Microsoft Finds New Way To Block Bad Drivers From Making It To Windows Update [2021]

This stop error is commonly caused by corruption in the NTFS file system or bad blocks (sectors) on the hard disk. Corrupted drivers for hard disks (SATA or IDE) can also adversely affect the system's ability to read and write to disk. Run any hardware diagnostics that are provided by the manufacturer of the storage subsystem. Use the scan disk tool to verify that there are no file system errors. To do this step, right-click the drive that you want to scan, select Properties, select Tools, and then select the Check now button. Update the NTFS file system driver (Ntfs.sys). Apply the latest cumulative updates for the current operating system that's experiencing the problem.

Microsoft Finds New Way to Block Bad Drivers from Making It to Windows Update

This stop error code is caused by a faulty driver that doesn't complete its work within the allotted time frame in certain conditions. To help mitigate this error, collect the memory dump file from the system, and then use the Windows Debugger to find the faulty driver. If a driver is identified in the stop error message, disable the driver to isolate the problem. Check with the manufacturer for driver updates. Check the system log in Event Viewer for other error messages that might help identify the device or driver that's causing stop error 0x133. Verify that any new hardware that's installed is compatible with the installed version of Windows. For example, you can get information about required hardware at Windows 10 Specifications. If Windows Debugger is installed, and you have access to public symbols, you can load the c:\windows\memory.dmp file into the debugger. Then refer to Determining the source of Bug Check 0x133 (DPC_WATCHDOG_VIOLATION) errors on Windows Server 2012 to find the problematic driver from the memory dump.

Windows Security has reputation-based protection that can help protect your PC from potentially unwanted applications. Potentially unwanted app blocking was first introduced in the Windows 10 May 2020 update and is turned on by default for enterprise customers, but off by default for consumers.

Microsoft is acutely aware of the BYOVD threat and has been working on defenses to stop these attacks, mainly by creating mechanisms to stop Windows from loading signed-but-vulnerable drivers. The most common mechanism for driver blocking uses a combination of what's called memory integrity and HVCI, short for Hypervisor-Protected Code Integrity. A separate mechanism for preventing bad drivers from being written to disk is known as ASR, or Attack Surface Reduction.

The next option is not practical but can temporarily block a feature update too. You can set your network up as a metered connection, which prevents large updates from downloading. Open Start > Settings > Network & Internet > Wi-Fi, click your network connection, then toggle on Metered Connection. You can also do this for wired connections in Windows 10 version 1703 or later.

Driver corruption is a common cause of blue-screen errors. Drivers that are too old can cause problems as well, usually affecting compatibility or performance. Keep your system updated through Windows Update, or by manually downloading from the manufacturer. If no updates are available, you're stuck with whatever drivers you have, although re-installing them from the Device Manager should help.

Run Windows Update to let the operating system scan and update your drivers automatically. "Optional Updates" are listed below the recommended ones and this is where you'll find drivers. Click beside each driver to select it and click "OK" to confirm. Alternatively, launch the Device Manager from the Start menu and right-click the outdated driver. Select "Update Driver Software."

Below is a list of solutions that you should complete until the SYSTEM_SERVICE_EXCEPTION error disappears. The most obvious solution is to update your drivers and run a Windows 10 file system check for errors, however, it's crucial that you follow all the steps below to avoid this error from happening in the future.

Update, March 24, 2017: Originally published in January 2017, updated on March 2017. This guide has been updated with alternative method to block driver updates using Windows Update, because Windows 10 removes the option from the Settings app.

Previously one would choose the settings to update windows and device drivers. However, after the release of Windows 10, most updates are forced on your system. Apart from the Windows Build updates and forced hot fixes, Windows 10 now updates your device drivers in order to keep your system working at the highest efficiency. This is because Microsoft noticed that most problems on Windows 10 were caused by bad or outdated drivers.

The idea is to disable automatic installations and delete the already updated drivers. We will then install new drivers manually. Since the system is denied from making changes to the driver, it will now not be able to install Realtek Audio Manager.

Security is important, but it was never going to be realistic to limit Windows 11 to such new PCs. People will install it and use it regardless. If Microsoft really cares about security, blocking those systems from getting security updates will just mean a whole bunch more vulnerable PCs out in the world, primed to spread phishing schemes and DDOS attacks and so on. They will be Microsoft's problem whether the company likes it or not. 076b4e4f54
