  • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
  • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
  • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

As you know, USB is now being widely used in all devices with USB A as the leading type with most devices based on it. Peripheral devices such as Pen Drives, External Hard disks, and many more also use a USB port. On the other hand, USB C is also coming up to be the next big standard in the computing world because of its high transfer speeds, wider compatibility as well as support for external Graphics Processing Units. However, just recently, USB 3.0 ports have been reported to cause the following error to pop up on Windows 10 computers every time a USB device is plugged in.

“Not enough USB controller resources. The controller does not have enough resources for this device.”

To fix this error, here are some guidelines you can check out. Make sure to follow them carefully.

Option 1 – Try to use a lower generation USB port

The first thing you can do is to try using a lower generation USB port as this issue mostly occurs when a device is connected to a USB 3,0 port. This means that you have to plug in your device to a USB 2.0 port and then see if it fixes the error or not. You can easily decipher a USB 3.0 port from a USB 2.0 port as the former is in blue.

Option 2 – Try to use a dock

You could also try to use a dock to resolve the error. Note that when too much power on laptops and notebooks are drawn from the USB ports and as a USB 3.0 port draws more power compared to a USB 2.0 port. Thus, if you plug in your USB storage device into a USB 2.0 port with the help of a dock, it should fix the problem.

Option 3 – Try disabling the xHCI Mode option in the BIOS

• First, boot your computer into the BIOS.
• Once your computer has booted, go to the Advanced tab.
• Next, make sure that the entry for “xHCI Pre-boot mode” is set to Disabled under the USB Configuration section.
• Now save the changes you’ve made and then restart your computer to Windows 10 and see if the error is now fixed.

Option 4 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right click on each one of the USB drivers, especially the Generic USB Hub driver, and then select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 5 – Run the Hardware and Devices Troubleshooter

You could also run the Hardware and device Troubleshooter to try and fix the “Not enough USB controller resources” error.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1. This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002. Now locate the following registry key: HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open. Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys: HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation. This will resolve the stop C000021A error.
