How to remove FindYourMaps from Windows

If you are using the Camera app on your Windows 10 computer but encountered an error code 0xa00f429f with an error message that says, “Can’t start your camera”, read on as this post will guide you in fixing this problem. This kind of error in the Camera app could be due to a recent update gone wrong or it could also be due to a corrupted driver. If you are certain that the camera is connected and is properly installed, you can try to check for updated drivers. The error code signifies that the drivers have to be updated. However, that isn’t always the case sometimes as the problem could also have something to do with corruption in the driver. The effective ways to troubleshoot this problem would be trying to reinstall or reset the Windows Camera app, or update, rollback or uninstall some device drivers as well as use the Registry Editor. Before you proceed with the instructions provided below, make sure that you have admin privileges and don’t forget to create a System Restore point.

Option 1 – Try to reset or reinstall the Windows Camera app

As pointed out earlier, you can also reset the Camera app to fix the error. To do so, follow the steps below.

• The first thing you have to do is go to the My Pictures folder under the C: drive of the File Explorer and then delete the Camera Roll folder.
• Once you’re done, right-click on an empty area on your screen and create a new folder and name it “Camera Roll”.
• Then from the Start menu open the Settings app and select System.
• From there, navigate to the Apps and features section.
• Now go to Camera and click on the Advanced Options and click the Reset button.

Option 2 – Try to reinstall the Camera app

If resetting the Camera app didn’t help, you might want to reinstall it by following these steps:

• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option from the menu to open Windows PowerShell as admin.
• Next, type this command to uninstall the Camera app: Get-AppxPackage *camera* | Remove-AppxPackage
• Once done, exit the Windows PowerShell and restart your computer and then try to install the latest version of the Camera app from Microsoft Store.

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the error code 0xa00f429f in the Camera app is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, look for the device drivers which have a yellow exclamation mark.
• Then right-click on each one of them. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.

• Now restart your computer and log back in.
• After that, run the following command:

Dism.exe /online /Cleanup-Image /StartComponentCleanup

• Then scan for updates.

Note: Keep in mind that the remove package command is made for AMD 64-bit machines specifically.

Option 2 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer.

Option 3 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the “We couldn’t install some updates because the PC was turned off” error. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Try to manually install the Windows Updates

Windows Update Error 0x80092004 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes.

The Windows 10 operating system utilizes a variety of measures in order to track your app launches so that it can boost both your start and search results. It can personalize the start menu based on the apps that you use the most on the Start menu as well as the search results. This way, the App Launch Tracking is definitely useful especially when you want to access your favorite and frequently used apps quickly in the Start menu and search results on your Windows 10 computer. On the other hand, Windows 10 provides users with the ability to control their privacy settings in order to protect the privacy of users. Windows 10 users can either opt to enable the app launch tracking to improve the start menu and search menu or opt to disable the app launch tracking in order to prevent the Windows operating system from tracking that you open if you really value your privacy that much.

In case you don’t know, Groove Music is due to retire its OneDrive streaming service this month. Despite that being the case, there is actually a workaround you can try to still continue enjoying music streaming. The app also allows you to play your own local files and if required, you can also modify or tailor the experience with new features – for instance, Groove Music brings an Equalizer to the settings of the app. As the name suggests, the equalizer allows you to tweak frequency responses to your liking. On top of being able to tweak individual bands, the equalizer supports few pre-set settings to enable quick changes. This post will guide you on the process of accessing and using the equalizer in the Groove Music app. To get started, refer to the instructions provided below. Step 1: You need to make sure that you are running the latest version of the Groove Music app or version 10.18011.1211.0 or higher in order to use the equalizer in Groove Music. If needed, you can check the version number from Windows Store. Step 2: Open Windows Store and then click on the ellipses icon and select the Downloads and Updates option. Step 3: Next, search for Groove Music and check its version number. Step 4: Now that you’ve verified the version number of Groove Music, you need to open the equalizer setting. It is enabled by default and to access it, click on the gear icon for Settings and select equalizer under the Playback settings. Step 5: After that, the Equalizer window will pop up. It is where you can configure the equalizer settings using the drop-down menu. Here are the following presets you can choose from:

• Flat
• Treble Boost
• Bass Boost
• Headphones
• Laptop
• Portable speakers
• Home Stereo
• TV
• Car
• Custom

Step 6: Drag the dots upwards or downwards to set your own preferences, as needed. Note: The only downside to this setting is that there is no shortcut available for quick access as you have to navigate through the Settings section manually to access it and change the preset configurations. In addition, the Groove Music app also works on the mobile version of Windows 10.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

What is Mastodon? Mastodon is an open-source microblogging network very similar to Twitter. You can make 500 characters post messages called toot (tweet), share videos or images, and follow other people. But unlike Twitter, Mastodon is decentralized, meaning the entire Mastodon is not run by a single company pulling all strings.

Mastodon can be used directly in your web browser or through a mobile client on a smartphone or tablet. It includes features that seem copied from Twitter-like replies, boosts (retweets), favorites (loves), a timeline view, blocking, and voluntary content warnings that hide sensitive content.

Mastodon also has some great features that Twitter does not have like automated post deletion for the older post of a certain age, requiring approval for follows without restricting your account, and opting out of search engine indexing.

Currently, there are also no ads on Mastodon meaning no ad tracking or ad network surveillance.

How Does Mastodon Work?

Mastodon is a social media network made of nodes called servers or instances each running special software meaning anyone can run their own Mastodon instance (if they have a proper dedicated server). When you have your own instance it can be linked in the federation or remain private, so individuals or companies can have control over individual Mastodon servers.

The software itself is open source based on the social networking protocol ActivityPub which was developed by WWW Consortium.

While using Mastodon, people sign up for accounts with specific instances. Once logged in, you can view a local timeline (of posts from that instance only) or, if the instance is federated with others, see a federated timeline comprised of toots from people in other instances. Mastodon users can send messages to each other using their Mastodon account names that are similar to email addresses in that they feature the server address as well as the user name.
