The backup completed but some files were skipped.” You try finding out the reason and you hover over to the Options button beside the message, then you get to read the following lines: “Check your backup results. The backup completed but some files were skipped. View skipped files.” Upon clicking the “View Skipped Files” option, the backup error 0x80070002 pops up on your screen and you’re left scratching your head, wondering what you’re going to do now.

Solution

Error Causes

There are multiple error logs that you will encounter in backup error 0x80070002 as per different conditions. The two most common cases in which this error shows up are stated below:

Case 1

You will see the following message when you press “View skipped files”: “Backup encountered a problem while backing up file C: Windows/System32/config/systemprofile. Error: (The system cannot find the file specified. (0x80070002))” You will face this case if you have backed up a library that included custom folders that were located in your user profile.

Case 2

Upon pressing “View Skipped files” you will encounter the below-mentioned messages: “Backup encountered a problem while backing up file C:/Users<User>AppDataLocalLow. Error: (The system cannot find the file specified. (0x80070002))” “Backup encountered a problem while backing up file C:/Users<User>Contacts. Error: (The system cannot find the file specified. (0x80070002))” “Backup encountered a problem while backing up file C:/Users<User>Searches. Error:(The system cannot find the file specified. (0x80070002))” You are likely to encounter any of these messages in case:

• The Windows Backup program is trying to back up your files in either one or all of these folders (LocalLow, Searches, Contacts).
• All three of these folders don’t exist in your system.

Keep in mind that all three of these folders exist due to the installation of certain programs and applications on your system.

Notes

The backup error 0x80070002 is also found to occur while using USB devices instead of storage devices. Other occurrences include the times when input/output (I/O) operations are performed on the USB device, which results in failure.

Further Information and Manual Repair

To make sure this issue is resolved, you will have to follow either one of the following solutions as appropriate to your situation:

Solution for Case 1

1. Ignore the error. The store files of the custom library in your user profile will not be created as backups.
2. Transfer the library folder from where it currently exists to a place outside its current folder (user profile). For instance, you can move the library folder to an entirely new destination such as “C: My Folders”
3. Remove the library folder from the list of files that you are backing up using the Windows Backup program. Then, add the original place of the library’s content in the list.
4. Go back and check step two. If carried out successfully then add a link to the folder you moved from the library. Check to see if the backup includes the library folder. To make sure, you have to do as follows:

• Go to Start and select your username.
• Hover across to the folder you wish to move, right-click on it and select “Cut”.
• Head to the navigation pane and search for the area you will store the folder in, right-click and select “Paste” so that the folder is moved to that location.
• Right-click on the folder that you just moved and select “Copy”.
• Go back to Start, select your username, right-click any vacant space in your folder and select “Paste Shortcut”.

Note: If you want to store the folder in a different place other than the folder in which it currently exists (user profile), you will need to create a new folder. In order to do so, go to the Windows Explorer menu and look up the root of the drive. Hit “New Folder” and then choose edit to change its name. You can set it as any name for instance, “My Folders”.

Solution for Case 2

You can ignore this error safely. However, if you wish not to see this error in the future during your backup operations then you will need to carry out the following steps:

1. Create all the folders listed in the error message including LocalLow, Contacts, and Searches.
2. Remove all of these folders from the Backup settings to make sure they aren’t being backed up then add the folders which are in their original place. To carry out this procedure, you will have to follow the below-mentioned steps:

• Head over to the Control Panel and open “Backup & Restore”.
• Go to the Backup section and select “Change Settings”.
• Click Next in the Setup backup dialog box.
• Select “Let me choose” in the dialog box termed “What do you want to back up” then proceed by clicking Next.
• Expand Data Files, expand <user> Libraries, expand Additional Locations then proceed by clearing out the AppData Folder, searches, and Contacts checkboxes.
• Expand Computer as well as the item for your system drive (expand Local Disk (D:)), expand users, expand <user>, then go to AppData, Searches and Contacts and mark them if they are present.
• Proceed by clicking next and select “Save Settings” then exit.
• Back to Backup & Restore, select Back up now and your new backup will begin proceeding. The entire process will be complete without any errors now.

If you encountered an error message that says, “Unhandled exception has occurred in your application”, when you start your Windows 10 computer, read on as this post will guide you on how you can fix it. This kind of error usually appears in a Microsoft .NET Framework window and it mostly pops up as soon as you turn on your computer. Here’s the complete context of the error message:

“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”

When this error occurs, your computer may freeze or display other suspicious behavior at times. Either way, there are several options you can check out in this post to resolve this issue, so read on. This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• 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”.

• 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.)
• Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
• Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Microsoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use. The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability. We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.

Back to Windows 10

How we can expect some buggy build of Windows 11 if you prefer a stable system over new features maybe best decision would be to switch back to Windows 10 until the new OS hits official release.

Switching from dev build channel to beta channel

Another solution, if you do not want to deal with too many issues, is to switch from Dev build channel to beta where things will be more stable. Follow the guide below in order to quickly switch to the beta channel. Following instructions only apply to Windows 11 installations that are linked up to the Windows Insider program, not clean installation of OS.

1. Press ⊞ WINDOWS + I to open settings
2. Inside settings click on Windows update
3. In Windows Update click on Windows Insider Program
4. Inside click on Choose your Insider Settings
5. Click on the button next to Beta Channel to select it (you can switch back to the Dev channel here if you change your mind)

The setting will be saved automatically and from now on you will only receive beta channel updates.
