Fix An unspecified error 0x800700b7

KMODE_EXCEPTION_NOT_HANDLED seems to be connected primarily to a third-party driver, e1d65x64.sys associated with the Intel(R) Gigabit adapter, NIC/Wired network NDIS (Network Driver Interface Specification) 6.x driver. Error is known to produce the dreaded blue screen of death or BSOD. Most usually error is connected with gaming on Windows 10 computer and it manifests itself during gaming sessions. If you are unlucky and you are faced with this unfortunate error we will be happy to try to help you and present with tips and tricks in order for you to find a solution for it. Before you proceed with the provided solutions, be sure you have sufficient disk space on the Windows drive, run Disk Cleanup and then run CHKDSK.

1) Run the Blue Screen Online Troubleshooter

Open Control Panel, change the view setting to icons. Click Troubleshooting, and click “View all” in the tasks pane. Click “Blue Screen”. This opens the Blue Screen Troubleshooter.

2) Run Driver Verifier

1. Start a Command Prompt window by selecting Run as an administrator, and type verifier to open Driver Verifier Manager.
2. Select Create standard settings (the default task), and select Next. You can also choose to Create custom settings to select from predefined settings, or to select individual options. For more information, see Driver Verifier options and rule classes and Selecting Driver Verifier Options.
3. Under Select what drivers to verify, choose one of the selection schemes described in the following table.

   Driver verifier table:

   Option	Recommended use
   Automatically select unsigned drivers	Useful for testing on computers that are running versions of Windows that do not require signed drivers.
   Automatically select drivers built for older versions of Windows	Useful for testing driver compatibility with newer versions of Windows.
   Automatically select all drivers installed on this computer	Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance.
   Select driver names from a list	In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time.

4. If you chose Select driver names from a list, select Next, and then select one or more specific drivers.
5. Select Finish, and then restart the computer.

3) Update network device drivers

Go to the official Intel website and try to find newer versions of drivers, if there are none perhaps you will need to revert back to the previous version.

4) Scan memory for issues

Run a memory test on your system, sometimes these errors can be traced back to a faulty RAM bank.

5) Stop over-clocking your PC

If you have overclocked your PC please reverse it back to its original state and see if that would solve the issue

6) Perform System Restore to the previous restore point

If none of the previous solutions have bared fruit, roll back to a previous restore point and that should solve the issue.

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

What Is Installation Error 1628?

Installation Error 1628 is, as the name suggests, an installation error. When it occurs, a generic 1628 message is displayed to the user. When this message appears, it is either a problem with the install files or an issue with the InstallShield.

Solution

Error Causes

Installation Error 1628 is caused because every Windows-based program or application has been designed that such that it has to be installed on the computer for use. This installation process is important because it not only moves files to the appropriate location on one’s hard drive but also because the process creates registry entries in Windows System files. A vast majority of these programs and applications have a built-in tool that’s responsible for aptly performing this installation. This built-in tool is the InstallShield. This establishes that when this error occurs, it is either because of some unforeseen issue that occurred during the installation process or because of some problem with the InstallShield.

Further Information and Manual Repair

In order to keep this error from occurring in the future, some recommendations are outlined below.

• Check the installation disc and determine if there are any smudges, scratches, or fingerprints on it. If the system is unable to read data from the disc, Installation Error 1628 will be generated. In order to ensure that the Installation Disc is clean, use a microfiber cloth. Dampen it lightly with water and clean the disc. Wipe the inside of the disc lightly in an outward direction, making sure that it is not wiped in a circular pattern. Try to reinstall the application or program after cleaning the disc. The issue should be resolved. However, if it persists, some problems may be with the InstallShield.
• The alternative solution is to repair the InstallShield and the procedure goes as follows.

1. Stop InstallShield’s running process. It may have been crashed and simply needs to be restarted. Now access task manager. Press Ctrl+Alt+Del and the task manager will open. Now go to the processes tab and disable ‘idriver.exe’ and ‘msiexec.exe’ from here.
2. Now go to ‘C: Program Files/Common Files’. Here you will find the ‘InstallShield’ folder. Select ‘rename’ and modify the folder name to ‘InstallShield1’. Confirm rename and start the installation process again. Now Windows will try to re-install any InstallShield files one needs.
3. If the error persists after renaming the InstallShield folder, download the Windows Installer from Microsoft’s website. This file will determine whether or not your version is valid. Old versions often have bugs that cause problems. Your system is now ready to be used.

22H2 update for Windows 11 will arrive later this year and although Microsoft is not releasing anything big there will be some interesting improvements and fixes. We take a look at some that caught our attention.

Phishing protection

One of the most interesting upcoming features is enhanced phishing protection. Microsoft Defender SmartScreen will be upgraded to alert users when they try to store passwords in plain text files and also if they accidentally type in a Microsoft account password on phishing sites.

"These enhancements will make Windows the world's first operating system with phishing safeguards built directly into the platform and shipped out of the box to help users stay productive and secure without having to learn to be their own IT department,"

Microsoft

File Explorer gets tabs, a modern sidebar, and contextual suggestions

Finally, Windows File explorer is getting tabs that will allow much easier management of folders and files inside it.

It is confirmed that Microsoft is also working on a new 'HOME' sidebar that should be modern in design and in features including OneDrive so you can find everything in one place.

Pinning of favorite files was also mentioned so you can easily pin favorites for quick access.

Full-screen widgets

Windows 11 has brought back widgets in a new way and from all the feedback users are loving them. Currently, you have a widget sidebar on the left part of the screen where you have your chosen store widgets but from the Microsoft teaser, we will have soon the option to have them in full screen.

If you are using a widget for reading news, blogs, etc. this feature will be very good since you will be able to use your whole screen for information and not just a part of it.

Suggested actions

Another new feature is 'suggested actions' which is going to be particularly useful in apps like Microsoft Teams. With this new feature, you can highlight a date in a Teams message and Windows will suggest actions.

For example, if you highlight a date, you'll see a recommendation to create an event in Microsoft Calendar for that day.
