A Quick Guide to Resolving Error 0x80070003

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.

Error Code 22 - What is it?

Code 22 is a type of Device Manager Error code. Device manager errors are reported by the drivers causing the problem. It indicates that the devices are disabled in the Device Manager. This error code is displayed in the following format:

This device is disabled. (Code 22)

It looks like a very simple matter to enable a device from the Device Manager interface but if the device fails to load then there are likely greater underlying problems with the drivers. Drivers allow hardware devices to communicate with other hardware devices and the operating system. Drivers contain instructions and operating procedures for devices. Without a driver, a hardware device will not function and may not even appear in the Device Manager.

Solution

Error Causes

Common causes of error code 22 are:

• Device is disabled
• Driver is outdated
• The driver is missing or corrupt
• The previous attempt to update the driver failed
• Device is damaged
• The device is not configured as the default device

This means that though the error code 22 typically indicates that the device reporting the error is disabled but other causes can also be associated with the error occurrence.

Further Information and Manual Repair

Here are some of the best and easy do-it-yourself methods to resolve error 22 on your PC. Try these methods to repair the issue.

Method 1

If the error code 22 is triggered due to a disabled device, then all you need to do to resolve the issue is enable the device. To enable the disabled device, follow these steps. Simply go to the start menu and type Device Manager in the search bar. Now click on the Device Manager and then click Actions. After you Click Actions, double click Enable Device. The Enable Device Wizard will pop up. Follow all the prompts from the Enable Device Wizard. This will hopefully resolve the issue.

Method 2

If method 1 doesn’t work then this means the problem is deeper than you think.  The problem can be triggered by the missing, corrupted, or outdated driver for the device reporting the error. In such a situation it is advisable to reinstall the driver for the device. To do this first uninstall the driver for the device reporting error code 22 then reinstall the driver.

• For this simply click the Start menu, go to the control panel and then click Performance and Maintenance, and then System.
• In the new window, you will then see a tab called Hardware and the Device Manager.
• Double click on the device whose driver you need to uninstall.
• Click on the properties window with a tab marked driver. Then click on the driver you want to uninstall.

To activate changes reboot your PC. Now reinstall the latest and updated version of the driver uninstalled using the Plug and Play feature.

Method 3

The registry cleaner wipes out all the unnecessary and obsolete files damaging the registry and repairs them in a few minutes. Click here to download Restoro.

Taking information from the internet or from other sources usually involves selecting the text, copying it into the clipboard, and then pasting it into your file. In today's modern applications pasting text will most of the time take its formating with it.

By formatting what I am talking about are parameters like font size, line breaks, hyperlinks, font styles, etc. and sometimes you do not want any of these in your file, you would like and prefer to have just plain text so you can format it as you wish.

In order to paste just plain text instead of using the CTRL + V keyboard shortcut, press CTRL + SHIFT + V instead. This shortcut will paste the only text into your file.

Shortcut and Microsoft Word

Leave it to Microsoft to make its shortcut not work in their application. In Microsoft Word, you can only use the standard CTRL + V shortcut, if you press CTRL + SHIFT + V nothing will happen. So in order to paste the only text into a word document, choose to paste special > text only

Other applications

I have tried CTRL + SHIFT + V in various applications like photoshop, illustrator, InDesign, visual studio code, slack, discord, WordPress installations, etc and only one that has not worked for me was Word and office in general so you are safe to use this trick and have desired results.

If you suddenly encountered an error when you try to run the Windows Sandbox that says, “Windows Sandbox failed to start, Error 0xc030106, The virtual machine or container exited unexpectedly”, read on as this post will guide you on what you can do to resolve the problem.
