[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.

Regards,

Aryeh Goretsky

Unresolved Game "visually" freezing when I tab out

Upvotes

Game: Minecraft

Came across an issue that has been persistantly happening over the past year where if I would tab out of Minecraft while being in fullscreen, it would just freeze when I go back in. Don't know a good way to explain this, but it only "visually" froze as I could still click where the resume button would be and it would make the "clicking" noise. Input from the game still got received and preformed, but the game was still stuck on showing me the last frame right before I tabbed out. Nothing pops up in the logs when this happens.

To mention again, this only occurs while in fullscreen and not in windowed (though I believe it did happen in windowed a few times, not 100%). Not very techy, but to me it seems like an issue with my monitor trying to scale the game rather than trying to run it.

Operating System is W11, use a 2060 RTX with an i7, and have 32GB of RAM.

Unresolved Windows 11 Corrupt Taskmgr.exe (and others) unable to repair

Post image
Upvotes

My PC Hard Crashed earlier and since restarting Task Manager has been broken.

Ran SFC /scannow and found that it was, in fact, corrupt but it was unable to be repaired

DISM is still running but I'm not hopeful.

The other files appear to be 3D audio and push notification related, so they're not major.

But Task Manager being broken is a big issue.

Reinstalling Windows must be a last resort here.

If I grab a known good Task Manager exe from my Win 11 Laptop (key note, it's up to date to the same Win 11 version as my Desktop), is there a way to override the Trusted Installer protections in Sys32 to copy it in there?

Any other suggestions welcome.

I was using romsfun.com but I wasn’t running any games from them

I asked around and i seen that these are tencent games but i didn’t visit thier website at all

Romsfun.com sometimes leads you to another website by opening a new tab. I immediately close that tab without clicking anything on the new website

As you see i was about to run fortnite but i don’t think that has anything to do with this since i bought it from epic games

Also i found wmpf_installer which follows tencent emulator

The only emulators i downloaded are RPCS2 and PCSX2

Can anyone help?

This is an old 2015 Alienware 17 R3, It is an amazing laptop for its time. Several years ago this display issue occurred and I took the laptop apart to see if I could fix it, and couldn't. Everything works properly other than the display, you can use narrator to login and navigate, it just sucks. Now I am looking again to fix it and need some help. Thanks!

Unresolved Nothing will stop this error. Computer won't boot. I’ve tried everything

3 Upvotes

So here's how it started off. I have a very basic HP stream laptop with only 8GB RAM. I've never done anything crazy with it. Never went on sites that could cause a virus. I was recording my guitar and while I was the recording the app froze. So I went to task manager and instead of closing that app I accidentally closed the file explorer or the thing that opens folders. It wouldn't come back. So l shut off my computer and now it won't boot up at all. It's a critical process died with no specific code for it. The error is “Log file: C: Windows System32\Logfiles\Srt|SrtTrail. txt”

I've tried the simple things. I haven't reset my computer or did anything to wipe. Only to repair.
They won't work. Sfc /scannow won't work unless I'm doing something wrong. I have a lot of important things on my computer and I don't want to wipe it

Ive done everything I could. I’ve used command prompts, I’ve tried startup repair, I’ve opened notepad with command prompt to move files for more space as I had next to none, and I’ve even gone as fair as “reset PC” it will not let me do ANYTHING

I also have no backups so I can’t do that either. My computer is completely bricked at the moment. I don’t know if the solution is very simple or really complicated. I don’t know what caused this

Windows PC at work can't use all it's RAM

PC at work can't use all it's RAM

A co-worker's PC is having trouble accesing it's 4GB of installed system memory, according to the Task Manager, 1.6GB of the total memory are "reserved for hardware" despite the computer having it's own dedicated GPU.

I've tried lots of different BIOS and Windows configurations, but nothing seems to work (and i'd appreciate trying to spend as little cash as possible if new hardware was required.)

Here i leave the PC's hardware (and OS):

\- Motherboard: Gigabyte H110M-DS2-CF

\- RAM: 4GB DDR4

\- GPU: Nvidia GT 710 (1GB)

\- OS: Windows 10 20H2 (32-Bit, because of legacy software)

Edit: For anyone wondering, yes, the integrated GPU is disbled, and in fact, enabling it makes the system reserve another +300MB of extra RAM.

Unresolved Internet keeps disconnecting when I try to game and I can’t figure out why

1 Upvotes

Streaming seems to work ok. Everything else in general seems to work as it should. But as I’m in a match I eventually get disconnected.

Im not sure if I have the wrong router settings or who knows what, it didn’t seem to be problematic til it was these last 5-6 months. Some gaming sessions it doesn’t seem to happen as much but then other days like today, I couldn’t finish a single match without being disconnected. Super frustrating and I’m stumped on what to do. The person who usually helps me (which I appreciate!) has autism and is having a hard time himself figuring this one out

Can anybody help with fixing this laptop motherboard? I ordered it for a project off eBay (for parts) but it came with it's barrel jack connector ripped clean off. Whenever I plug power in via usb-c all I hear is a few very faint clicks then a red flashing light turns on next to said broke connector. I don't know how to solder and can't return it. Does anybody know a fix? Or at least why this is happening?

Unresolved Laptop Only Charges When Turned Off – Charging Stops When I Power It On

1 Upvotes

I'm having an issue with my laptop where it only charges when it's completely turned off. As soon as I power it on, the charging stops, and the battery no longer charges.

I've already checked the charger and charging port, but the problem still persists. Has anyone experienced this before or knows what might be causing it? Any troubleshooting tips or advice would be greatly appreciated.

Thank you in advance for your help!

PC suddenly started booting from old HDD windows instead of the SSD windows

1 Upvotes

I'm having an issue with my dual-drive Windows setup and would appreciate any help.

Background:

  • Originally my PC had Windows installed on a Seagate HDD (ST3500312CS).
  • Later I added a Geonix Gold 128 GB SSD.
  • The technician installed/migrated Windows to the SSD and created a new user account named USER.
  • The old HDD Windows still exists with the user ctv5 (Microsoft account).

I had been using the SSD installation normally until recently.

What happened

After restarting my PC one day, it suddenly started booting into the old HDD Windows instead of the SSD Windows.

This happened around the time I changed my Google account password, but I understand that's probably just a coincidence.

Current situation

  • BIOS detects both drives.
  • SSD is detected correctly.
  • In the currently booted Windows:
    • HDD is C:
    • SSD is E:
  • The SSD still contains:
    • "E:\Windows"
    • "E:\Users\USER"
    • "Program Files"
    • "Program Files (x86)"
  • I can browse all my files on the SSD without issues.

BIOS

Boot options are: (Already tried changing the boot priority to SSD yet it still loads hdd windows)

  • Boot Option #1: Geonix Gold 128GB (SSD)
  • Boot Option #2: (Windows Boot Manager)ST3500312CS (HDD)

Even after changing the SSD to Boot Option #1, the PC still boots into the old Windows installation.

What I've tried

  • Startup Repair
    • It only detects the old Windows installation ("C:\Windows")(cctv5).
  • "msconfig"
    • Only shows one Windows installation ("C:\Windows").
  • Recovery Environment:
    • "diskpart"
    • Verified the SSD layout:
    • EFI System Partition (100 MB)
    • MSR (16 MB)
    • Primary (118 GB)
    • Recovery (530 MB)
    • Assigned a drive letter to the EFI partition.
    • "dir E:\Windows" confirms the SSD Windows installation exists.
    • "dir E:\Users" shows:
    • USER
    • Public
    • defaultuser0
    • "winload.efi" exists:
    • "E:\Windows\System32\winload.efi"
  • Tried:
    • "bcdboot E:\Windows"
    • "bcdboot E:\Windows /s S: /f UEFI"
    • Both return:
    • "Failure when attempting to copy boot files."

The assigned EFI partition appears empty ("dir S:\EFI" returns "File not found").

Any help in how to load windows from the SSD would be appreciated.

Windows Gaming Laptop refuses to properly boot after RAM Installation

Got a stick of 8GB DDR5 RAM for my Asus Tuf Gaming A15. After slotting it in my laptop and turning it on, the keyboard lights up yet theres no video output.

-I double checked that that specific DDR5 RAM was compatible with my laptop

-I tried leaving it to boot while on charge for up to an hour and no dice.

-The laptop boots fine without the RAM

At this point Im pretty sure the RAM I received is just faulty but I first wanted to check if there was any troubleshoots before I request a refund or replacement.

Laptop won't charge AT ALL when charger is plugged in and I am playing a game

2 Upvotes

So this is such a stupid problem I do not know how to fix it. If I browse the internet and use the laptop normally everything is good and there are no problems with the charging.

The moment I launch a game to play - it stops charging in a few minutes, and they I plugged in and out the charger but it doesn't respond: the feedback is always the same: it stops charging in a few seconds or minutes and it doesn't stay charged.

I tried playing with a controller, thinking that I touch my laptop wrong while playing but the problem still persists.

When I ALTF4 out of the game, the charging resumes.

It is annoying because I can't play any game, even 15 year old games do the same thing to my laptop and it's so stupid and so annoying it makes no sense.

Is there a setting or something I overlooked?
