Fixing Tcpip.sys Blue Screen Error in Windows

As you know, games with good graphics and fast play are definitely resource-intensive and can consume a lot of storage space on your computer. Because of that, they have to be compressed before it gets downloaded to your computer and then unpacked to the hard drive before it gets installed. However, if an error occurs in your computer’s RAM during the installation process or if your hard disk does not have enough memory to handle the process, then you might encounter the isDone.dll error which states:

“An error occurred when unpacking, Unarc.dll returned error code -1, ERROR: archive data corrupted (decompression fails).”

If you encounter the isDone.dll error message on your Windows 10 computer, then read on as this post will show you how you can fix it. This error has something to do with the incomplete installation of PC games or files of larger size. The ISDone.dll error appears due to faulty Unarc.dll file residing in the System32 folder on 32-bit operating systems and the SysWOW64 folder on 64-bit systems. So, if you see this error message, then, it means your computer was not able to read installation archive files.

What is Unarc.dll file?

Unarc.dll is a dynamic link library for Windows. Some applications or games require this file to function properly. So, if it goes missing or, an error occurs when you start a game or an application, you may get various kinds of errors. ISDone.dll error while playing games on PC

Option 1 – Try to reinstall the game

The isDone.dll error could also be caused by the installation of an unknown application. Or it could also be caused by an outdated or corrupted application. In other words, if the game you are trying to install is broken or corrupted, then it’s no wonder why you’re getting the isDone.dll error. To fix this, make sure that you download the latest updated version of the game and then try to install it again and see if the problem is resolved or not.

Option 2 – Try to re-register the .dll file using the Regsvr32 tool

• The first thing you have to do is to locate the DLL file named dll on your computer and rename it to Unarc-bak.dll.
• Next, copy the Unarc.dll file from another well-functioning computer and save it on your desktop.
• After that, move the DLL file you just copied to the System32 folder if you are using a 32-bit operating system, or the SysWOW64 folder if you are using a 64-bit operating system.
• Now you have to register the new DLL file and you can do that using Windows PowerShell.
• Open Windows PowerShell and then execute this command if you have placed the DLL file in the System32 folder: regsvr32 %systemroot%System32unarc.dll
• On the other hand, if you have placed the DLL file in the SysWOW64 folder, then execute this command: regsvr32 %systemroot%SysWOW64unarc.dll

• Restart your computer and check if the problem is now fixed.

Option 3 – Troubleshoot the isDone.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that're preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 5 – Try scanning your computer using Windows Defender

The isDone.dll error might also be infected with malware or virus and to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

When Windows 10 was introduced as an upgrade to Windows 7 and 8, a lot were thrilled because of its new features. One of the most interesting features that this has is the Microsoft Store. Just like in our tablets and smartphones, we can now download our favorite apps from a trusted source. Without the Microsoft store app, you can’t download any applications that you can use on your computer. But what happens if you can’t open your Microsoft Store or you accidentally uninstalled it? The most common error that users encounter when accessing Microsoft Store is the error code 0x80072efd. This error code appears when there is a problem with the internet connection. To resolve this, troubleshoot your modem by doing a simple power cycle. Turn off your modem and wait for a couple of minutes and turn it back on. It should refresh your internet. This works if there is really no problem on the Service provider’s side. Disable your Proxy server, if you are using one to access the internet. To do this, press Windows + R keys on your keyboard. Type “inetcpl.cpl” in the box and go to Connection. Next, click on LAN settings then tick on the box next to Automatically detect settings. Uncheck the box below Proxy Server Among the useful apps that came with the Windows 10 upgrade is PowerShell. It allows you to install and uninstall individual and all apps by using a series of commands. So you don’t have to worry if you can’t find your Microsoft Store or if you accidentally delete it. To access PowerShell, type in the word PowerShell into the search box found beside your Window Icon. Look for PowerShell from the results and right-click on it and hit Run as Administrator.

When you are in the PowerShell window, enter the command below:

Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"

Another option is to download a Windows Update Troubleshooter. After you download it, open the troubleshooter tool and follow the steps. If you saved the file instead of directly opening it, go to the folder where the troubleshooter was saved and double click on the wu.diagcab file to rub the troubleshooter. One of the most interesting error codes that you might encounter when accessing the Microsoft store is error code 1. This particular error code is resolved by changing your PC’s region to the United States. To do this, go to Settings and look for Time & Language. Then go to region and language. Under the Country or region, choose the United States from the dropdown menu then restart your computer. The troubleshooting procedures above are the most common solution to resolve the problem on Microsoft Store issues but there are times that these procedures won’t work. If you are not confident to resolve this through the procedures mentioned in this article, there are so many tools online that you can download to help you out. It also helps to contact Microsoft or consult a technician to ensure that you are doing the correct procedure.

In addition, some malware is capable of replicating or preventing deletion. Doing this in Safe Mode is advised.

The following files, folders, and registry entries are created or modified by MySearchDial

The Windows 10 system allows users to change the default location of the User folders to another drive. This is probably to make sure that the files stay safe in case the system suddenly crashes. However, in some cases, while changing the path to another drive, for instance, the D drive or any folder, the Windows system recognized it as a hard drive as well so even though the files will be saved on that folder, it will appear as a hard drive in the Windows Explorer or look merged with another folder. It could also be that you had dragged and dropped a user folder to another user folder by accident. So if you’re wondering how you can unmerge the User folders, read on as this post will guide you on how exactly you can do that. Take note that even if you try to use the File History to restore the User folders, it still won’t work and you won’t be able to move them back to their previous locations nor restore the folders back to their previous versions and it would only state that they are not available. In the instructions given below, we are using the Downloads folder as an example.

• Step 1: Tap the Win + R keys to open the Run dialog box.
• Step 2: Next, type “Regedit” in the field and hit Enter to open the Registry Editor.
• Step 3: After opening the Registry Editor, navigate to the following registry key:

• Step 4: Then double-click on the multi-string value {374DE290-123F-4565-9164-39C4925E467B} located in the right hand pane. And in the Value Data, copy and paste the following value:

%USERPROFILE%Downloads

• Step 5: Now click OK and close the Registry Editor.

Note: Look close enough and you’ll see that the multi-string values belong to each one of the folders. From there, you have a Desktop, Favorites, Skydrive, Music, Pictures, and many more.

• Step 6: Restart your computer. After that, the operating system will pick up the new folder location during the startup. Here are the values for the other folders:

Music – {1CF1260C-4DD0-4ebb-811F-33C572699FDE} Pictures – {3ADD1653-EB32-4cb0-BBD7-DFA0ABB5ACCA} Videos – {A0953C92-50DC-43bf-BE83-3742FED03C9C} Documents – {A8CDFF1C-4878-43be-B5FD-F8091C1C60D0} Desktop – {B4BFCC3A-DB2C-424C-B029-7FE99A87C641}

• Step 7: Now all you have to do is to change the location correctly. Start by tapping the Win + E keys to open the Windows File Explorer.
• Step 8: After that, right-click on the Downloads folder located in the right-hand pane.
• Step 9: Then click on Properties and go to the Location tab then type “D:\Downloads” in the location box.

Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]

Faraday bag is a new take on security and privacy for people using a lot of electronic devices and credit cards. So what is exactly a Faraday bag?

Faraday bag explained

Faraday bag is designed in the same manner as the Faraday cage which was invented by Michael Faraday, who was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis.

The idea of the Faraday cage is that anything inside a cage that is made of specific grid size is completely isolated from outside current and magnetic fields since the cage itself will pick up everything upon itself. This means that for example, a human could be inside a cage that is struck by lightning and be perfectly safe and fine.

This idea led to the Faraday bag design, which takes this concept and places a wiring pattern inside clothing in order to isolate all magnetic fields from the outside so your devices and cards are completely cut off from any kind of influence and electromagnetic waves. If the pattern and quality of material for the bag are good, you have a fully safe placeholder for your stuff.

Advantages of Faraday bag

The main advantages, of course, are the privacy and safety of mobile phones and credit cards from outside influences and this is why this bag has been designed in the first place. If the bag is designed properly your phone would not be able to be hacked nor accessed from any outside source, GPS tracking will also be disabled and your phone location will not be visible. Credit cards will also be completely safe from any malicious attack via wi-fi signals.

Disadvantages of bag

Well, the disadvantage of using this bag is a very simple one, since your phone is isolated from outside influence that will also mean that you will not be able to take messages or calls on it while it is in the bag. Notifications from the internet would also be disabled so it is security vs usability deal.

If you encounter the “We couldn’t install some updates because the PC was turned off” while trying to run Windows Update on your Windows 10 computer, then read on as this post will give you a couple of suggestions you can use as a reference to fix this error.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list.
