One of the most useful utilities on a Windows 10 computer is the Windows File Explorer. It is undeniably one of the File Managers out there full of features on all the platforms. However, it is not without its issues and one of the most common ones most users encounter is when you are trying to open a folder or a location on File Explorer and it displays a message saying, “Working on it…” as it tries to load the content of that location or folder. This kind of issue mainly occurs to computers that run on an HDD although that doesn’t mean that it can’t happen to other computers that run an SDD. And so if the File Explorer on your Windows 10 computer keeps getting stuck on the “Working on it…” message along with a green animation bar moving very slowly while loading the contents of the folder, then it’s best if you follow the options given below to resolve this problem.

Option 1 – Try deleting the contents of the Automatic Destinations folder

• Tap the Win + R keys on your keyboard to open the Run utility.
• And then type “%AppData%MicrosoftWindowsRecentAutomaticDestinations” and hit Enter to open this location.
• From there, select all the files and tap the Shift + Delete key combination.
• After that, you will get a prompt that will ask you if you want to delete all the files permanently, just click on Yes. This will delete all the Quick Access cache.
• Now check if you can now open a folder or a location without the “Working on it…” message.

Option 2 – Try to rebuild the Search Index

• First, open the Indexing Options using the Search bar.
• Next, click on the appropriate listing, e.g. Users folder.
• After that, click on the Advanced button. This will open a mini-sized window and from there, go to the Index Settings tab.
• Then click on the “Rebuild” option under the Troubleshooting section.

Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

BSOD or Blue Screen of Death errors are one of the most common errors you can encounter on your Windows PC. One of these BSOD errors is the “ACPI_BIOS_ERROR”. If you suddenly get this error, it means that there is some problem in booting the operating system from your hard drive or Windows was not properly installed on your PC. In addition, this error could also mean that there is something wrong with the CMOS battery located in the motherboard. Unlike other BSOD errors, the workaround for this error is a bit different as these workarounds require a bit more expertise in updating the BIOS as well as setting the correct boot configuration. If you know are capable enough in troubleshooting the problem, refer to the instructions laid out below to fix the BSOD “ACPI_BIOS_ERROR”.

Option 1 – Try to remove the SSD and update the BIOS

The first thing you have to do is to check the primary storage devices on your PC. If you have just installed a new hard drive or SSD recently on your computer, then it’s most likely the cause of the BSOD error. Moreover, you should also ensure that your BIOS is up-to-date to the latest available build.

• Remove the SSD/HDD and inject a different HDD that was already preinstalled in your Windows PC.
• After that, update the BIOS to the latest available build. After updating it, insert the old SSD/HDD and then try to boot your PC again. The problem should be fixed now. If not, refer to the next given option.

Option 2 – Try to check the CMOS battery and reset the CMOS module

As mentioned earlier, the CMOS battery might also be the one that’s causing the problem. It is a physical component of the motherboard and is a memory chip that contains all the settings configuration on your computer and is also powered by a battery. So if your battery loses power, the CMOS will be reset and as a result, all the configurations will be gone as well. It is also possible that the CMOS module is not properly working and every time things are saved, they are properly written due to the battery. That’s why you have to consider changing the CMOS battery and see if it fixes the problem. In addition, you also have to make sure that you completely reset the CMOS module and then try booting your PC again.

Option 3 – Try to check the BIOS settings

If the BIOS settings are incorrect, chances are that’s the reason why you’re getting the “ACPI_BIOS_ERROR” BSOD error. Every BIOS has different settings which you can make use of to enhance your computer experience. So make sure that your BIOS is up-to-date and that the settings are in accordance with your requirement. Another thing you can try is to disable the Legacy USB and the Legacy BIOS in the BIOS settings if you are trying to install a 64 bit Windows version. Make sure that you also enable AHCI before plugging in the installation drive on your PC. Moreover, ensure that your PC is using IDE or Integrated Drive Electronics mode instead of SATA or Serial Advanced Technology Attachment. Aside from that, try to check the extracted setup if it is in NTFS format, if it is, you should extract the ISO in FAT32 and use it to install Windows.

Option 4 – Try to reset the ACPI Compliant Control Method

ACPI or Advanced Configuration and Power Interface provide an open standard that operating systems can use to detect hardware, perform power management, as well as monitor the status of your device and provide information for other processes. Chances are, there are some misconfigurations with this module on your PC that lead to believing that there is no battery present. That’s why you need to reset it and see if it fixes the BSOD error or not.

• Boot your PC into Safe Mode.
• Tap the Win + R keys to open the Run dialog box.
• Type in “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After opening the Device Manager, go to the “Batteries” section and click it to expand it and then right-click on the “Microsoft ACPI-Complaint Control Method Battery” option and click on Uninstall.
• After you disable the module, click on any empty space and then click the “Scan for hardware changes” option.
• Then check if you can now boot your PC normally and without the BSOD error.

As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:

“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”

This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
• After opening the Services Manager, look for the Windows Modules Installer Worker Service.
• Once you found it, check its status and make sure that its Startup type is set to Manual.
• Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.

• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

One of the most useful and efficient command-line disk management tools is the DISKPART utility. It can be used to manage, delete or create new hard drive partitions. However, despite its efficiency, there are still times it could face some errors like the “No usable free extent could be found”. You can encounter this error when you create a partition. This error could be due to insufficient disk space which is why it is not able to carry out the operation. It is also possible that the disk is not recognized by the system. And since there are only four recognized primary partitions, when you try creating a fifth one, you will get this error. In addition, this error could also occur if the disk has been partitioned using the MBR disk partitioning format. To fix the “No usable free extent could be found” error, here are some suggestions you can follow.

Option 1 – Free up disk space using Storage Sense

The error could be caused by insufficient disk space in your computer and so you need to free up disk space using Storage Sense to fix the problem.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clear Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Note: You can also run the Disk Cleanup tool to free up disk space.

Option 2 – Try to run DISKPART in Command Prompt with administrator permissions

The next thing you can do to resolve the error is to run the DISKPART utility with admin privileges.

• 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. Note that you also have to specify different size & offset values for the partitioning and then see if you still encounter the same error.

Option 3 – Try to execute the DISKPART clean command

The next thing you can try is to execute the clean command in DISKPART to fix any issues in the disk.

• Open Command Prompt with admin privileges.
• Then execute this command: diskpart
• The command you entered will initiate the DISKPART utility. Now execute this second command to view all the disk connects or all the partitions on those disks formed: list disk
• After that, you need to select one command depending on the list command you executed and then execute this third command: select disk #
• The third command you just executed will select the disk or partition you want to select. Now execute this fourth command: clean
• The command you entered will remove all the volumes or partitions formatting the disk in focus.
• Once it’s done, try to carry out the DISKPART operation you were trying to execute.

Option 4 – Try to update the USB drivers

Outdated USB drivers can also be the reason why you’re getting the error. Thus, you must update them from time to time. You can install the latest version of the USB driver for your system. But you need to check the manufacturer’s website or guidelines to update the driver according to your system. If it happens that the drivers might not be compatible with the version of the system your laptop is using which is unlikely, you can run the driver software in Compatibility Mode in that kind of situation. To update your USB drivers, follow these steps:

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, look for the USB Serial Bus controllers from the list of device drivers displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.

Option 5 – Run the Hardware and Devices troubleshooter or the USB troubleshooter

You can find the Hardware and Devices troubleshooter under the Troubleshooters section of the Windows Settings panel on your Windows 10 PC. You can use this troubleshooter to fix common hardware and external device-related issues without exerting too much effort. If you don’t know where to find it, follow these steps:

• Tap the Win + I keys to open the Windows Settings.
• Next, navigate to Update & Security > Troubleshoot.
• You should see the option for Hardware and Devices on your right-hand side where you can also find the “Rub the troubleshooter” button – click on it to get started.
• Follow the next on-screen instructions to fix the basic issues of common hardware and external device.

Note: If you want to, you can also use the USB Troubleshooter to fix the problem just go back to the Troubleshoot page where you can find it.

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.
