To make the Windows 10 operating system a lot more user-friendly, Microsoft introduced the Tablet Mode for Windows 10 devices, especially the 2-in-1 devices like Surface Pro and Surface Book. Despite the Tablet Mode’s efficiency, it also encounters some errors from time to time. One of the issues users reported about tablet mode is that they can’t turn off or exit tablet mode. If you are one of these users, read on as this post will guide you in what you can do to fix the issue. To fix the problem with Tablet Mode, there are several suggestions you can check out. You can try to check the full-screen setting, or perform a full shutdown or perform two buttons to restart the Surface devices. You could also disable Tablet Mode via Registry Editor or perform System Restore or change the settings in the System tab or the Action Center.

Option 1 – Try to check the full-screen setting

• Tap the Win + I keys to open the Windows Settings app.
• Then navigate to this path, Personalization > Start.
• Next, scroll down to toggle off the “Use Start Full Screen” option.
• After that, restart your computer and see if the problem is fixed.

Option 2 – Perform a full shutdown

• Open Command Prompt with admin privileges first.
• Next, execute this command to perform a full shutdown: shutdown /s /f /t 0
• The command you entered will shut down your computer and once it’s turned off, wait for a couple of minutes and then turn it back on.

Option 3 – Try to perform a two-button restart on your Surface device

• Tap and hold the power button for about 30 seconds.
• Then release them after 30 seconds.
• After that, tap and hold the volume up + the power button for 20 seconds. This will cause the display to flash a few times but you have to keep those buttons pressed until your Surface device is turned off.
• Wait for a couple of minutes and your Surface will turn back on. This should resolve the problem.

Option 4 – Try to disable the Tablet Mode via Registry Editor

• In the Start Search, type “registry editor” and right-click on the Registry Editor from the results, and then select the Run as administrator option. This will open the Registry Editor with admin privileges.

Microsoft office has two major packages, an online one, and an offline version. The online version of the course is Office 365 that requires a monthly subscription and it is always regularly updated and maintained. Another version is more of a typical old school application, install it and use it, no constant internet connection is required and no monthly subscription is required, buy once and use it. The last version of buying it once and use it was Office 2019 and after two years we are going to receive a new version soon. Microsoft has set its release date for October 5^th of this year and as always it will feature the current latest version of office applications and one-time purchase. The new office will support dark mode and other improvements tied to the new Windows 11 and some specific features tied to Office itself.

Microsoft will soon offer 4 CPU computer specifically aimed at developers and its name is Volterra. The machine as stated will come with 4 processors but the strange thing is that they will be ARM-based instead of x86.

CEO of Microsoft, mister Satya Nadella has introduced the product and Microsoft has released a youtube video promoting it.

https://youtu.be/yICVNta8jMU

The computer system will have Qualcomm's NPU or built-in neural processing unit to use AI's power to help developers write and produce better and faster code. The sad news is that besides processors used there is no other information on other components that will go into this system.

As seen in the video, the computer reminds me a lot of the apple MAC mini with its size and design, and as stated it is made from recycled plastic which in our opinion will bring the price under $1000.

Microsoft has not provided an official price tag for Volterra, but our hope is that it will be more affordable than building your own development PC. Also, there was nothing said about computer availability, we suspect that the selling model will be typical Microsoft one with first models available only in the USA and moving forward slowly opening it to other markets.

Volterra specifications

As previously said nothing except the number of CPUs and their type has been officially said but we managed to get some information about some other specific things not including its inside components.

The unit will have a fan inside of it for cooling purposes and better performance and that is what was officially stated by Microsoft. On the outside, it is known that the computer will have three USB-A ports, a mini DisplayPort, and an ethernet input. All of these will be positioned on the back of the device, on its left side there will be two USB-C ports.

The unit itself will be running on Windows 11 but it was not disclosed anything about the version, we presume since this is a model aimed for professional use that it will come with Windows 11 PRO version.

Currently available tools for ARM

Since this product is aimed at developers logically support for developing software is a must-have and at the time of this writing software that will come and that will run on Volterra is:

• Visual Studio 2022
• Visual Studio Code
• Visual C++
• Modern .NET 6 & JAVA
• Classic .NET
• Windows Terminal
• Windows Subsystem for Android
• Windows Subsystem for Linux

Conclusion

Once MAC studio has been released it showed that specific builds have their audience and can be sold for less of a price than full-fledged custom-made workstations. There is no doubt that Microsoft Volterra will find its audience but will that be enough to have more versions of this compact computer only time will tell.

CyboScan PC Optimizer is promoted as a useful program that helps you clean unnecessary files and registry entries on the Windows Operating System. When installed CyboScan PC Optimizer will automatically scan your computer for issues. Upon reviewing the scan results, it was discovered that most, if not all of these issues were exaggerated, and removing them will not give the promised speed boost. The CyboScan PC Optimizer program appears to scan the Registry for installed anti-virus and anti-spyware shields and may recommend users to install products from partners. This Potentially Unwanted Program comes bundled with other Potentially Unwanted Applications that may harm your Operating System or lead to information compromise.

CyboScan PC Optimizer is also known as MySoftScans PC Cleaner, none of these offer any details about the development company and users will end up paying a fee of up to 99.95USD every 3 months for using the program.

About Potentially Unwanted Applications

You have encountered it – you download a free application, then you discover some unwanted applications on your computer or discover a strange toolbar has been added to your web browser. You did not install them, so how did they appear? These unwanted programs, which are called Potentially Unwanted Programs, or PUPs in short, typically tag along as a software bundle when downloading the application and can result in major problems for computer users. The idea of PUP was actually coined to outline this crapware as something other than malicious software. This is because, the majority of PUPs get into a computer not because they slip via the security holes, for instance, but mainly because the users have installed them themselves – 100 % unintentionally needless to say. Even though a PUP isn’t really malware by definition, it could nevertheless be dangerous software that puts the computer at risk exactly the same way a virus does.

Exactly how do unwanted programs look like?

Unwanted programs can be found in many forms. Typically, they could be found in adware bundlers which are known to utilize aggressive and misleading advertising. The majority of bundlers install many adware applications from several companies, each of which has its own EULA policy. Safebytes Anti-malware completely eliminates this threat and protects your machine against PUP or adware infection. Also, the majority of free programs nowadays come with a few unwanted add-ons; in most cases a web browser toolbar or browser modification such as a homepage hijacker. They may track your online routines, redirect your search results to unsafe websites where viruses can be downloaded and installed, hijack your search page, and slow your browser down to a crawl. PUPs lie inside the gray part of the software spectrum. Some PUPs contain keyloggers, dialers, and other software to gather your individual information which often can lead to identity theft. These are software programs that don’t really do anything useful to you; in addition to taking over space on the hard disk, they also slow down your computer, often alter settings without your permission, and the list of bothersome features goes on and on.

How one can prevent PUPs

• Read carefully before agreeing to the license agreement as it might possess a clause about PUPs. • Always pick the custom if you’re provided a choice between Recommended and Custom Installations – never click Next, Next, Next blindly. • Install reputable antivirus software, just like Safebytes Anti-malware that offers real-time protection against PUPs. • Do not download free applications or shareware unless you actually need it. Disable or remove toolbars and browser extensions you don’t actually need. • Always download software from the original site. The majority of PUPs find their way onto your PC is via download portals, so steer clear of it entirely. Remember that although PUPs can cause damage and hinder the proper functioning of your computer, they can’t enter into your computer without your permission, so be watchful not to give it to them.

Malware Blocking Internet And All Anti-Malware Software? Do This!

Malware can cause all kinds of damage when they invade your system, starting from stealing sensitive details to erasing files on your computer. Some malware variants modify web browser settings by adding a proxy server or modify the computer’s DNS settings. In such cases, you will be unable to visit some or all of the internet sites, and therefore unable to download or install the necessary security software to get rid of the computer virus. If you’re reading this article, odds are you’re stuck with a virus infection that is preventing you to download and/or install the Safebytes Anti-Malware program on your PC. There are a few options you can try to get around with this issue.

Make use of Safe Mode to resolve the issue

Safe Mode is a unique, simplified version of Windows in which just essential services are loaded to stop malware and also other problematic applications from loading. In the event, the malware is set to load automatically when the computer boots, switching to this particular mode may well prevent it from doing so. To start the computer into Safe Mode, hit the “F8” key on your keyboard right before the Windows logo screen shows up; Or after normal Windows boot up, run MSConfig, check “Safe Boot” under Boot tab, and then click Apply. Once you’re in Safe Mode, you can try to download and install your antivirus software application without the hindrance of the malicious software. Right after installation, run the malware scanner to remove most standard infections.

Utilize an alternate internet browser to download antivirus software

Some malware only targets certain browsers. If this is your case, use another internet browser as it may circumvent the virus. If you’re not able to download the antivirus application using Internet Explorer, it means malware may be targeting IE’s vulnerabilities. Here, you should switch to an alternate web browser like Firefox or Chrome to download Safebytes software.

Create a portable antivirus for removing malware

Here’s another solution which is using portable USB anti-malware software that can scan your system for viruses without the need for installation. Abide by these steps to run the anti-virus on the affected computer system. 1) On a virus-free computer, install Safebytes Anti-Malware. 2) Plug the Flash drive into the uninfected computer. 3) Double click on the executable file to run the installation wizard. 4) Choose the USB stick as the location for saving the file. Follow activation instructions. 5) Transfer the thumb drive from the uninfected computer to the infected PC. 6) Run the Safebytes Anti-malware directly from the USB drive by double-clicking the icon. 7) Click on “Scan Now” to run a scan on the infected computer for malware.

Technical Details and Manual Removal (Advanced Users)

If you wish to manually get rid of CyboScan PC Optimizer without the use of an automated tool, it might be possible to do so by removing the application from the Windows Add/Remove Programs menu, or in cases of browser plug-ins, going to the browsers AddOn/Extension manager and removing it. You will likely also want to reset your internet browser. In order to ensure the complete removal, manually check your hard disk and computer registry for all of the following and remove or reset the values accordingly. Having said that, editing the registry is actually a difficult task that only advanced users and professionals should try to fix the problem. Furthermore, certain malware keeps replicating which makes it tough to remove. You’re suggested to do this procedure in Safe Mode.

Same as Windows 10, Windows 11 also keeps track of date and time using an internet time server. But in a case that you need to change the date or time for any kind of reason here is a guide for that process:

1. Press ⊞ WINDOWS + I to open settings
2. Click on Time & Language in Taskbar
3. Inside Time & Language click on Date & Time
4. Turn off Set Time Automatically by clicking on the switch next to it
5. Below find Set the date and time manually and click on Change
6. Inside, Change Date and Time window use the drop-down menu to set desired date and time

Manually cleaning your PC registry may be the worst or best thing you ever decide to do. Registry keys that lie around on your computer, unused, can cause your computer to lag. This can end up in your computer not being able to load the easiest of programs and being slow at loading anything, let alone something that would take up a decent amount of memory. If your computer has slowed to almost an absolute stop, it is most probably the registry’s fault and the only option then is to clean it. You can get programs to do this for you, but they can be riddled with inaccuracies and viruses that could harm your computer even more. This is why some people choose to manually edit their computer. However, this is not without its flaws.

Registry Keys

Registry keys tend to have really long names. These names will be full of numbers and hyphens and will most likely give you no indication of what they do. Even some computer experts find it hard to understand what every computer’s registry keys do. This can make it very hard to see which ones are causing the problem; and if you don’t know what’s causing the problem, then there is no way you will be able to fix it. Some registry keys will be completely menial in what they do but some could be vital to even allow Windows to work on your computer.

Manual Registry Repair

Registry keys can also cause huge problems if you manually delete the wrong one. A lot of registry cleaners have the option to revive a key that they have deleted on you, which means that fixing an error that they made would be easy enough to do. However, when you manually delete registry keys, it will be an awful lot harder to get them back to work again afterward. This can cause your computer many problems and if you delete even one wrong key it is possible your computer will not even start. With the horrid naming system they have as well, it makes it very hard to determine what is important and what is not, which means it is all too likely that you will delete something important. However, those are the risks you have to take when you are cleaning out your registry. A registry cleaner has the same likelihood of messing with your computer and deleting something wrong that you have, so it is the same either way however a registry cleaner will do it with less hassle. But, some people say that if you do it yourself, it’s more likely to be right; that is why they prefer to do it manually and that is alright.

Conclusion

So, if you are manually deleting your registry keys that are unused, you’ll have to use a program that comes with Windows known as ‘regedit.exe’ which is incredibly difficult to use but may just be worth the hassle in the end. So, you don’t really need to put up with a slow computer, but be careful when messing with your registry manually!

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

If you got the Microsoft Store error code 0x80072F30 while trying to open Microsoft Store, then it indicates that the Store fails to connect to the internet or is not able to launch successfully for some reason. It could be that the Windows Update Service has stopped or the Windows Store cache might be corrupted or it could just be due to a poor internet connection. Whichever the cause is, you have to fix this error so that you can use Microsoft Store again and you won’t be getting the following error message every time you open the app:

“Check your connection, Microsoft Store needs to be online, It looks like you are not, error code 0x80072f30.”

The error code 0x80072F30 is related to the Windows Store which prevents it from opening properly. To resolve this problem, you can try fixing the problem with the help of the options given below. Follow each one of them carefully.

Option 1 – Check your internet connection

The first and most obvious thing you can do is to check your internet connection. This may only be a basic tip but it sure works like a charm in most cases. And if you have another internet connection available, you can also try connecting to that and see if you can pull up Microsoft Store or not. 1] Change your internet connection: A basic tip, but sometimes works like a charm. You may want to check if your internet connection has an issue, or you can also try opening a website and see if you can open it and if possible try connecting to a different internet connection and see if the Microsoft Store opens for you. We also suggest you try changing your DNS and see if it helps.

Option 2 – Check the date and time as well as the time zone of your PC

A lot of services and apps rely on the Date, Time, and Time Zone of your PC which is why if they are not configured correctly, a request from the client machine will be rejected from the server and the same thing happens with the Microsoft Store.

• First, go to Settings > Time and Language.
• From there, check if it is set to Automatic or not – if it is, switch the toggle button off to set the Time and Time zone manually.
• Then select the right time zone manually.
• On the other hand, if the Time and Time zone is set manually, you have to switch the toggle button on to set Time and Time zone automatically.
• Restart your PC and afterward try opening Microsoft Store again and check if the problem’s fixed or not.

Option 3 – Run the Network Adapter Troubleshooter

Since Windows 10 is packed with various troubleshooters – one of which is the Network Adapter Troubleshooter – you can use it to troubleshoot the problem. To use it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 4 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 5 – Check the Windows Update Service status

You might also want to check the status of the Windows Update Service since the proper functioning of this app depends on the Windows Update Service. It could be that there is some issue with the service which is why you’re getting the error code 0x80072F30 while trying to open Microsoft Store.

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open Services.
• Next, look for Windows Update Service from the list of available services in Windows.
• Once you see it, check if its status is STOP or Pause and then change the status to Automatic.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your 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.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• 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.
