If you are frequently experiencing slow loading of folders in your Windows 10 computer, Downloads folder for instance, then you’ve come to the right place as this post will help you resolve such issue. Slow loading of folders is a common problem faced by many users even when they are using the latest hardware like SSDs. So if you experience the same thing, be it with the Downloads folder or other folders on your computer, there is a way to resolve that issue and make the folder load faster. Slow-loading means when you attempt to open the folder, it takes a couple of seconds before it displays its contents. In such cases, you’ll see a green loading address bar that says “Working on it” which can get quite annoying especially if you are in a hurry. And if you notice that this only happens in the Downloads folder, there certainly is something wrong. This kind of problem can occur on SSDs and normal hard drives. The main reason behind the occurrence of this problem is that the folder may have been optimized for viewing photos or other media formats which is why it takes quite longer than usual to load all the files and their thumbnails. However, since the Downloads folder usually contains all kinds of files like documents, zip files, audio/video files, etc. there is no need to optimize this folder for media files only because doing so is only going to make the Windows File Explorer slow in loading the folder’s contents and thumbnails which does not exist for many files.

Option 1 – Configure the Downloads folder

• Right-click on the Downloads folder or the folder you’re having trouble opening.
• Then click on Properties and go to the Customize tab.
• After that, click on the “Optimize this folder for” option in the drop-down menu.
• Next, select General items from the drop-down which might have been set by default to Pictures or Video.
• You also have the option to apply this template to all the subfolders, that is if your folder has any subfolders.
• Now apply the settings and restart Windows Explorer.

Note: Once you’ve completed the steps above, it should now make the folder content display a lot faster than before. Now try to open the Downloads folder which would not take much time as you will see the changes right away.

Option 2 – Run CHKDSK to check your disk for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system including File System Error -2147219196.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

chkdsk /r /f

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.
• Once your computer has restarted, try accessing the file and check if the error persists.

If you’re suddenly unable to launch or open Google Chrome or unable to load web pages, then it’s most likely that the files in Chrome have been corrupted or some plugin is taking up a lot of resources which is why you encounter an error message saying, “Google Chrome has stopped working”. And when you try to check the Task Manager, you’ll see that Chrome is really taking up lots of resources, however, when you check the Taskbar, strangely, you will see nothing. If you are currently facing this issue in Chrome on your Windows 10 PC, follow the given options below.

Option 1 – Kill Google Chrome’s process in the Task Manager

If you aren’t able to open Chrome, then maybe its process is running in the background and you don’t see the browser windows. If that’s the case, you may have to force quit the browser and then try to open it again.

• First, right-click on the Taskbar then select the Task Manager. And if the Task Manager is not responding, you can just use the Alt + Ctrl + Del keys and then select the Task Manager.
• After opening the Task Manager, under Processes, look for Google Chrome’s process which would most likely be named “chrome.exe”.
• Right-click on Google Chrome’s process and then select the End task option.
• Now try to open Google Chrome again.

Option 2 – Try checking if your antivirus program is blocking Google Chrome

There are instances when due to false-positive, a security or antivirus program might block Chrome which is why it failed to open properly. Thus, you can just disable the security program temporarily and then check if you can now open Chrome or not.

Option 3 – Delete the User Profile in Chrome

You can also try deleting the User Profile folder in Chrome. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then copy and paste “%USERPROFILE%AppDataLocalGoogleChromeUser Data” and hit Enter.
• From there, look for a folder named “Default folder” and then copy the folder to another drive as a backup.
• After creating a copy of the folder, delete the Default folder.
• Next, open Google Chrome again and go to Settings > Advanced > Reset.

Option 4 – Disable the Extensions in Chrome

There are instances when issues on a browser are triggered or caused by some problematic extension. To find out which one of your extensions is causing the problem, disable them all first and then enable them back one by one.

• Click on the three-dotted icon for the menu located at the top-right corner of your screen.
• Then click on the More tools option and go to Extensions.
• From there, you will see a list of all the installed extensions in Chrome.
• Disable all these extensions and restart the browser.
• Now enable them back one by one to figure out which one of them is the culprit. You could also remove extensions that you no longer use.

Option 5 – Run the Chrome Cleanup tool

You might also want to try running the Malware Scanner & Cleanup tool in Chrome. This is a built-in tool that can help you get rid of any unwanted pop-ups, banners, ads, unusual startup pages, toolbars, and malware. Thus, it can help you to resolve the issue in Chrome.

Option 6 – Try to reinstall Chrome

If running the Malware Scanner & Cleanup tool in Chrome didn’t work out for you, you can try reinstalling it. To do so, follow these steps:

• Open the Settings app and go to System > Apps & features.
• From there, look for Chrome and uninstall it from your PC.
• Then go to the official website of Google Chrome and download its latest version and install it.

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

If you are not experienced enough with this kind of task install some automatic solution for this task like DriverFix

3. Check for software issues

   If this error started happening after the installation of new software it is very likely that the application is causing problems. Try uninstalling or disabling the application to see if it will fix the issue. You can also boot Windows in safe mode to see if the error will happen there, if Windows is working fine in safe mode, it is likely that issue is on the software side.

4. Run SFC scan

   Press ⊞ WINDOWS + X and choose Command prompt (admin) In command prompt type in sfc /scannow and press ENTER Wait for the process to be finished and Reboot the system

What is Error 0xc0000142?

Error 0xc0000142 can occur in any of the Windows versions and usually occurs when an application fails to properly initialize.

This error can be critical for a computer as it signifies that the system is unstable. Error 0xc0000142 can cause slow performance in a PC, system freeze, startup and shutdown issues, blue screen and errors in installation.

Solution

Error Causes

Windows/Application Error 0xc0000142 can occur because of a number of reasons.

When a computer is an overload with data, or when system files get broken or missing, this error can occur and will result in startup and shutdown issues as well as the blue screen. Another reason, and one which is quite common, is improper computer maintenance.

This will cause a PC to perform slow, system freezes, and installation errors. This error displays ‘failed to initialize’ on either a Windows error box or the blue screen of death.

Further Information and Manual Repair

Error 0xc0000142 can occur at any time, but there are many ways to resolve it. For instance:

1) Clean the Registry

A corrupted registry is one of the major reasons why this error occurs. The registry is used by Windows to store information and settings on the computer, which is why it has a large database.

This database contains emails, wallpapers, saved passwords and much more in ‘file path references’. These allow Windows to run the common files in your system. A registry cleaner can fix any errors in the registry database.

2) Malware Scan

Viruses can cause certain applications to not function properly. Hence, download a strong antivirus and run a deep scan on your system and remove any potential infections and spyware.

3) Reinstall Applications

Non-critical applications in a computer are those that are installed by the user. If error 0xc0000142 displays in any of your installed programs, then you should reinstall these programs. Often applications have damaged or corrupted files which can slow them down. To resolve this, follow these steps:

• From Start, click on Control Panel
• Go to Add/Remove Programs and uninstall the programs
• Restart your PC and reinstall the program

The third step is not recommended in case the error is caused by cmd.exe

4) Repair Windows

If the error is still on display despite following the previous steps, then you can repair Windows. This process allows Windows to retain all your data and information by simply replacing the program files and settings with fresh ones. This can stop error 0xc0000142 by allowing the programs access to use necessary files smoothly and effectively.

If you cannot resolve the error in any of these steps, then there is another way to do so if you have a computer that runs the Microsoft Internet Security and Acceleration (ISA) Server 2000. Follow these steps in order to resolve it:

• Make sure that in Program Files and Microsoft ISA Server, a Clients folder exists. The ISA Server service will run on this folder
• Confirm that Administrators and SYSTEM have Full Control assigned in the Program Files/Microsoft ISA Server/Clients folder
• Confirm that Msplat.txt file is in the Clients folder. You can copy this file from other ISA Server computers if it is missing
• If the Clients folder is damaged or is missing, or if you can’t copy the Msplat.tct file from another ISA Server computer, then reinstall the ISA Server 2000

What is Backup Error 0x80070002?

Error 0x80070002 shows once you’re done backing up files through the Windows Backup program on a system running Windows 7, you see a notification that pops up with a message that reads something like: “Check your backup results. 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 encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.
