If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

One of the useful features that came with Windows 10 is the Mobile Hotspot although there’s a downside to it – it drains your battery faster especially if your Windows 10 device is running on battery. Another one of its flaws in the implementation of this feature is that it stays activated even when the connection is idle. In other words, it is still activated even if no devices are connected to it. As a result, it consumes battery life and affects it. There are also instances when it affects the performance of the network connection. At the time of writing, Microsoft hasn’t done anything about this dilemma yet so in the meantime, you can continue reading this post to resolve this issue on your Windows 10 device. You can remedy this Mobile Hotspot issue by running a command in Windows PowerShell. To get started, follow the given instructions below.

Turn off Mobile Hotspot Automatically:

Step 1: The first thing you have to do is to copy the following command:

powershell -windowstyle hidden -command "Start-Process cmd -ArgumentList '/s,/c,net stop "icssvc" & REG ADD "HKLMSYSTEMCurrentControlSetServicesicssvcSettings" /V PeerlessTimeoutEnabled /T REG_DWORD /D 1 /F & net start "icssvc"' -Verb runAs"

Step 2: After copying the command given above, open the Notepad app and paste the command you copied there and save it. And when saving it, select the “Save as” option and its File type as “All files”. Step 3: After that, put “TurnOnTimer.bat” as the file’s name and save it on your Desktop. Step 4: Once done, run the file you just created, and when a User Account Control or UAC prompt appears, just click on Yes. Step 5: After you run the file, it will run a series of scripts in a command line which will turn off the Mobile Hotspot automatically when idle. And that’s how you automatically turn off the Mobile Hotspot when your Windows 10 device is idle. On the other hand, if you want to undo the changes made, you can always do so using the steps provided below.

Turn on Mobile Hotspot:

Step 1: Copy and paste the following command in the Notepad app:

powershell -windowstyle hidden -command "Start-Process cmd -ArgumentList '/s,/c,net stop "icssvc" & REG ADD "HKLMSYSTEMCurrentControlSetServicesicssvcSettings" /V PeerlessTimeoutEnabled /T REG_DWORD /D 0 /F & net start "icssvc"' -Verb runAs"

Step 2: After copying and pasting the command, save it as “TurnOffTimer.bat” on the Desktop. Step 3: Once done, run the file like what you did earlier and select Yes when a UAC prompt pops up. This will run a series of scripts on a command line which will revert the changes back to their default state.

To run it, 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 5 – Try to install the Windows Updates manually

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.
