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.

What is Error Code 0xC004C003?

Error code 0xC004C003 has to do with activating Windows 10 after a clean install. This problem has been a frequent nuisance to users trying to update from Windows 7 or 8.1 following the invite path they got from Microsoft.

Solution

Error Causes

There are several problems that may have caused error code 0xC004C003. The most common of them are:

• The product key entered was invalid, and cannot be used to activate the new OS.
• The user followed the proper installation procedure, but the Windows update servers were too busy to handle the activation at that moment.
• The free upgrade invitation was followed but after the reinstallation, the copy of Windows 10 was still not activated.
• The user tried to perform a full clean install of Windows 10 instead of upgrading from Windows to Windows 10

Further Information and Manual Repair

A lot of solving error code 0xC004C003 has to do with the method in which the user has tried to update the system. If one decided to try and update the program before being invited to do so by the update manager, he must wait. Unfortunately, if one chooses to do it on his own and download a clean install, he was never given a product code to authenticate the process. There are two options to address error code 0xC004C003 — either restore to the previous Windows Operating System or call Microsoft (or visit their Website) and purchase a product key. The Windows update servers are very busy. There are lots of Microsoft users around the world, and the servers are doing their best to get to each and every one of the users as fast as possible, but they can only move at a certain speed. Your best bet is to sit back and wait a while. But what if you were invited, and properly downloaded Windows 10, then decided to do a clean install? It is advised that one do not try to enter Windows 7 or 8.1 serial code as this will not work. However, unlike the problem above, these users will NOT need to purchase a product key. According to Microsoft Support Staff, the installation servers are also very jammed because of the high numbers of installations going on right now. No matter what posts you may read, the key IS genuine, and it is NOT blocked, broken, or invalid. To check if Windows has been properly activated, open the Command Window. Make sure you are logged into an administrator profile; otherwise this check will not work. Type in “slmgr.vbs/ato” and click Enter and then wait. While waiting, the command will check on the status of the activation. Windows Script Host will open and show whether or not it is activated. A lot of users have reported that the activation did not work for the first few times. However they later reported after some more attempts, no issue was found in the way the operating system updated and that the activation process went smoothly. This is most likely due to the overload on the Windows Update servers, so bear with Microsoft. Users have reported that when trying to correct error code 0xC004C003, they have followed the upgrade path and then been told by Microsoft that the key was invalid and they had to purchase a new one. If the upgrade path provided by Windows 7 and Windows 8.1 is correctly followed then there is nothing to worry about Just wait a while and try it again. If there are prolonged issues, speak with a technician by visiting the Microsoft website and contacting the help center by calling the number provided. Give them all relevant information and they will be sure to help accordingly. The best solution to fix error code 0xC004C003 is to wait. In essence, the user will be waiting to reenter the same product key. According to Microsoft, and many user posts found online, it is recommended to wait a while and then try to activate again. This seemed to be an answer to most users' problems, and seem to work just fine. If the problem persists, take it to a windows repair technician to have it sorted out. If that does not work, use a powerful automated tool to fix the problem.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the reason why the calculator app is not working properly. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”. This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.

Option 1 – Try running Command Prompt with Administrator-level permissions

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again and see if you still encounter the same error.

Option 2 – Try to remove the Write Protection from the drive

As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.

Via Diskpart utility:

• Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
• Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
• After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
• Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.

Via Registry Editor:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to the following registry key:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the DWORD named “WriteProtect” and double click on it, and then set its Value Data to “0”.
• Now restart your computer and see if the problem is now fixed or not.

There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:

• Your PC’s motherboard should support both Legacy and UEFI.
• Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.

Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

• When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
• Make sure to run Command Prompt as admin and then execute this command: exe /convert
• After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
• As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
• Now save the changes made and exit as your computer will restart.
