SmartScreen is a cloud-based anti-phishing and anti-malware component that’s come packed in all Windows 8 (8.1) and Windows 10 versions. This security component is also used in several browsers and programs like Internet Explorer, Microsoft Edge and Outlook.com. Although this program is quite useful, there’ve been reports that SmartScreen is apparently blocking Microsoft’s own apps from opening. According to some users, they only get the “Windows SmartScreen can’t be reached right now” error message every time they try to open apps from the built-in Windows suite like Photos, Mail, Alarms, Maps, etc. Whenever Windows SmartScreen is either down or unreachable on an end-user PC, your computer won’t be able to download anything in both official and unofficial channels. This error might be due to a corrupted Windows account, or it could be that SmartScreen is disabled from the Windows Defender Security Center or it might be down due to an MS issue. In addition, the error might also be caused by a proxy entry.

Option 1 – Make sure that SmartScreen is enabled

Before anything else, the first thing you must do is to check if SmartScreen is even enabled as it might be the reason why you’re getting the error. You can verify this by simply going to the Windows Defender Security Center. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:windowsdefender” in the field and hit Enter to open the Windows Defender Security Center.
• After that, click on the Open Windows Defender Security Center button located under Windows Security.
• Then click on App & browser control.
• From there, make sure that the Check apps and files toggle is set to Warn and then check the same thing for Microsoft Edge and SmartScreen for Microsoft Store apps.
• If it turns out that SmartScreen is indeed disabled, you have to restart your computer after making some changes and then check if the issue is fixed upon the next startup.

Option 2 – Check if SmartScreen is down for maintenance

Another possible reason why SmartScreen is not working is that it might be scheduled for maintenance. When SmartScreen is scheduled for maintenance, it will become unreachable for a lot of users at the same time and so before you go over unnecessary troubleshooting steps, you need to verify if SmartScreen is down for maintenance or not.

Option 3 – Try to disable the proxy server

If applicable, you can try to disable the proxy server to fix SmartScreen. There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. In some instances, certain proxy servers can interfere with the SmartScreen component and cause it to become unusable. However, if you are not using a proxy server, just skip this option and proceed to the next one, otherwise, follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:network-proxy” in the field and hit Enter to open the Proxy tab under Settings.
• After that, scroll down to the Manual proxy setup and make sure that the toggle button of the “Use a proxy server” option is turned off.
• Now restart your PC and check if the problem is fixed upon the next startup.

Option 4 – Try to create a new Windows user account

There are some users who were able to fix the problem by simply creating a new Windows user account. Although this solution will make you lose a couple of settings enforced through your user account, it’s actually effective in circumventing the “Windows SmartScreen can’t be reached right now” error. To create a new Windows user account, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• And then type “ms-settings:otherusers” in the field and hit Enter to open the Family & other people tab under the Accounts menu.
• After that, click on the “Add someone else to this PC” option and then click on “I don’t have this person’s sign-in information.
• Next, insert the user credentials like emails, password, birth date, etc., and then click Next. Take note that if you want to create a new local user account, just click on Add a user without a Microsoft account.
• After you’re done creating the new Windows user account, click the start icon and then click the account icon and choose to Sign out.
• After you’re logged in, check if SmartScreen now works properly or not.

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.

Error Code 0xC004C770 – What is it?

If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.

Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.

Solution

Error Causes

Error Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.

Further Information and Manual Repair

There are two basic methods for addressing the issues associated with Error Code 0xC004C770. These methods can easily be implemented by anyone who is comfortable interacting with the Windows Store from their computer, which makes the resolution of this particular error code fairly simple and straightforward.

If you are unable to complete the steps below or Error Code 0xC004C770 has not been resolved after following the guides below, contact a Windows technician who is familiar with the Windows 10 activation process to assist you in the process. You can also get in touch with the Windows technical support team to assist you in the process if needed.

Method One: Purchase A New Product Key from Windows

If you have already used the product key on another computer or have used it on the maximum number of allowed devices, you may need to purchase an additional product key for the computer with Error Code 0xC004C770. Product keys can be purchased physically from a retailer that sells Windows 10 software licenses or purchased directly from the Windows store.

To purchase a new product key directly from the Windows Store, follow the steps below:

• Step One: Select the Windows start button at the bottom of your toolbar. Click on “Settings,” then select the option for “Update and Security.”
• Step Two: Click on the “Activation” option.

If you are unable to see the “Go to Store” option when you reach the “Activation” page, you may not be set as an administrator of your machine. In this case, get in touch with the support personnel from your company to complete the purchase, installation, and activation process on your computer.

Method Two: Attempt to Finish Activation via Phone

For users who have changed out parts of their computer’s hardware, like putting in a new motherboard or activating a new hard drive, you may have more success if you attempt activation through a phone.

In order to activate your copy of Windows 10 from your phone, follow the steps below:

• Step One: On your mobile device, open up the search box from the taskbar.
• Step Two: In the search box, enter the phrase “SLUI 04.”
• Step Three: Select the “SLUI 04” option that appears.

There are many times when you have to change the ownership of a folder or a file so that other users can use them as well or if you want to transfer files to them, or an old account has been removed and all the files need to be assigned to a new user. Windows 10 keeps all these files locked under the account by default which created a folder or file. So unless a user is an admin or if the file belongs to that particular user, other users won’t be able to access or edit the file. So if you want to change the ownership of a folder or a file, then you’ve come to the right place as this post will guide you on how exactly you can do that.

To get started, make sure to follow the instructions provided below carefully.

Step 1: First, you need to open File Explorer by tapping the Win + E keys. Once you’ve opened it, navigate to the folder or file that you want to change the ownership. Step 2: Right-click on the folder or file and click on Properties and then go to the Security tab. Step 3: From there, click on the Advanced button located at the bottom right part of the window to open the Advanced Security Settings of the folder or file. Step 4: As you can see, the current owner will be listed with the Change link available next to the “Owner” label. Now click on this link to open the Select User or Group window. Step 5: After that, click on the Advanced button once again and click on the “Find Now” button to see the list of all the users as well as groups that are available in the computer. Step 6: Then select the user you want to give ownership to and click on the OK button and then click the OK button once more to save the changes made. Step 7: This will take you back to the Advanced Security Settings window but this time, the owner will be changed to whoever user you’ve selected. But you’re not done yet as you still have to check two additional options to help you completely transfer the ownership of the sub-folders as well as the files. You have to check the checkbox of the following options:

• Replace owner on sub-containers and objects
• Replace all child permission entries with inheritable permission entries from the object.

Step 8: After that, you need to click the Apply and OK buttons to confirm and save the changes made. This will completely transfer the ownership of the file. However, there is still one last thing you have to do – you have to go back to the Advanced Security Settings window to remove the access of any other user on the folder or file. Once you’re there, remove the existing user to make sure that the only assigned user has the access to the folder or file.
