[MOD POST] Having trouble with Secure Boot? Check here first

4 Upvotes

Hello,

The expiration of the 2011 Microsoft KEK CA and the 2011 Microsoft UEFI CA certificates at the end of June 2025 has caused problems with Secure Boot on computers for various folks who have not been able to apply a UEFI (BIOS) firmware update for various reasons.

Because the steps for updating firmware vary not just from manufacturer to manufacturer but between individual models as well, it can be difficult to provide specific assistance and guidance in updating your firmware unless the person helping you has the same hardware.

Below is a list of manufacturers, their Secure Boot certificate update guidance, and links to their support forum(s) or subreddit(s). You may wish to try asking in these places first for expert guidance in updating your firmware, as the people there are going to be a lot more familiar with your device.

NOTE: Please check back periodically for updates to this list.

If you have an update for a manufacturer, please reply with it and we will get it added to the list above.

What to do if no Secure Boot certificate update is available from your manuafacturer

If your manufacturer does not have an update, not all is lost: You can still manually install the 2023 Windows UEFI CA certificate update, by issuing the following two commands from an elevated PowerShell (filename: POWERSHELL.EXE) prompt:

REG.EXE ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x5944 /f Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"   

Then restart the computer and allow the update to be applied.

NOTE: Two (or more) reboots may be required for installation.

Once completed, you can verify the new certificate has been installed by issuing the following command at an elevated PowerShell prompt:

([System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Windows UEFI CA 2023')

If the certificate has been installed installed, the response back will be "True". You can also use that same command to check if the certificate is already installed.

我購買了一台新的Honor Magicbook pro 16 U5-338h筆記本
我的使用環境只適合睡眠,一天下來會有多次闔上蓋子開啟蓋子的動作
休眠喚醒對我來說時間太長了
我開始認真的研究關於S0現代待機的問題,我已經將會把我喚醒的程序都關閉了
並且已經關閉S0的聯網功能
但是偶爾還是會發生電腦睡眠時過熱,系統保護自動轉成休眠的狀況
最後我發現一個狀況是當電腦已經在休眠狀態並且是接上電源,我要移動到下一個辦公地點我會直接移除電源,後續使用電腦就會發現已經過熱系統保護進入休眠
整個過程中只有3-5分鐘
查看了system power report
有個unknown 消耗了9600mW然後就過熱轉休眠了
我已經排除了會讓我系統喚醒的各個因素
但是針對這個拔掉電源的狀況,有沒有更好的設定方法,能讓系統不會過熱保護,我需要我還在工作的狀態下每次打開筆記本都是隨時能快速喚醒並進入之前的工作狀態

Ive only had it for about 2 months and ever since the newest software update, it has been a bit laggy and it has also been acting up by randomly blasting the fans for a few seconds even when I am just browsing? Im not sure if this is related though.

I do have warranty, im thinking of handing it in if I can't find a solution, please help!!

Microsoft Account Compromised

0 Upvotes

I think my Microsoft account was compromised after I entered a Microsoft verification code while verifying on a Minecraft server.

When I tried signing in, Microsoft said my original email address wasn't associated with an account anymore.

I don't have a recovery phone number or backup email linked to the account. I've tried Microsoft's account recovery form, but I can't proceed because it asks for an email address I don't know. I've also been unable to reach support because the human verification keeps failing.

I am able to provide proof I own the account if Microsoft support actually worked.

Microsoft Account Linked to an Unknown Account and Unable to Recover It for Months

Thumbnail
gallery
0 Upvotes

Hi everyone, I'm desperately looking for help recovering my personal Microsoft account. I've been trying for months without success, and now my data is at risk.

My Microsoft account uses my Gmail address, but somehow it appears to be associated with an unknown email/account that I don't recognise. I've repeatedly tried Microsoft's account recovery process, but I haven't been able to regain access or get a resolution.

Recently, my laptop died. I removed its SSD and connected it through an enclosure, only to discover that the drive is locked by BitLocker. My Microsoft account may contain the recovery key, but I cannot access the account to check.

My OneDrive files and OneNote notebooks contain years of important personal information. I can still see some OneDrive files on my phone, but both accounts are asking me to sign in again, and I cannot authenticate.

I'm looking for answers to three questions:

  1. How can I recover my original Microsoft account when the standard recovery process has failed repeatedly?

  2. Is there a legitimate way to escalate this issue to Microsoft support?

  3. Could recovering my account help me retrieve my BitLocker recovery key and save my data?

I've been struggling with this for months, and I'm genuinely worried about losing everything. Any advice, personal experience, or legitimate recovery options would mean a lot to me. Please help me figure out what to do next.

Thank you!

Windows What Program To Blur Out Sensitive Information In PDF Document?

0 Upvotes

I have to send in a sensitive document by email.  There are a few things on that document I want to blank out or cover.  When I mean blank out or cover, I do mean like I'm doing this obviously where the receiving person obviously can see that.  

I have a windows laptop.  Does anyone know what program I can download and use for this?  When I download a PDF file, by default it opens with Microsoft Edge PDF on my computer.  I normally use chrome for web browsing.

If I download Adobe Reader, can I do this?  Do I need an Adobe Reader account?  Do I need to pay a subscription for this?  I only need to do this once.

What other program or sites can I use for this?  I'm not sure I would want to upload a document on a website to do this as it might not be safe?  I do have some sensitive information on it which is why I want to blank it out.  I wanted to do it initially with paint but I can't open this file in paint because it's PDF.

I will do this on my windows laptop or chromebook.

I just noticed I could edit the file by clicking Draw on the PDF file that is opened on Microsoft Edge. I could just draw a line through it and it covers it but obviously it isn't neat compared to like if you resize a rectangle and have it cover whatever sensitive information you want to cover. Is doing that fine or it's better with a regular program where the blurring of it looks even and neat?

-suitable for graphics and design

-for gaming & computing in general

-would run old&moded games

-studying with sources,tabs,apps,files that might crash some old stuff ig (aka my current laptop)

-maybe a couple of side works, organisation.

-⚠️⚠️to be a long-term investment because my broke self cannot afford this again for a long time.

And after years of suffering with what is allegedly a laptop my fraud of a "laptop" I'm finally prepared (with no more than a 1100 sterling pounds bcz I'm a broke student and this is the fruit of my labour.

I heard about the ASUS V16,ASUS TUF Gaming A15 too but don't have enough experience to compare properly because they don't sound that far different.

Also if possible where is best to buy them (UK,England)

Windows Laptop display showing dark lines after exposure to cold. Should I be worried?

Thumbnail

0 Upvotes

Hi, I’ll keep this short.

I left my laptop in a very cold car overnight. It was packed in its laptop bag, and I tried to make sure it wouldn’t get too cold.

This morning, when I opened it, I noticed these lines on the screen (there are similar lines in the other bottom corner, just a little shorter).

I shut it down immediately. While doing so, I noticed that the lines were also faintly visible when the screen was completely black.

About half an hour later, I briefly checked to see if anything had changed, but I didn’t notice any significant difference.

I’m wondering if it could be caused by condensation or moisture, but I really don’t know much about technology.

Could anyone help me figure out what might be causing this and what I should do? Is there a good chance the lines will disappear on their own?

Honestly, as long as the laptop continues to work, I can live with the lines for now. I’m just really worried because this is currently my only laptop, and I need it to work on important documents.

Thank you so much for your help!

Secure Boot disabled

2 Upvotes

Hello everyone,

I installed Call of Duty on my pc and to be able to play it said I needed to update my BIOS version so I did that, I tried to play again and then it said the same but something else aswell "secure boot needs to be enabled". Well turns out that when I installed the newer BIOS version, it disabled secure boot. I have tried for 2 hours to turn this back on, but nothing works.

In the image above you can see that secure boot is enabled BUT it's greyed out, loading the HP factory default keys also didn't work after restarting twice.

At this point I genuinely have no idea what to do and I do not wanna mess with the TPM settings, can anyone help me?

System information:

CPU: AMD Ryzen 5 4600G

GPU: NVIDIA GeForce GTX 1650

RAM: 16GB DDR4

Windows 11

TMP 2.0, ready to use

Windows My pc is possessed.

So the D key on my keyboard is bugged, it’s the only key on my keyboard that when I press it it doesn’t type the D. Every other key will type, but almost every time i press it, it makes me pc go ballistic, then it starts spamming the F key, the S key, the B key, and a few other keys and opens a bunch of windows repeatedly until i unplug my keyboard. I’ve also bought a brand new keyboard and it’s doing the same exact thing. I actually wouldn’t say every time I press the D key it does it but 9/10 times it will make it initiate.

It’s been like this since Thursday and I’ve tried everything. I’ve factory reset, deleted and redownloaded the drivers, unplugged it for a few hours, sticky keys and all those settings are turned off as well. I’m so lost. I need help it’s stressing my tf out.

Windows ASUS storage information, not showing up

So I was trying to do some schoolwork and my PC just kept shutting down. Didn’t brought me to the UEFI BIOS utility EZ mode. Is says the storage information has nothing underneath it and all the boot has nothing either. I’ve tried unplug and plug it back in restarting it even taking the SSD card out and cleaning it up a little bit and putting it back in. I really have no idea what I’m even supposed to do. I spent like the past hour looking up YouTube videos and stuff and still hasn’t helped. Do y’all know what I can do? Do I have to replace my entire SSD card?

HP 15s-eq2132AU BIOS Administrator Password Issue — CMOS Reset Didn't Help, Need Advice

1 Upvotes

Hi everyone,

I have an HP 15s-eq2132AU laptop, and I'm facing an issue with the BIOS administrator password. I'm looking for help from anyone who has experience with HP laptop BIOS security.

The problem:

  • Whenever I try to access the BIOS or perform certain firmware-level operations, the laptop asks for an Administrator password.
  • I don't know the password.
  • After entering the wrong password three times, the laptop restarts without displaying an error code or any further instructions.
  • Windows still boots and works normally.

Things I've already tried:

  1. HP Windows + V reset procedure: I tried the Windows + V key combination to reset the CMOS/BIOS settings. The reset procedure appeared to work, but the administrator password was still there.
  2. Booting Linux from a USB drive: I created a Linux bootable USB and tried selecting the UEFI USB boot option. However, selecting it caused the laptop to restart instead of booting Linux.
  3. Windows is still working: I can boot into Windows normally. I also have around 100 GB of unallocated space reserved for installing Linux.

What I need help with:

  • Is there a legitimate way to recover or remove the BIOS administrator password on this specific HP model?
  • Does the Windows + V procedure normally leave the administrator password intact?
  • Could the BIOS password be preventing the laptop from booting from my Linux USB, or is that likely a separate issue?
  • Is there an official HP recovery procedure or another safe method I should try?

I'd appreciate advice from anyone who has dealt with this issue on an HP 15s-series laptop. Please suggest model-specific solutions if possible.

One more question — Is HP's ₹499 service worth it?

HP has quoted me ₹499 for assistance with this issue.

  • Is paying ₹499 worth it for removing the BIOS administrator password?
  • Will the password be removed permanently, or is ₹499 only a diagnostic/inspection fee?
  • Has anyone in India used this service for an HP 15s-series laptop? What was the final cost, and did the solution work permanently?
  • If HP cannot remove the password without replacing the motherboard, will they tell me before charging for any additional work?

I'd like to understand the actual outcome and total cost before paying.

I'd prefer to avoid risky methods that could brick the laptop or damage the firmware.

Thanks in advance!

Is there no hope?

Post image
5 Upvotes

From what little I've actually understood from the research I've done, is there nothing else that can be done to eliminate this? The computer was from a friend, no clue where they got it from and they didn't even know it worked. So nothing is needed or important within the laptop, I was hoping to use it as a way for my 2 boys to watch Netflix and Amazon or YouTube and simple streaming stuff, on their non-smart TV within their bedroom. (Basically just plug the HDMI & wireless mouse/keyboard in and use the TV as the monitor) So factory reset or anything similarly is an option. Really anything is an option I suppose, cuz from what I've read, it's basically useless unless I figure out the password someone else created, or open the system up and do something inside that is outside my skill set and ability..

So basically I'm just checking that I'm not missing something or someone doesn't have a magical trick that can salvage this?

It's older and the screen is busted up and I didn't pay anything for it. Just would have worked for what I needed it for, and would have saved me the time, effort, and little bit of money it would take for me to find some kind of substitute for my boys..

I'm open to anything since right now, it's just a paperweight for me...

Computer is: HP pavilion x360 m Convertible

Model 11m-ap0013dx

P.s. unfortunately I am basically computer/electronics illiterate and nincompoop.

Thank you in advance.

Here's to hoping there's someone with a miracle key to solve my problem..

The only way I can is taking the motherboard battery out and back but then it resets the settings back to default and csm and the loop continues. I have tried getting into bios every way possible, using cmd prompts and doing it in the settings. I also know this isn’t a hardware issue as I used to have this on my pc when it was on windows 10.
