The new upgraded Surface Laptop Go 2 is the new iteration of the affordable original Surface Laptop Go aimed to offer good performance at a lower price of under $1000. The new version is not anything vastly different from the original but it comes with much-needed upgrades.

The biggest and main upgrade is the CPU, the Surface Laptop Go 2 is packing now Intel Core i5 1135G7, an Intels 11th generation CPU that should increase battery life. The laptop is also coming with an improved WEB camera and the cheapest one comes now with 128GB of storage instead of 64GB. Price went up from $550 to $599 which is not a big increase considering what was upgraded.

The bad news of new models is that sadly they are still packing only 4GB of RAM, that's really not enough for most applications released in 2022 and the screen is having a relatively low resolution of 1536 X 1024.

Microsoft is still offering all the color variations as in its first offering but added as well a new Sage color that is muted green in tint.

When we look at hardware it seems a little weak but for this price, there is not much competition in the field, and after all this line of models is aimed to provide good performance for an affordable price. If you really need something better you will go with a standard Surface or MAC book instead.

The new laptops are available to pre-order at Best Buy and Microsoft’s online store, and they’ll start shipping on June 7.

5. After you’ve done this, reboot your computer and wait for the next startup to complete.
6. Open Windows Update once again and see if the installation of this pending update is now successful.

Installing the pending Update Manually

Whether you’re experiencing this issue with an integrated webcam driver or with anything else, chances are you’ll be able to circumvent the apparition of the 0x800705b3 error by using the Microsoft Update Catalog to find, download and install the pending update manually.

1. Open your default browser and navigate to the root web page of the Microsoft Update Catalog.
2. Once you’re inside the Microsoft Update Catalog, use the search function (top-right corner of the screen) to search for the update that is failing.
3. After the search is completed and you get the list of results, look for an updated driver version that is compatible with your Windows version and CPU architecture.
4. Once you manage to identify the correct Windows Update, click on the hyperlink associated with the update that you want to install, then click the Download button and wait for the process to complete.
5. After the download is complete, use File Explorer to navigate to the location where you previously downloaded the update.
6. When you get to the correct location, right-click on the .inf file and choose Install from the context menu that just appeared. Note: If you have multiple failing updates with the same 0x800705b3, repeat the instructions above with every Windows Update that you’re having trouble installing.
7. At the end of this operation, reboot your computer and see if the problem is fixed at the next computer startup.

Enabling the Windows Installer Service

The Windows installer service is responsible for installing pending updates that get downloaded by the Windows Update component. If this service is disabled on your configuration, none of the updates waiting to get installed will get completed.

1. Press ⊞ WINDOWS + R to open up a Run dialog box. Inside the text box, type ‘services.msc’ and press ENTER to open up the Services utility.
2. Once you’re inside the Services screen, move over to the right-hand tab of the screen, scroll down through the list of services and locate the Windows Installer service. When you find it, right-click on it and choose Properties from the context menu that just appeared.
3. Once you are inside the Properties screen of the Windows Installer services, access the General tab, click on the Start button to force-start the service. Note: If you can, also change the Startup type to Automatic via the associated drop-down menu. However, depending on your administrator settings, this might not be possible.
4. Restart your computer and wait for the next startup to complete. Once your PC boots back up, attempt to reinstall the driver that was previously triggering the 0x800705b3 error and see if the issue is now fixed.

Performing a Winsock Reset

In case the 0x800705b3 error is related to some kind of network inconsistency (TCP or IP related), you might see Windows Updates failing due to bad data that forces the Windows to abort the installation of new pending updates. In this case, you should proceed by doing a complete Winsock reset procedure to fix the majority of the socket and temporary data-related issues that might cause this behavior. Several affected users have confirmed that this method was the only thing that allowed them to finally fix the Windows Update issue and install pending updates normally. Here are some step-by-step instructions that will walk you through the process of performing Winsock Reset:

1. Open up a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘cmd’, then press CTRL + SHIFT + ENTER to open up an elevated Command Prompt. Accessing an elevated CMD prompt Note: When prompted by the UAC (User Account Control) prompt, click Yes to grant admin access.
2. Inside the elevated CMD prompt, type and taste the following commands in order and press ENTER after each one to effectively reset the TCP and IP data that might be responsible for the apparition of the 0x800705b3 error code:

   nbtstat -R
   nbtstat -RR
   netsh int reset all
   netsh int ip reset
   netsh winsock reset

3. Once every command above is processed successfully, you can go ahead and close the elevated Command Prompt and reboot your computer.
4. After the next startup is complete, repeat the installation of the Windows Update that was previously failing and see if the issue is now fixed.

Performing SFC and DISM Scans

If none of the ‘superficial’ causes have worked in your case, you should start considering some type of system corruption that might affect your computer’s ability to complete pending updates that are currently waiting to be installed. In case you find yourself in this particular scenario, you should run a couple of built-in utilities capable of fixing corrupted instances that might be currently affecting the Windows Update component. Our recommendation is to start with a simple System File Checker scan. An SFC scan will cross-check every Windows File against a local archive that maintains healthy copies. In case corrupted instances are found, this utility will swap the corrupted instance with the healthy equivalent.

Performing an SFC scan

Once the SFC scan is complete, reboot your computer and wait for the next startup to complete. After your computer boots back up, initiate a DISM scan. This utility works differently in the sense that it relies on a sub-component of Windows Update to download healthy copies for the corrupted Windows files that need to be replaced. Because of this, it’s important to make sure that you have a reliable Internet connection before initiating this operation.

Doing a DISM scan

After the DISM scan is complete, reboot your computer one final time and see if the issue is fixed once the next startup is complete.

In case you don’t know, the Title bar comes with the Maximize, Minimize, as well as the Close button. However, there are instances when you might notice that the Title bar, Maximize, Minimize and Close buttons are missing in the File Explorer. This kind of problem might be due to some glitch in the computer, or it could also be caused by some built-in tool or an installed program in your computer. Moreover, there are also other factors that you have to consider such as corruption in the system files as well as errors in the user profile which is generated on a domain network, and so on. There are several suggestions you can check out to fix the problem. You can try to boot your computer in a Clean Boot State to see if a third-party program is the root cause of the problem. You can also try to run built-in tools like System File Checker and the DISM tool. You could also get the video buffer emptied, reset or reinstall the program, or recreate the User Profile.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• You need to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it.

Option 2 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer and see if the System32 folder still pops up at startup or not.

Option 3 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Upgrade problem. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to empty the Vide buffer

These kinds of problems could also be due to bad data in the Video Buffer. Thus, you can try to empty the Video buffer to resolve the problem. All you have to do is tap the Shift + Ctrl + Win key + B keys on your keyboard. After that, leave your computer idle for about 10 seconds until you notice it blink once. Now you try using your computer as usual and see if the glitch is now fixed or not.

Option 5 – Try to reset or reinstall the program

Another thing you can do to fix the issue is to reset or reinstall the program where you encounter the problem. Chances are, you are running the application in the Full-screen mode but you can exit it by simply tapping the Esc or F11 key. However, if nothing changed, then consider resetting or reinstalling the program. Just go to the Windows 10 Settings app and navigate to Apps > Apps & Features. From there, look for the entry of the application you’re having problems with and select it and then click on the Advanced options. After that, click on the Reset button under the Reset section.

Option 6 – Try recreating the User Profile

You might also want to try recreating the User Profile on your computer since some errors in the creation of a User Profile can result in problems like this one. Thus, you have to try deleting the User Profile and then recreate 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.
