If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL
• KERNEL DATA INPAGE
• SYSTEM SERVICE EXCEPTION

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named ACPI.sys and rename it to ACPI.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the 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.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
• Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
• After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC 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 with good system files. 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 PC.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like ACPI.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Run System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

What is Regsvr32 Error? - What Is It?

Regsvr32 is basically a command-line utility.

This command is used to register and unregister OLE controls for example the digital link library files and ActiveX controls in the Windows Registry. This command appears as the Regsvr32.exe file and is installed in the Microsoft Windows system file in the %systemroot%System32 folder.

The Regsvr32 command loads the library and tries to call the DllRegister Server and DllUnregister Server. In other words, it helps to register COM-based digital link library files to run different programs on your PC.

However, when the Regsvr32.exe file gets corrupt, you get the Regsvr32 to troubleshoot the error message on your computer screen. It can be displayed in various ways including the following:

“To register a module, you must provide a binary name.”

Error Causes

Generally, Regsvr32.exe becomes corrupt because either the load library, DllRegister Server or DllUnregister Server function fails. This indicates that the dll specified path was missing, incorrect, or couldn’t be found.

Here’s how the error messages are often displayed while registering a dll using Regsvr32.exe:

• “The command-flag "%1" is not valid. Please review the command usage and try again.”

If this error message is displayed, it typically means that you entered an invalid combination of command-line arguments or switches when calling upon the Regsvr32.exe application.

• “To register a module, you must provide a binary name.”

The cause of this error message is that you called the Regsvr32.exe function with no modules to register located in the command line arguments.

• “The module "%1" failed to load.nn Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.nn%2.”

This Regsvr32 error message indicates that Windows had problems with loading the modules that you have identified in the command line.

Further Information and Manual Repair

Here are 2 recommended solutions to fix the Regsvr32 error on your PC:

1. Re-run the command

   You must re-run the Regsvr32 command from an elevated command prompt. For this, go to the start menu and type Command Prompt in the search box.

   Now right-click the Command Prompt and click the option that says Run as Administrator to run the command on your PC. If it prompts you to enter an administrator password, type the password and then click Allow to run the command.

2. Register a 32-bit Dll using a 32-bit version of Regsvr32 on a 64-bit version of Windows

   This may sound tricky but it is even simpler than the first solution discussed above. To register a 32-bit DLL using a 32-bit version of Regsvr32 on a 64-bit version of Windows, open an elevated command prompt.

   After it’s opened, if you see the 32-bit DLL is located in the following path: %systemroot%System32 folder, move it to %systemroot%SysWoW64 folder. Once you change paths, run this command: %systemroot%SysWoW64regsvr32 <full path of the DLL>

Try following these 2 recommended solutions to immediately fix and repair this error on your computer.

The solutions should eliminate the occurrence of error messages such as “To register a module, you must provide a binary name.” It is so easy and effective and you can do it on your own without calling over a professional.

If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message. In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below. Step 1: Tap the Win + R keys to open the Run utility. Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt. Step 3: After opening Command Prompt, execute the following command:

rd \.file-folder-path /S /Q

Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:

rd \.C:Users<username>DesktopCON /S /Q

However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.

FSUTIL reparsepoint delete C:Users<username>DesktopFileName DEL C:Users<username>DesktopFileName

In this post, you will be guided on what to do if the Recent Items are no longer visible in the Taskbar icons in Windows 10. This can be quite inconvenient especially if you work simultaneously on many files and documents together and would require you to visit them regularly to incorporate changes. Thus, if you find that the Recent items are not visible in the Windows Taskbar, read on. In order for the Recent Items to appear on the taskbar icons in Windows 10 again, there are four potential fixes you can check out. You can try to show the recently opened items via Settings or clear the cache of the recent items. You could also make some changes in the Windows Registry or use the Group Policy Editor. But before you proceed with these potential fixes, it’s best if you create a System Restore Point first just in case something goes wrong after you made changes in the system. The System Restore Point allows you to undo these changes and bring back the previous state of your computer. Thus, you need to create one and then carefully follow the given options below.

Option 1 – Show the recently opened items via Settings

The first thing you can do to fix the problem is to show the recently opened items through the Settings app.

• Open the Settings app and select Personalization.
• From there, select the Start option and scroll down until you see the “Show recently opened items in Jump Lists on Start or the taskbar” option.
• Make sure that its toggle button is turned on.

Option 2 – Try to clear the Recent Items cache

• Tap the Win + E keys to open File Explorer.
• Next, copy and paste this link on the address bar: %AppData%Microsoftwindowsrecentautomaticdestinations
• Once you’re in the given location, you should see multiple files. Now select all these files and completely delete them.

Note: These files are automatically recreated when you interact with the system like performing tasks such as opening apps or accessing files.

• After that, go to this next location: %AppData%Microsoftwindowsrecentcustomdestinations
• Once there, delete all of its files and restart your computer. This should resolve the problem.

Option 3 – Try making changes via Registry Editor

The next thing you can do to fix the problem is to apply some tweaks in the Registry by following these steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry sub-path: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersion
• From there, select the Policies Explorer folder located in the left pane.
• Then move to the right pane and look for the “NoRecentDocsHistory” entry and right-click on it.
• Now delete this entry.

Note: This entry is the one that stores the Group Policy setting for “Do not keep the history of recently opened documents. The Group Policy adds this entry to the registry with a value of 1 if you enable the “Do not keep the history of recently opened documents” policy. On the other hand, if you disable the policy by setting it to “Not configured” or deleting it, the Group Policy will delete the entry from the registry, and the system will act as though the value is 0 – for instance, it keeps the history of the recently opened files in your computer.

Option 4 – Try to use the Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to launch the Group Policy Editor.
• Next, navigate to User Configuration > Administrative Templates > Start Menu and Taskbar.
• Afterward, double click on the “Do not keep a history of recently opened documents” policy located on the right panel. This is the policy that lets you enable or disable recent items and frequent places.
• Now to enable the recent items, as well as the frequent places, feature, click on the “Disabled” or the “Not Configured” option.
• Once you’re done, close the Group Policy Editor and restart your PC.

Note: If you choose to enable this setting, the system and Windows programs will not create shortcuts to documents opened while the setting is in effect. Aside from that, they also stay but won’t display the existing document shortcuts and the system will empty the Recent Items menu on the Start menu and the Windows programs won’t also display shortcuts in the Start Menu. In addition, the Taskbar won’t also show the recently opened or frequently used folders, files, or websites.

If you are trying to install or upgrade your Windows 10 computer but suddenly encountered an error message saying, “Windows Could not configure one or more system components”, read on as this post will show you how you can fix the problem. You are not alone in experiencing this problem as other users also reported having the same scenario. Some of them reported getting the following error message:

“Windows could not configure one or more system components. To install Windows restart the computer with error code 0xc1900101-0x30018.”

When you check on the Windows 10 rollback log, you will see a part with the “iisetup.exe” that’s related to the abort. Usually, the upgrade process completes over 50% and gets stuck and then rolls back later on and generates the error logs. This kind of error, in most cases, appears during the upgrade of Windows 10 and is related to the Internet Information Services or IIS in Windows 10. For some unknown reason, it restricts the installation or the upgrade which causes the error to appear. To fix the “Windows could not configure one or more system components” error, you can try to remove the IIS from the Windows Features or rename the “inetsrv” folder. You could also move all the folders related to IIS to another drive. For more details, refer to the options provided below.

Option 1 – Try to remove the IIS from Windows Features

The IIS is installed from the Windows Features and you can find it at Control Panel > Programs. From there, uncheck the checkbox for the Internet Information Services. Once done, click on the OK button to save the changes. Note that this process will get rid of all the related programs, services, and folders from Windows 10. So if you want to, you can just install them later on or use an offline installer from the official site of Microsoft.

Option 2 – Try renaming the inetsrv folder

The next option you can check out to resolve the problem is to rename the “inetsrv” folder. If you have uninstalled IIS from the Windows Features, this should remove the folders as well, however, it didn’t remove the folder then you have to delete the folders that are related to the IIS by following these steps:

• First, you have to boot into the Advanced Recovery Mode and from there, open Command Prompt.
• Next, execute this command to rename the folder from this location, C:Windowssystem32inetsrv: rename C:/Windows/system32/inetsrv/inetsrv.old
• Once done, boot into your computer normally and try to upgrade Windows 10 again, and check if the problem is fixed or not.

Option 3 – Try to move the folders related to IIS to a different drive

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, look for the Application Host Helper Service from the list of services and stop it.
• Once done, take ownership of the “WinSxS” folder and then move the *windows-iis*.*” folders to another drive. You can just search using the “*windows-iis*.*” keyword in the Start Search.
• Next, tap the Ctrl + X keys and paste the folders to another drive.
• After that, start the update process for Windows 10 again.

BIOS is software that is running in a chip located on your motherboard, you can enter BIOS usually by hitting DEL once the computer is turned ON but this sometimes varies and it depends solely on the motherboard manufacturer. Inside BIOS you can configure your computer components and set up some other important things including passwords for BIOS itself or for the entire system. Password itself is meant to protect access to BIOS from other non-technical users or to prevent access to the system from other people if for example computer is in one household and you would like to be the only one having access to it. However, passwords can be forgotten, and sometimes you can even purchase a second-hand computer with a password on it. In this guide, we will lead you through ways on how to remove your BIOS password so you can regain access to your BIOS settings.

1. Use Manufacturers master password

   Most motherboard manufacturers have built-in a couple of master passwords for BIOS access. If your motherboard has one you can easily find it on the manufacturer's website. Use the master password and remove other passwords inside BIOS, save and exit.

2. Remove CMOS battery

   If you could not find the manufacturer's master password or your motherboard model does not have one remove the CMOS battery to reset BIOS. Note that this method will reset the whole BIOS not only the password. Open on side of your computer casing and locate the round battery on it, do not worry, there is only one battery so you can not make mistake. Remove the battery and leave it outside for around 20 to 30 minutes then place it back as it was, CMOS is reset now and you can access BIOS.

3. Reset BIOS via jumper

   If you want to remove only the password and do not touch other BIOS setting you can locate the BIOS password reset jumper. How the location of this jumper and position is different from the motherboard to motherboard we can not cover them all here and it is advisable to read the manual or find information on the official manufacturer's website.

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.

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.

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.
