So you have just got home from that new computer store with your fancy and all-new mouse, screen, keyboard, etc. You plugged in your new component, Windows detected it, installed drivers for it and it is working like a charm. A few months later down the road and the computer starts little by little to slow down. Plug and play is a great concept, and automatic detection is even greater but how time passes old unused stuff piles in your hard drive and in Windows itself thus slowing down your computer and taxing it more and more as new components and software are added. Old drivers from old components sadly are not removed from Windows itself and over some larger period of time they can pile up and slow down your daily operations on the computer or even cause some problems in it. This guide will teach you how to manually remove old unused device drivers from your Windows so it is fresh and like new again.

Making old devices visible

In order for us to remove old drivers, the first thing we must do is make them visible in our device manager, old drivers are hidden and will not show up, we must make this happen. We do this by pressing WINDOWS + X keys on your keyboard to bring up a hidden menu in Windows. Once the menu appears, click on Command Prompt (admin) Once the command prompt with administrator privileges comes on-screen type in it following string: The device manager will open, go to view > snow hidden devices in order to show unused devices.

Removing old device

Open any category and if there is a device that was once used and still has its drivers in the system it will be shown as faded out. Right-click on the device and click on uninstall device to remove it completely from your system. Please always be careful when removing devices so you do not remove the device which is being used by mistake and always double-check that you are removing something that you used to have on your system. This method will show all hidden devices even ones that are hidden but crucial to the system working properly.

It is no secret that Fortnite is one of the most played games in the world. Epic has done a great job offering it to plenty of other platforms with cross-play feature meaning that you can play with your friends no matter on what platform they are on. But how Fortnite is a piece of software which is constantly updated and maintained it is pretty normal to have some bugs or issues from time to time. One of the before-mentioned issues is a connection issue or unable to connect to game servers. In our article, we will go through common fixes and solutions in order to get you back in-game as fast as possible. Keep on reading.

Check the Epic Games Status page

Check the Epic Games Server Status page to make sure all systems are operational. If the issue you’re experiencing is related to an outage or system-wide issue, you won’t be able to connect to the Epic Games Launcher or Fortnite until it's resolved.

Use a wired connection

Wireless connections are not as stable as wired connections. This means that the signal can be unreliable and result in packet loss, connection problems, or higher latency or ping. Connect directly to your modem or router with an Ethernet cable to eliminate this possibility and have the fastest connection possible.

Using a third-party firewall may prevent you from being able to connect to the Epic Games Launcher, Fortnite, or another Epic Games product. We recommend removing any third party firewalls temporarily to see if this resolves your issue. If it does resolve the problem, make sure to add the following executables as exceptions to your firewall:

Epic Games Launcher

• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\EpicGamesLauncher.exe
• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win32\EpicGamesLauncher.exe

Fortnite

• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_BE.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_EAC.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteLauncher.exe

Contact your firewall manufacturer for instructions on how to add these as exceptions to it as this varies between them.

Unblock your network ports

Network ports allow certain types of data to be successfully sent over a network that is used by our services. If you have any of these blocked, it may result in you being unable to connect to our games or use our services properly. To unblock your ports on your router do the following:

Internal Error 2771 - What is it?

Internal Error 2771 is an internal error code associated with Kaspersky Internet Security and Antivirus software. This error pops up when Kaspersky Internet Security software fails to install on your PC successfully. Installation of the software is interrupted and therefore it ends prematurely. This happens mostly when you try to install a new build on an existing installation. Internal Error 2771 is displayed in one of the following formats:

Internal Error 2771, Sandbox Feature or Internal Error 2771, WholeProduct Feature

Solution

Error Causes

This error may result on your computer screen due to several reasons. Some of the most common underlying causes include:

• A leftover Registry Key
• Bad entries from previous Security Package
• INFCACHE.1 file corrupted
• Conflicts with other security software installed on your system

Further Information and Manual Repair

To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.

Method 1- Remove the Leftover Registry Key

Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal. A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system. This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC.  For this, simply go to the start menu and type Regedit in the search bar. Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete. Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again. Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.

Method 2 - Remove the INFCAHCE.1  Corrupt File

Another reason for the error pop-up may be INFCAHCHE.1 corruption. This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it. To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.

Method 3 - Fix Software Conflict

Security software conflict can also result in internal error 2771 code display. And when this happens, the installation of Kaspersky prematurely ends. Security software conflict may occur if you have Comodo Firewall installed on your PC. A firewall is known to cause issues with Kaspersky software programs. The best way to resolve this issue is to uninstall all security software programs on your PC. Once all security software is removed, then install Kaspersky on your system. If the installation is successfully completed, then reinstall the other software again.

Method 4 - Download Restoro

Error 2771 can also result on your computer screen if traces of the previously installed Kaspersky software still remain in the registry despite the program removal. In such an event it is advisable to download Restoro. This is a cutting-edge and user-friendly PC Repair Tool deployed with an intuitive interface and a powerful registry cleaner. The registry cleaner scans your entire PC in seconds and detects all registry-related problems. It removes all the bad entries, invalid registry keys, traces of previously uninstalled programs, junk files, and cookies that are known for registry corruption. It takes just a few clicks to perform this process. Once all traces are removed, you can install the new version of the Kaspersky Internet Security program on your PC without interruption. Click here to download Restoro and be on your way to resolve Internal Error 2771 on your computer!

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
