If you like to schedule different tasks on your Windows 10 computer and automate them, then you would find the Windows Task Scheduler very useful. It is commonly used by a lot of users to schedule various tasks like scheduling periodic execution of scripts and some programs to make sure that the intended tasks are automatically carried out. Apart from being a preinstalled application, the Task Scheduler is already available on your computer. However, there are times when you might encounter some errors while using it. One of these errors is error 0xFFFD0000. You can encounter this error while executing some PowerShell scripts. It can occur to any tasks as well especially to the ones that have a file executed using a particular program. And just like the PowerShell script, files also use PowerShell to be executed.

Step 2: After opening Task Scheduler, right-click on the task that’s giving you the error and then click on Properties. Step 3: After that, navigate to the Actions tab in the new mini window that appears. Step 4: From there, select the action for the task and click on the Edit button which will open another mini window. Step 5: Next, make sure that the path to the executing program is properly typed inside the field of Program/script. Note that it should be set to the executable file for that particular program. For instance, you have to set it to “C:WindowsSystem32WindowsPowerShellv1.0powershell.exe” for the Windows PowerShell program. Step 6: You can also utilize the Browse button and navigate through Windows Explorer to locate that particular executable file for the program. Step 7: Now make sure to use the file argument in the Add arguments field followed by the path of the file to be executed. It should look like this:

-file "C:/Users/Ayush/Desktop/Powershell Script Sample.ps1"

Step 8: Once done, click on OK to save the changes made and see if the task is still giving you an error or not. On the other hand, if you are still getting the same error, you can try to repair the Task Scheduler by deleting corrupted tasks. Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:

• Tap the Win + R keys to open the dialog box for Run.
• Next, type in regedit and click on OK or tap Enter to open the Registry Editor.
• Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree

Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take a note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.

• Right-click on the task name and then delete it.
• After that, delete the very same GUID which you have copied earlier from these folders:
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks

Note: You might not see the same GUID from these folders but if you see it, delete it right away.

• Next, navigate to this location: C:WindowsSystem32Tasks
• Delete the very same tasks you just deleted from the Registry Editor.
• Restart your PC and check if the Task Scheduler is back to its normal state or not.

Many users would probably agree that the Windows Media Player, in most cases, is a lot better than the Groove. Although it is understandable why the Groove Music app was created, it may be time for Microsoft to bring its focus back on Windows Media Player. Even more, so that some users are experiencing an issue where they were not able to play their playlist in the Windows Media Player on their Windows 10 PCs. One particular user claimed that when he removed his music from the C drive and transferred them to the C drive for some reason he didn’t state. Right after he did that, any attempts to play songs in the Windows Media Player just don’t seem to work. Transferring music to a different location shouldn’t cause any issue but for some unknown reason, it did. According to security experts, the reason why the Windows Media Player didn’t play the playlist is that it still believes that the songs are still located in the C drive when they’re really not. So the question here is, how can you get the Windows Media Player to recognize the exact and correct location of the songs? Worry not, for this post will show you how exactly you can do that. Carefully follow each one of the instructions given below to fix the Windows Media Player issue.

Option 1 – Try running the WMP Troubleshooters

In case there are any issues with the Windows Media Player, you can always count on the WMP Troubleshooters to fix the problem for you. These built-in troubleshooters, namely, Windows Media Player Library and Windows Media Player DVD Troubleshooters can help you fix the problem, so run them both and see if you can now play those songs or not.

Option 2 – Try rebuilding the Windows Media Player Database

If the first option didn’t work for you, you might have to rebuild the Windows Media Player database. You can do this by following the steps below.

• Tap the Win + R keys at the same time to open the Run dialog box.
• After that, copy and paste this command in the field: %userprofile%Local SettingsApplication DataMicrosoftMedia Player
• Once you’ve pasted the command, hit Enter then you will see a new File Explorer which is the folder for the Media Player. You will have to delete every item in this folder, except for the folders. Meaning to say, you must only delete the individual contents inside but not the folders.
• Now launch the Windows Media Player again and watch as it rebuilds the music library automatically.

Having the latest applications is often preferred for most users but sometimes we have some old applications which have not been updated or simply we just want to run oldie on our computer because it does everything we need and we do not want to upgrade in order to save some money. The issue is presented sometimes when we try to run an old application in Windows 10 and some components are missing in Windows itself or the application is simply coded in a way to work on older Windows versions. If by any chance you have this issue then this guide is for you since we are going to show you how to run old applications in Windows 10. This guide is made in a way to takes into account that the application itself is completely installed on your Windows 10 machine if you can not even install the application you will need to search solution for that particular application since that can not really be generalized and pinpointed issue, every application is different.

Running old applications using the compatibility option

All of that being said, let's start that old app you have. First thing is to locate an executable file or shortcut of the desired application. Once it is located, right-click on it to bring up the menu, and all the way to the bottom you will find properties. Left-click on properties. The application settings screen will open, in upper tabs locate Compatibility and left-click on it. After the click, you will find yourself in application compatibility settings. In this window, you will face different options to run the chosen application in various modes in order to make it run. How settings are self-explanatory and different applications will need different settings sadly we can not cover them all but your safest bet is to run them in an environment where they have worked. For example, if the application was working fine in Windows XP and required administrator privileges, check Run this program as an administrator and Run this program in compatibility mode for Windows XP.

Without any fanfare, news, or information Bethesda has released a completely free upgrade for legendary Quake 1. Free upgrade is automatically applied to all users who possess the original game and it has already been rolled out.

What has changed for good?

New textures, effects, and resolutions are one thing that will come first into your focus when you start the game. From the moment game is started it feels and looks like a game you remember from a long time ago. Models are also upgraded with a higher polygon count. Another thing that will hit you right away is the legendary OST by Trent Reznor in its full glory. If you have the original Quake and played it you will know that OST was missing from the Steam release and having it fully back is a great feature. I would argue that placing just OST alone in the steam release is enough for people to play it again since it adds so much atmosphere. Deathmatch and other multiplayer goodies are all here as well and there is a completely free new episode in the game with several levels. Yes, you get a free Quake upgrade in HD with an extra episode completely free.

The bad side of Quake coin

So this might come as a purist or obsessive nit-picking but there were two things that I, personally am not a fan of and have noticed during my gameplay. Please know that this is personal preference and by no other chance reflects the quality of the game itself but I just had to talk about it. Quake remake is made in a new engine and as such dynamic and gunplay feel different from the original, granted they have done the best they could to replicate the authentic feeling of the original game but there are parts of the game where I have felt that simply put, it feels different. Another thing is also tied to technology and the overall game is somewhat a little brighter and in some areas little softer in dark areas. Like I said this is purely personal preference and might come as nitpicking but I preferred the darker and grittier look of the original game. Darkplaces, the free custom-made upgrade did this in my opinion better.

Today most people have Facebook accounts where they keep in touch with friends and family. But large Facebook network of users is also very interesting to another party as well, hackers. There are many ways hackers can steal your data via direct hacks, trickery, and social engineering in order to get your credentials, emails, and many other things using them to wreak further havoc. Once a hacker has needed information it is very difficult to minimize impact and all of your information could be compromised from a list of friends to credit card numbers. Keep on reading to learn how can you protect yourself against these attacks and learn about common practices that hackers use in order to steal your data.

Stealing Facebook data via email

A couple of years ago there was a lot of talk about not opening suspicious emails. Well, it still holds today. The difference is that today’s fake emails have become very difficult to differentiate from official ones since hackers put the effort into creating them copying fonts and layout, making them identical to original ones. So if emails look and feel like original ones how do you know if it is fake? Very simple, you do not click anything in it. If Facebook or for that matter any company wants to contact you they will do via their platform. Clicking inside a hacker's email will lead you probably to a fake Facebook website replica where you will have to type in your username and password providing an attacker with your login credentials, etc. If you receive this kind of mail where there are threats about terminating an account, missing payments, etc. it is always the best thing to go directly to Facebook and see if you have any kind of notifications there. Do not trust any emails that ask for account information, request money, or threaten to suspend your account.

Phishing attacks

As stated previously if you click on the link inside fake mail it will probably lead you to a website replica of the original. Although hackers can pretty much copy all things from an original website like layout, fonts, colors, etc. There is one thing that he cannot, web address. Take a good look into your browser address bar to see if there is a typo or anything strange in the address of a website. Also, make sure to check for the secure icon in the web address before signing in.

Fake Facebook buttons

If by any chance and for whatever reason, you end up on a fake Facebook site be vary careful about like and other buttons since buttons themselves behave and act like links inside your browser. IF when you click on like you get a prompt to sign in, it is almost 100% that you ended up on a phishing fake website.

Password brute force attack

Having complex and long passwords is a must. If your Facebook password is 12345 there is a very high chance that if a hacker wants he can easily guess it via trying out the most used and simple passwords via simple guessing. To avoid being hacked just for having poor passwords try to think of something longer, combine letters and numerical characters, place special characters inside it or just simply as the best solution use a password manager and create passwords with it.

Password grab outside Facebook

If you use the same password for multiple accounts which is a big no-no and you should not do it then hackers can use passwords from other services and login into your Facebook in order to steal data. Avoid these situations by having different passwords for different accounts or use a password manager to keep everything in order.

Hacking via key logger

Some time ago we have made an article which explained in detail everything you need to know about key loggers here: https://errortools.com/windows/how-to-know-if-you-have-keylogger-in-windows/ Anyway, this is a more advanced hacking technique in order for hackers to steal your data and it includes placing malicious applications into your system that records your keystrokes and sends them directly to hackers. Since this is an application best protection against this type of attack is to have a security suite installed and active on your PC or device you use to go to Facebook.

Connecting and surfing on an unsecured network

Using no password and unsecured WI FI or any other type of network is risky at least. You can have all protection installed on your device and have a strong password but hackers also logged in to the same network can track all outgoing stuff going through mentioned network leaving you again exposed to attacks. It is better to connect to your mobile operator network than on free WI FI, at least there is some level of security in your operator network while free WI FI is completely unsecured. Getting a virtual private network or VPN is also one thing you could think about for protection since almost all VPN services will encrypt your data thus providing you with a security layer even on unsecured Wi-FI.

Conclusion

Hacking and stealing have come a long way from their infant stages and in today’s world when we use a lot of gadgets and have plenty of online presence taking some steps for security is a must. I hope that you have found anything here informational and helpful so you can avoid getting your data compromised.

Thus, you have to disable the QUIC protocol in order to resolve the error. How? Simply follow the steps below.

• Open your Google Chrome browser.
• Now type in “chrome://flags/” in the address bar and hit Enter.
• After that, look for the Experimental QUIC protocol which should be set by default.
• Then expand the drop-down menu and select Disable.
• Restart Google Chrome and see if the error is fixed or not.

Option 2 – Disable VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server to fix the ERR_QUIC_PROTOCOL_ERROR in Chrome. Refer to these steps to do so:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.
