How to solve multiple BSOD failures after Windows Update?

JennG 0

Hi! My computer told me there was an update this morning. My computer tried installing the updates on its own after I got a black screen with an error - I'm guessing the new BSOD. Since then, I've had multiple other errors, and I'll list them here, in no particular order:

System_Service_Exception (Ox38)

Kernel_Security_Check_Failure (Ox139)

Cache_Manager (Ox34)

Kmode_Exception_Not_Handled (O1xE)

What failed - ndis.sys and tcpip.sys

I tried forcing the computer into safe mode booting and got somewhere, but my computer is severely limited in function now with me not being able to get File Explorer to work and other Windows Updates are giving problems (Install error - 0x800f081f).

I'm really hoping someone can give me the easy fix here so I don't have to go either wipe the system or buy a new computer - both are really not within my budget now!

Thanks so much

Hi,

Sorry you’re dealing with these BSOD errors, especially right after an update. When you see errors tied to ndis.sys and tcpip.sys, that usually means your network drivers or some core Windows files got messed up. Basically, the update broke something important, and now Windows keeps crashing.

Easiest way out is to roll back that update. Since you can get into Safe Mode, go into the Windows Recovery Environment (WinRE). You can do this either from Safe Mode or by letting your computer fail to boot three times in a row. Once you’re in WinRE, head to Troubleshoot, then Advanced options, then Uninstall Updates. Pick the Latest Quality Update first, that’s usually the problem. Uninstall it, restart your PC, and you should be back in business.

Thanks. The problem that I'm having is that the computer is very tempremental - it will do certain things, but with Windows Explorer not working - not sure why that would be impacted, but it is - not everything works.

We can only use the Command Prompt to fix things and try to stabilize the system because you can't even use the usual Windows interface in Safe Mode.

The Command-Line Method (No Need for File Explorer)

You can still get to an administrator command line by using Task Manager. To do this, press Ctrl + Shift + Esc to open it, then go to File > Run new task, input cmd, then check the box next to "Create this task with administrative privileges" before clicking OK. You can move on to the next commands after the Command Prompt window opens.

Step 1: Make the system repairs happen again

Start by forcing another round of system repairs. These commands give you the best chance of fixing the file corruption that is causing errors like 0x800f081f and kernel-related problems. Run sfc /scannow and let it finish, then run DISM /Online /Cleanup-Image /RestoreHealth. Keep in mind that DISM may have trouble if Windows Update components are badly damaged, but it's still important to run it.

Step 2: Use the Command Line to Try the Update Rollback

If you can't get to the graphical "Uninstall Updates" menu in the Recovery Environment, you can try doing the rollback from the WinRE command prompt, which is usually more reliable than doing it in Safe Mode. Wusa commands usually install updates instead of removing them, so your best command-line option is to try a system restore using an available restore point. This is usually the most reliable way to undo a bad update.

Step 3: Use the Command Line to Start System Restore

If you have a restore point from before the update was installed, you have the best chance of getting your system back to normal. To do this, open an administrative Command Prompt and run rstrui.exe, which opens the standalone System Restore interface. Then, follow the prompts to choose a restore point from before the updates from that morning and continue with the restoration. This process often fixes blue screens that happen after an update by rolling back system settings and drivers.

If none of the command-line methods work because the system is too unstable to finish them, the next best thing to do is to make a Windows 11 installation USB on another working computer using the Media Creation Tool. Then, boot your broken machine from that USB. You may need to change some BIOS settings to do this. When you see the option to Repair your computer instead of Install Now, you will have access to the same Troubleshoot and Advanced Options menu, but it will be running from a stable external source. This often lets features like Uninstall Updates or System Restore work when they don't work internally.

Hi JennG,
Welcome to Microsoft Q&A forum. I'm happy to help.

You either have memory problem, or your CPU Memory controller cannot handle the memory well, or drivers conflicted.

To diagnose the problem, try the following suggestions:

Go to BIOS and disable any overclocking and XMP
Disable the "Memory integrity" feature (if enabled)
1. Click the "Start" button and search for "Core isolation"
2. Disable "Memory integrity"
3. Restart your computer
4. Use your computer normally and see if the problem disappears

If disabling "Memory integrity" doesn't work, please do this workaround. Since this is workaround, it may or may not work with you.

Open Notepad

Insert this code

      [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile]
      "SystemResponsiveness"=dword:00000014 
      "NetworkThrottlingIndex"=dword:0000000a
      "LazyModeTimeout"=-

Save as "BSOD-fix.reg" - includes " in file name
Run that file

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Thanks so much, Lucas, for trying to help. When running the registry script that you suggested, this is what I got back. Am I doing something wrong?

Thanks
