Fix Error Code 0x80090016 for PIN and MS Store

Error Code 38 – What is it?

Error Code 38 is a device driver error that users encounter on any Windows 2000 operating system and its following versions.

It occurs when the peripheral device that you connect to your PC cannot be accessed due to an inability of the Windows system to acknowledge the driver as a previous record of the driver being loaded is found in its memory.

It is a common error that users come across and appears on your PC with the following message:

“Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)”

Solution

Error Causes

Error Code 38 is prompted when incomplete program files are left in the Windows system which damage or corrupt its files. There are various factors that contribute to this, some of which are:

• An incomplete program installation
• An incomplete program uninstallation
• Hardware is not removed properly
• System recovery from viruses
• An improper system shut down

The above triggers are very likely to create incomplete files within the Windows registry thereby leading to its damage and corruption.

This is especially true in the case of your PC when it has recovered from viruses when using anti-virus software. The anti-virus in its effort to remove the virus also could remove the files which contain them thereby increasing the risk of the error code.

These damaged files can severely impact the health of your PC and are imperative to fix it immediately to prevent further problems.

There are instances when instead of fixing problems the Windows Update brings you problems on your Windows 10 computer. You might even see some pending Windows Updates which for some reason, refuse to install no matter what you do. The good thing is you won’t have to deal with those failed and pending updates that are incompletely downloaded to your PC as you can actually delete them. Follow the instructions prepared below to delete the failed and pending Windows Updates.

Step 1: The first thing you have to do is delete all the contents in the Temporary folder

• Tap the Win + R keys to open the Run dialog box.
• Next, type in “%temp%” in the field and hit Enter or click OK to open the Temporary folder.
• From there, select all the folders and files within the Temporary folder and then delete them all.

Note: %temp% is one of the many environment variables in Windows that could open the designated folder by Windows as the Temporary folder which is usually located at C:\Users[username]AppDataLocalTemp.

Step 2: Next, remove the pending.xml file

• Go to the C:\Windows WinSxS folder.
• Once you’ve opened the folder, look for a file named “pending.xml” file and right-click on it and you can either rename it or delete it.
• After that, the Windows Update should delete the pending tasks and build a fresh new update.

Step 3: Delete all the contents of the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, got to the C:\Windows\Software\Distribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Step 4: Try resetting the catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
