As you know, Windows 10 comes with a pre-packed feature that allows you to rotate the screen at different angles, and to facilitate this feature, there are keyboard shortcuts you can use as well. However, from time to time, no matter how useful this feature is, users still experience a handful of issues. One of which is that they suddenly find their screen rotated or Upside Down even when they didn’t do a thing or adjust the setting. You may have pressed the shortcut on the keyboard by accident or some other program changed the setting on your computer without your permission – whichever the case is, this post will show you what you can do to fix the upside-down screen on your Windows 10 PC using the options laid out below.

Option 1 – Try using hotkeys

• Right-click on an empty part of your Desktop and then select the Graphic options.
• Next, select “Hot Keys” > “Enable”. After verifying that the hotkeys are enabled, you can tap the Ctrl + Alt + Up arrow keys to change your computer screen’s orientation.
• Alternatively, you can also tap the Ctrl + Alt + Right or Left or Down arrow keys to change the direction the other way.

Option 2 – Try using the Graphics Properties

You will probably see the “Graphics Properties” option if you use the Intel HD Graphics every time you click on your Desktop. Note that this option has all the graphics driver properties and helps you in changing the configurations as well as control several options like refresh rate, resolution, color-depth and many more. You have to navigate to these options to see if the orientation is changed in these properties. To do so, follow the steps below.

• Right-click on any empty space on your Desktop and then select Graphics Properties or Intel Graphics Settings.
• After that, select Display from the list of sub-options that appears.
• From there, you will see the rotation of the screen under the “Display settings” option where you have to make sure that the slider is set to “0”.
• Click the Apply button to save the changes made and then click on Exit. The orientation of your screen should automatically change.

Option 3 – Try using the Windows Display Settings

Since the Windows Settings have a section where you can manage the display settings of your computer, you can use them to help control the resolution of your PC’s display without any trouble.

It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist. You could also go over your monitor’s manual if you still have it as it contains details with regards to screen rotation.

Option 5 – Update your Graphics drivers

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.

If you encounter the “Diskpart failed to clear disk attributes” error when you try to change the read-only state of a storage device using the Diskpart application and the request is denied, worry not for this post will give you a couple of fixes to resolve the problem. As you know, Diskpart is used for resolving read-only storage devices by changing their attribute via the command line. So if it is not able to change the attribute of the storage device, then you will most likely encounter an error such as this one. This kind of error is not uncommon and as long as there are no damaged physical attributes, you can resolve it right away. There are tons of reasons why you’re getting this error while using Diskpart, it could be that the storage device has a physical write-protected switch or the disk is hidden or has bad sectors. It could also be because the storage drive might be in RAW format or that you are running the Diskpart application without admin privileges. Whatever the cause may be, here are some options you can try to fix the problem but before you proceed, make sure that you log on to your PC as an administrator.

Option 1 – Check if there is a physical switch on the storage device

There are some USB devices and SD card readers that have a write-protected physical switch that disables all the writable options on the storage device and so if it is turned on, Diskpart won’t be able to change the disk attribute to writable. To check, simply look for the physical switch on both sides of the device and once you found it, make sure that it is toggled off and then plug the storage device back in then try running Diskpart once again.

Option 2 – Modify the WriteProtected key in the Registry Editor

Before you proceed, you have to create a System Restore Point first.

• Tap the Win + R keys to open Run and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to the following path:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the “WriteProtect” registry entry which is located on the left side of the window, and then double click on it.
• Change its value to “0” and click OK to save the changes made and exit the Registry Editor.

Option 3 – Run CHKDSK to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system including the “Diskpart failed to clear disk attributes” error.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 4 – Clear the attributes on RAW

• Tap the Win + S keys then type “diskpart” in the field.
• Click the Diskpart application and if a User Account Control dialog box pops up, click Yes to proceed.
• After opening an elevated Command Prompt, type in the commands listed below and make sure to tap Enter right after you key in one command after the other.
  • list volume
  • select volume ‘n’ (In this command, you have to replace ‘n’ with the volume number of the drive)
  • format fs=fat32 quick (In this command you also have the flexibility to change the format to ‘ntfs’ or ‘exfat’)
• After executing the commands given, unplug the removable storage device and wait for a couple of seconds and then plug it back in.
• Now try any normal write operations and see if the error no longer appears.

Option 5 – Try checking the hardware components

On the other hand, it is also possible that the issue has something to do with a hardware problem and so you need to check the hardware components on your computer to determine that.

If you’re suddenly unable to launch or open Google Chrome or unable to load web pages, then it’s most likely that the files in Chrome have been corrupted or some plugin is taking up a lot of resources which is why you encounter an error message saying, “Google Chrome has stopped working”. And when you try to check the Task Manager, you’ll see that Chrome is really taking up lots of resources, however, when you check the Taskbar, strangely, you will see nothing. If you are currently facing this issue in Chrome on your Windows 10 PC, follow the given options below.

Option 1 – Kill Google Chrome’s process in the Task Manager

If you aren’t able to open Chrome, then maybe its process is running in the background and you don’t see the browser windows. If that’s the case, you may have to force quit the browser and then try to open it again.

• First, right-click on the Taskbar then select the Task Manager. And if the Task Manager is not responding, you can just use the Alt + Ctrl + Del keys and then select the Task Manager.
• After opening the Task Manager, under Processes, look for Google Chrome’s process which would most likely be named “chrome.exe”.
• Right-click on Google Chrome’s process and then select the End task option.
• Now try to open Google Chrome again.

Option 2 – Try checking if your antivirus program is blocking Google Chrome

There are instances when due to false-positive, a security or antivirus program might block Chrome which is why it failed to open properly. Thus, you can just disable the security program temporarily and then check if you can now open Chrome or not.

Option 3 – Delete the User Profile in Chrome

You can also try deleting the User Profile folder in Chrome. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then copy and paste “%USERPROFILE%AppDataLocalGoogleChromeUser Data” and hit Enter.

There are instances when issues on a browser are triggered or caused by some problematic extension. To find out which one of your extensions is causing the problem, disable them all first and then enable them back one by one.

• Click on the three-dotted icon for the menu located at the top-right corner of your screen.
• Then click on the More tools option and go to Extensions.
• From there, you will see a list of all the installed extensions in Chrome.
• Disable all these extensions and restart the browser.
• Now enable them back one by one to figure out which one of them is the culprit. You could also remove extensions that you no longer use.

Option 5 – Run the Chrome Cleanup tool

You might also want to try running the Malware Scanner & Cleanup tool in Chrome. This is a built-in tool that can help you get rid of any unwanted pop-ups, banners, ads, unusual startup pages, toolbars, and malware. Thus, it can help you to resolve the issue in Chrome.

Option 6 – Try to reinstall Chrome

Random freezing in a Windows in the middle of work can be a very frustrating experience and can even cost us the loss of work. From time delays to sometimes complete crashes this behavior is something that every PC user wants to avoid or at least have very little of. In this article, we will cover solutions on what to do and how to fix the random freezing of computers.

1. Run a virus scan on your computer.

   Viruses and other malware can cause freezes and other issues in your computer, run a complete system scan for any kind of viruses and malware and if needed remove them.

2. Uninstall applications that you are not using

   Besides taking your hard drive space some applications can have and require to have some services always running on your computer which can cause some issues, if an application is not needed and it is not used, removing it might solve freezing issues.

3. Increase RAM memory

   Sometimes the problem with freezing is not a software issue, having less RAM memory than the application requires can cause the application not to work properly and it can cause freezing of the entire system since precious RAM can not be allocated to the required application.

4. Run system checker

   Corrupted Windows system files can cause freezing of the entire system, to fix this, start the command prompt in administrator mode and type sfc /scannow

5. Keep running applications to a minimum

   Having too many applications running in the background can drain system resources and can cause system freezes because of lack of memory. Close applications that are running in the background and keep them minimal.

6. Delete files and folders which you are not using

   Having many files and/or folders on the hard drive can cause a lot of system resources to be wasted, from indexing size to less free space for caching. If you have files that you no longer need, removing them will free up space and can increase performance and introduce the stability.

7. Run memory check

   Memory issues could lead to system freezing. When an application needs to write or read to a corrupted memory cluster, freezing will occur since it can not. To check memory bring up run dialog and type in ti mdsched.exe, click on restart now and let the memory test finish.

8. Update all drivers

   Hardware issues can cause freezing of applications and having the latest drivers can make a world of difference. Make sure that you have all device drivers to the latest versions.

9. Optimize Disk drives and check for errors

   Windows 10 has built-in tools to check hard drives for errors and to optimize them, use them in order to see if this issue is causing freezes.

10. Clean your registry

    A Clean registry is a happy registry and Windows is appreciating it. Make sure that you do not have any keys which you do not need in the registry and that long-forgotten application trails are deleted for good.

11. Upgrade SSD firmware

12. Update BIOS

    Like updating SSD firmware can help so it can update Firmware on your BIOS. Make sure that you have the latest firmware version and freezing can go away if that was the issue.

As in previous Windows 10, inside Windows 11 also when you press the ALT + TAB key combination you will get a preview of all running applications along with all Browser tabs so you can go through them and pick the one you want to switch to. Alto, I personally am a big fan of alt-tabbing, I must admit that I am not a big fan of having multiple browsers tabs on screen when I do press key combo. Luckily there is a very easy way to turn this feature off. Turning browsers tabs thumbnails off

1. Press ⊞ WINDOWS + I to open settings
2. Click on System in the sidebar
3. Scroll down and select Multitasking
4. Find Alt + Tab section and click on the drop-down menu
5. Pick Open Windows Only
6. Close settings

Now when you press the ALT + TAB key combination you will still see your browser but only an active tab in it instead of all tabs as different preview thumbnails.

Microsoft just released Windows 11 ISo file, based on the latest Insider Preview Build 22000.132. Inside build, you can try all-new features like clock updated app, snip tool, and everything releases so far via various patches. You can also use Windows 11 ISO file to do a clean install on your computer, but if you go with this option all of your existing files will be deleted. Microsoft says it added the ability to name your PC during the setup experience. You’ll also get to experience the Get Started app that’s designed to help you get going on your new Windows 11 PC (even if it’s not actually a new one).

Download ISO

• Go to the Windows Insider Downloads page. You will need to sign in with a Microsoft account registered with the Insider Program.
• Scroll down to Select Edition and select the build you want to download. You will most likely want the one at the top from the developer channel, as this is where Windows 11 should arrive first. So far, only Windows 10 builds are available. Click confirm.
• Select your preferred language. Not all languages ​​available for Windows are compatible with the Insider program, so you may have to stop depending on where you are from.
• Click the download button and the ISO file will start downloading.
• This is definitely an easier method, but unfortunately, it is not available yet. We will update this article once Windows Insider ISOs are available. Later, once Windows 11 64 bit is available to everyone, you can also download the stable build of Windows 11 iso. Microsoft offers the Media Creation Tool and Upgrade Assistant, which usually do just that. It will be some time before Windows 11 versions of the tools are available, as the operating system is only getting closer to this holiday.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

Anxiety from all these digital threats lurking everywhere? An antivirus program can help put your mind at ease.

What can a virus do to your device?

A virus is malicious software that can affect pretty much any device and does so in a variety of ways. Be it your computer, your phone or your smart lightbulb - as long as there’s access to the internet, malware can get to it.

How exactly does this kind of attack manifest itself? Well, there’s a wide variety of effects ranging from mild to severe. Among other things, they depend on which type of malware attacks your device - a virus, spyware, ransomware, adware or something else.

These are some of the things you can expect to happen:

• Slow performance
• System crashes
• Theft of data and sensitive information
• Connectivity issues
• Constant browser redirects
• Strange messages sent to your contacts 
• Interference with files

It really can be the stuff of nightmares. So, if you want to sleep peacefully knowing that your devices are completely safe, you should definitely consider getting an antivirus.

P.S. don’t let its name fool you - an antivirus does indeed protect your devices against more than just viruses.

What is antivirus software exactly?

Antivirus software is designed to help you battle and ward off malware. Basically, it scans your device to detect any suspicious activity and offers tools to get rid of the culprit. 

At first, antiviruses were developed to fight against viruses only, but nowadays they cover a lot more ground. Here are some of the biggest benefits of getting yourself a powerful defender.

Advantages of antivirus software

1. It fights those pesky ads

Look, constant ads that pop up everywhere aren’t the absolute worst thing that can happen on your computer. If anything, they are annoying, like when you’re trying to sleep but that one fly in your room just won’t stop buzzing.

Now, there’s a free, well-established solution for that - installing an ad blocker. And we’re about a hundred and ten percent sure you’ve already done that on each and every browser you use.

However, “if I can’t see it, it doesn’t exist” isn’t the most ideal approach for your online safety. Ad blockers can’t block everything and they won’t protect you from potential adware. An antivirus on the other hand offers that layer of protection against malware snuck into pop-ups and spammy websites.

2. It protects you from hackers

Hackers don’t target government institutions only. They’ll target regular people too if they have something to gain.

There are different types of hacking, such as phishing e-mails, transmission of malicious programs, credential reuse, denial of service and more. In any case, they take control of your device and hijack your data.

The good thing is that, as threats evolve, antiviruses evolve too and there are tons of quality programs on the market that can keep you secure for an affordable price.

3. It keeps your files and data safe

When malware enters your device, it can target pretty much any file and get access to any and all data.

Installing an antivirus program will make sure that every single file, new or old, is monitored at all times, warning you against threats immediately. That way, you can make sure to react before your other files become infected and data is lost or stolen.

Another great thing for data protection is that the best antivirus software normally comes with a password manager, so no one can use malware to steal your passwords.

4. It blocks all kinds of malware

As we already stated, malicious attacks can be performed in many ways and malware comes in in different shapes an sizes, such as:

• Trojan horse
• Spyware
• Ransomware
• Adware
• Rootkit
• RAT (remote access Trojan)
• Keyloggers
• Worms
• Botnets

Nowadays, antivirus software is designed to fight against all of these types. That’s why more often than not we hear the term 'antivirus' used interchangeably with 'anti-malware,' like in this article.

5. It keeps your children protected

You can’t keep your eyes on your kid every second of the day and you can’t protect them from everything. But at least you can limit their exposure to the threats they can encounter at every corner of the digital world.

An antivirus program will block harmful or suspicious websites and ads, which is great both for you and your children. To take it a step further, though, many such programs come with special parental controls and offer monitoring as well. It’s a great solution for keeping your kids safe online without sounding like the irritating, overbearing, controlling parent who “just doesn’t get it!”

How to pick one

There are definitely lots of different antivirus programs out there, both free and paid. We recommend you look for a paid option, since free ones are unfortunately a lot more susceptible to being compromised through malicious attacks.

Now, there are a few factors to consider when choosing the right software. If you use your PC for basic things then a basic antivirus will suffice. However, the more complex your use and the more sensitive the data you deal with, the stronger it needs to be.

It’s also crucial that you take into account the features it includes. As we already mentioned, some programs have additional security options. For example, depending on the package you select, Bitdefender provides:

• Webcam and mic monitoring
• Parental control
• Firewall
• VPN
• Password management
• Identity theft protection

Some are included in plans and some are separate products, so make sure to check out all the offers.

And don’t worry if you have multiple PCs or you’re looking for protection for your smartphone or tablet as well; Bitdefender has suitable solutions for your needs. Of course, you can also just pick their classic antivirus software if you’re not in need of advanced protection.

Another important point is how regularly the software is updated and enhanced. The more frequent the updates the better, as bugs can make the program more vulnerable. Other things we advise you consider are user-friendliness, impact on performance, reputation (user reviews especially) and, of course, price.

The bottom line

Fact is: anyone can be a malware victim. Don’t let it be you.

You can’t put a price on peace and security, so don’t be reluctant to pay for yours - especially since a lot of options out there are extremely affordable. Is $159.00 a year really too much to pay for cross-platform protection for up to 10 devices? We don’t think so.

Explore your options and protect your files and data before it’s too late.

DOTA2 involves teams of five players each, where each player chooses a “hero” character. Each game has two teams pitted against each other, on opposite sides of a map. Once you start, you and your teammates try to level up by fighting and defeating heroes from other teams as well as non-player characters who exist within the game universe. Once you have a strong enough team, you would then try to attack an opposing team’s base. If you destroy their “ancient,” your team wins. The teamwork and interactivity required to play the game are some of its biggest attractions. You can text and voice chat as part of the Dota 2 gameplay, enabling you and your team to come up with strategies to take over your opponents’ base and fortifications. For this reason, a properly working microphone and headset are important if you are to get the most out of this exciting online game. However, there are many times when you find that there are audio dropouts when you try to speak into your microphone. The question “How do I get my mic to work on Dota 2?” is one of the most commonly asked on gaming forums related to this game. Here are solutions for why this can happen:

1. You are logged in to another computer that is running the STEAM client

   While entirely rare, there are cases where the microphone in Steam is disabled because the same account is active and in use on a different computer. It may not notify you that your account is in use elsewhere. If this is the error, try to log out on other devices and then test it on only one system. If you cannot access the other computer that has access to your account, then change your password. This will automatically disconnect your Steam account from the other computer and let you enjoy voice chat in Dota 2 and other Steam games.

2. Your microphone is not properly set up in Dota 2

   From the main Dota 2 menu, before you start a match, you can set up your microphone for voice chat. At the top, left-hand corner, click the gear icon to open Settings Select the AUDIO tab and ensure that the Sound Device and Speaker Configuration are set to default. On the same tab, activate Voice (Party) and set your Push to Talk shortcut key for your team. Select the appropriate Open Mic Threshold using the slider at the bottom of this tab to get your microphone recorded at a comfortable level.

3. The Windows Audio Enhancements setting is turned on

   If you still cannot get your microphone to work properly, then your problem could be Windows Audio Enhancement. It is possible to get your microphone to work with Dota 2 by disabling these features. Right-click your volume icon on the system tray and select Recording Devices. Choose your active microphone then click its Properties button. On the Microphone Enhancements tab, make sure the checkboxes marked Voice enhancements and Acoustic Echo cancellation is unchecked Reboot your PC and retry using your microphone to chat.

4. Your audio drivers need to be updated

   If you try all of the steps above and still have Dota 2 not recognizing your mic input update mic drivers by going in device manager and choosing update driver.
