Fatal error occurred while trying to sysprep

The Windows 10 operating system comes with a user-friendly interface as well as better security features compared to its previous versions. One of these new features is the “Recently Opened Files” feature which displays all the files you’ve opened recently in File Explorer. Although it might seem useful, some users see this as a privacy concern especially if there are other users that use the same computer. If you are one of these users, read on as this post will guide you on how you can disable the “Recently Opened Files” feature in Windows 10. There are three ways you can disable the “Recently Opened Files” feature. You can manually clear the recent files, or disable the feature via Control Panel. You can also do it using the Group Policy Editor.

Option 1 – Manually clear the recent files

The first thing you can do is to clear the recent files manually. Since the information about the recently opened files is stored in the form of cached data, you can locate this data and delete it manually, from time to time. To do that, follow these steps:

• Tap the Win + R keys to open the Run utility and copy this address in the field: %AppData%MicrosoftWindowsRecent
• Next, tap the Ctrl + A keys to select all the items and then tap the Shift + Delete keys simultaneously.
• After that, a prompt will appear where you have to click on Yes. This will delete all the recently opened files in the File Explorer the next time you open it.

Option 2 – Disable the feature via Control Panel

The next option you can try to disable the feature is via Control Panel. Refer to these steps to do so:

• First, click on the Start Menu button and select the Settings icon.
• After that, click on Personalization and then on Start located on the left pane.
• Next, scroll down until you see the “Show recently opened items” in Jump Lists on the Start or the Taskbar and click on it and then toggle it off.

Option 3 – Disable the feature using the Group Policy Editor

If you are using the Windows 10 Pro version, then you have access to edit the functions in the Group Policy. The Group Policy function has the option that can disable all the default services of Windows 10. Note that in this step, you will permanently disable the “Recently Opened Files” feature. So before you proceed, make sure that you really want to disable this feature permanently and not in the meantime.

• Tap the Win + R keys to open the Run dialog box and type “gpedit.msc” in the field and click OK or tap Enter to open the Group Policy Editor.
• Next, on the left side pane, click on the “User Configuration” option and then click the “Administrative Templates” option.
• After that, select the “Start Menu and Taskbar” option and select the “Don’t keep the history of recently opened documents” option in the right pane.
• Now double click on this option and check the “Enabled” option and then click on Apply and OK buttons to save the changes made.

If you are trying to connect your mobile or external device to your Windows 10 computer but suddenly encountered an error saying, “A device attached to the system is not functioning”, read on as this post will guide you on how you can resolve this error using a couple of potential fixes. In this case, it is possible that the connected device is not working for some reason and this error pops up when you connect your device or when you try to move or copy files from your computer to your external device and vice versa. As you can see, the error message is pretty straightforward, and it mostly occurs when you connect plug and play devices such as USB drives, printers, external storage devices, and many more. And when you open the Device Manager to check the device, you will most likely see a yellow exclamation mark on the device which indicates that the device is currently having problems. To fix this problem, there are several options you can check out. You need to check the status of the device or check the compatibility between the external device and the drive types. You also have to make sure that the device is connected properly or check if the device has been formatted properly. For more details, follow the given suggestions below.

Option 1 – Try to check the status of the device

The first thing you can do to get rid of the error is to check the status of the external device, especially if it’s a plug-and-play device. So when your computer boots, check if it is able to detect the device or not.

Option 2 – Try to check the compatibility between the external devices and drivers

As you know, when you connect an external device to your computer, Windows installs drivers to communicate with the device, the same way as any hardware you connect to the motherboard and if the driver ends up getting corrupted or is incompatible, then you need to update the device driver. To do that, follow the steps below.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the driver the external device related to and then right-click on each one of the Device drivers and select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the device drivers didn’t work, you can try to reinstall them instead.

Option 3 – Try checking the hardware connections

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 4 – Check if the device is formatted properly

You might also want to check if the external device is properly formatted especially if you’ve recently formatted it. If a device wasn’t formatted properly, then it’s no wonder why you’re getting the “A device attached to the system is not functioning” error. To fix this, you need to use Disk Management. From there, you can find the devices connected but are not visible. If you are using an admin account, then to fix this error, you have the option to format the drive or create new partitions using the interface. Once you do this, it should resolve the problem.

Option 5 – Try to run System File Checker or SFC scan

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

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect your device or copy the files to your external device again and check if the error is now gone.

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.
