As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:

• 0 – Incognito mode is enabled by default
• 1 – Incognito mode is disabled
• 2 – Chrome is forced to always open in Incognito mode

You have the option to choose to configure the Network to Private or Public when you set it on Windows 10 PC. On the other hand, if the option to change the Network from Public to Private goes missing in Windows Settings then this post will surely help. You can find this setting under Settings > Network and Internet > Ethernet and appears when you click on it. If you are not able to see the option to change the network profile, then you either can’t open the settings, or the option to change it has been disabled. To resolve this issue, you can either use the Registry Editor or Windows PowerShell. Refer to the options given below for more details.

Option 1 – Change the Network Profile via Registry Editor

Changing the Network Profile can be done using the Registry Editor. But before you proceed, make sure that you create a System Restore Point first just in case. Refer to the steps below to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetworkListProfiles
• Now expand the Profiles key folder located in the left pane to see one or more folders.
• Next, expand each one of these folders and look for the “Description” sub-key which should match the name of your network.
• After you find the Description sub-key, look for another sub-key named “Category” and double click on it to open it.
• Now change its value from “0” to “1” to change the Network Profile from Public to Private.

Option 2 – Change the Network Profile via Windows PowerShell

Aside from the Windows Registry, you can also use Windows PowerShell in changing the Network Profile from Public to Private and so on. Take note that you have to use PowerShell with admin privileges. Just refer to the steps below to do so.

• Tap the Win + X keys and then select the “PowerShell (Admin)” option.
• Next, click on Yes if the User Account Control prompt appears.
• After that, execute the commands listed below. Hit Enter right after you key in each one of them.
  • Get-NetConnectionProfile
  • Set-NetConnectionProfile -InterfaceIndex <index number> -NetworkCategory Private

Note: Since every Network Profile has an index number, you can check the label “Name” to identify the network that you want to change.

If you got an error code of 0x80072EE2 while trying to download a Windows 10 update then it could be that something is blocking the Windows Update service on your Windows 10 PC and is preventing it from connecting to the Microsoft server. In addition, the error code 0x80072EE2 also indicates “ERROR_INTERNET_TIMEOUT” and together with this message, you might also see a message as Windows Update encountered an unknown error or you might also find it hard to search for new updates.

• Log onto your PC as an 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.)
• After that, try to install the Windows app again.

Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application on your computer. You need to look for the culprit and uninstall it once you found it.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error code 0x80072EE2. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

If you suddenly encountered the PDC WATCHDOG TIMEOUT BSOD Blue Screen stop error with a bug check value of 0x0000014F, then it’s probably due to a system component that has failed to respond with the allocated period which prevents the system from exiting connected standby. This kind of Blue Screen error could be caused by both hardware and software components. To fix this Stop error, here are some possible fixes you can try that might help but before you proceed, make sure that you create a System Restore point first and boot your computer into Safe Mode with Networking.

Option 1 – Try to rollback, update or disable drivers

The next thing you can do to fix the PDC_WATCHDOG_TIMEOUT Stop error 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 driver named “IDE ATA/ATAPI controllers” and expand it.
• Then look for the SATA AHCI Controller entry and right-click on it. 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.
• Next, follow the screen option to update or uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall them.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the PDC_WATCHDOG_TIMEOUT Blue Screen error.

Option 3 – Try running the Memory Diagnostic Tool

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the PDC_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 5 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PDC_WATCHDOG_TIMEOUT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.

Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.

So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.

SONY PLAYSTATION VR

If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.

While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.

VALVE Index

Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.

The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.

However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.

META QUEST 2

Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.

Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.

Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.

Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.

What Is 0x00000050 Stop Error?

While running your Windows 7/Windows Server 2008 R2, your system suddenly stops responding out of complete randomness and you see an error message popping up which says something like this:

0x00000050 (parameter1, parameter2, parameter3, parameter4)

Solution

Error Causes

The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.

However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.

This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.

If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.

Further Information and Manual Repair

In order to fix this issue, you should try booting your computer to the “Last Known-Good Configuration” as listed during startup.

For this you have to follow the below-mentioned steps:

1. Start your system.
2. When you see the message which says “For Troubleshooting And Advanced Startup Options For Windows, Press F8” hit F8 and proceed.
3. Use the up and down arrow keys to highlight “Last Known-Good Configuration” and hit enter (This method will only work if your system boot was not successfully carried out ever since you made any specific changes).
4. When you are starting the computer, press F12 and proceed with the PSA/32 Bit Diagnostics.
5. Do the following so that a clean boot can be performed:

• Go to the Start menu when the Windows 7 desktop shows up.
• On the search bar, type “msconfig” and hit search.
• Disable all the applications which are listed on the “Startup” tab.
• Now head over to the “Services” tab and mark the option which reads "Hide all Microsoft Service".
• Select the “Disable All Services” option.
• Apply the changes by clicking on “Apply” then restart your PC. You should now check the performance of your computer. If you don’t see a BSOD then you start re-enabling all the Services and Startup applications one by one until you finally figure out which one is causing the BSOD to appear.

6. Update your Windows with “Windows Updates”.

In Installing or upgrading your Windows 10, there really is no guarantee that everything will go smoothly as there are times you encounter errors like the “ We couldn’t install Windows 10, 0x8007002C - 0x400D ” error message among other Windows update/upgrade errors. When you encounter this particular error message you will the following message on your screen:

 “We’ve set your PC back to the way it was right before you started installing Windows 10. 0x8007002C-0x400D The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation”

This kind of Windows upgrade error indicates that some of the files needed for the installation are locked out for some reason and that Windows was not able to migrate them to a new version. It could be that your computer does not have sufficient space for those files. Thus, no matter how many times you try to upgrade your computer, you always end up going back to the previous version of Windows. To fix the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error, here are some suggestions that might help:

Option 1 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 2 – Perform a Disk Cleanup to free up disk space

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error instead so you need to perform a Disk Cleanup in order to fix the problem.

• In the Cortana Search box, type “disk cleanup” and click on the related search result.
• Then select the disk you want to clean and click OK.
• Wait for the process to be completed and then restart your PC and try to install the Windows upgrade again.

Option 3 – Get rid of any file protection software

The Windows setup migrates the folder from one version to another during the upgrade. However, if some of your folders, if not all, are protected using some file protection software, then Windows won’t succeed in moving the folder and you will encounter this Windows upgrade error instead. Thus, you need to unlock all those protected files or better yet uninstall the file protection software after you remove the locked files. After that, try installing the upgrade again.

Option 4 – Rename the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• 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 stop bits rename c:windowsSoftwareDistribution SoftwareDistribution.bak

• After entering these commands, it will stop the Windows Update Service, the Background Intelligent Transfer Service, and rename the SoftwareDistribution folder.
• Next, got 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.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 5 – Run the DISM tool

As mentioned, the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error might also be caused by corrupted files in the computer. Thus, you can try using the DISM tool to repair them. Running the DISM tool can repair the Windows System Image and Windows Component Store in Windows 10.

• Open the Command Prompt as admin.
• Then type in this command: DISM /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 6 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve this particular Windows upgrade 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.

Option 7 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors including the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error.

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.
