Fixing the Java Error Code 1603 in Windows 10

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.

If you have suddenly run into a problem when trying to connect or pair your Bluetooth keyboard with your Windows 10 computer, read on as this post will guide you on how exactly you can resolve the problem. This kind of problem typically occurs when you’ve disabled the Bluetooth option. However, this option is already enabled and you still encountered the same error message saying, “Check the PIN and try connecting again”, then you need to troubleshoot the problem further. In most cases, this kind of issue can be fixed when you restart your computer and go to the Windows Settings and select the “Add Bluetooth or other devices” option and then put the keyboard into pairing mode. And when the keyboard appears in the “Add a device” dialog box, just select it. On the other hand, if your Bluetooth keyboard won’t get connected to your Windows 10 computer and you encounter an error that says, “Can’t pair Bluetooth keyboard, Check the PIN and try connecting again”, then you need to check out the options provided below but before you do so, make sure that you create a System Restore point first as some of the troubleshooting options provided involves the Windows Registry.

Option 1 – Try to use the Device Pairing Wizard

The Device Pairing Wizard is the one that allows your computer to look for any new devices and display them underneath it. All you have to do to use this wizard is to follow its instructions to connect your Bluetooth device to Windows 10. To get started, follow these steps:

• First, tap the Win + R keys to launch the Run utility and type “devicepairingwizard” in the field, and then hit Enter to run the Device Pairing Wizard.
• After that, wait for a couple of seconds until the devices appear. Once they do, select the Bluetooth device you wish to add.
• A new screen with a passcode should appear instantly. You need to take note of the given passcode and type them on your Bluetooth keyboard.
• Once done, tap Enter. This should help in pairing your computer to your Bluetooth keyboard.

Option 2 – Try to use the Registry Editor

The next thing you can do to resolve the pairing issue with your Bluetooth keyboard is to use the Registry Editor by following these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_USERS/.DEFAULT/Software/Microsoft/Windows/CurrentVersion/Bluetooth/ExceptionDB
• From there, look for the folder named “Addrs” and expand it. If you see any folders or keys under it, select them and delete them. These keys represent the MAC address of your Bluetooth devices.
• Once you’re done, restart your computer and try to pair your Bluetooth keyboard once more.

Option 3 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the Bluetooth Troubleshooter.

• Open the Windows 10 Settings.
• Then go to Update & Security > Troubleshoot.
• You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.
• Now follow the next screen options.

Option 4 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since you have trouble pairing your Bluetooth keyboard, you can update, rollback, or uninstall the Bluetooth drivers. How? Follow the steps below.

• Tap the Win + X keys to open the Device Manager.
• Next, look for the Bluetooth device and right-click on it.
• Select the option “Update driver”.
• After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.

Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it.

Many users would probably agree that the Windows Media Player, in most cases, is a lot better than the Groove. Although it is understandable why the Groove Music app was created, it may be time for Microsoft to bring its focus back on Windows Media Player. Even more, so that some users are experiencing an issue where they were not able to play their playlist in the Windows Media Player on their Windows 10 PCs. One particular user claimed that when he removed his music from the C drive and transferred them to the C drive for some reason he didn’t state. Right after he did that, any attempts to play songs in the Windows Media Player just don’t seem to work. Transferring music to a different location shouldn’t cause any issue but for some unknown reason, it did. According to security experts, the reason why the Windows Media Player didn’t play the playlist is that it still believes that the songs are still located in the C drive when they’re really not. So the question here is, how can you get the Windows Media Player to recognize the exact and correct location of the songs? Worry not, for this post will show you how exactly you can do that. Carefully follow each one of the instructions given below to fix the Windows Media Player issue.

Option 1 – Try running the WMP Troubleshooters

In case there are any issues with the Windows Media Player, you can always count on the WMP Troubleshooters to fix the problem for you. These built-in troubleshooters, namely, Windows Media Player Library and Windows Media Player DVD Troubleshooters can help you fix the problem, so run them both and see if you can now play those songs or not.

Option 2 – Try rebuilding the Windows Media Player Database

If the first option didn’t work for you, you might have to rebuild the Windows Media Player database. You can do this by following the steps below.

• Tap the Win + R keys at the same time to open the Run dialog box.
• After that, copy and paste this command in the field: %userprofile%Local SettingsApplication DataMicrosoftMedia Player
• Once you’ve pasted the command, hit Enter then you will see a new File Explorer which is the folder for the Media Player. You will have to delete every item in this folder, except for the folders. Meaning to say, you must only delete the individual contents inside but not the folders.
• Now launch the Windows Media Player again and watch as it rebuilds the music library automatically.

TPM or Trusted Platform Module version 2.0 is a must-have if you plan on upgrading your system to Windows 11. So what exactly is TPM and do you have it?

What exactly is TPM?

TPM is a tamper-resistant hardware technology tasked with generating and storing encryption keys inside it for better PC security. It can be remotely used to authenticate hardware and software by utilizing a unique endorsement key placed into the hardware itself. This technology can be used for example in BitLocker inside Windows in order to have data on a hard drive encrypted so if the mentioned drive is connected to another computer it would not be able to be accessed since the encryption key is stored in the TPM module. Microsoft is pushing its agenda that Windows 11 must be and must feel like safety first OS which will protect user data and user information and requiring TPM means that each Windows 11 will be secure so no additional software patches will be required for an extra layer of security. Windows 11 will assume that each user has TPM encryption enabled and will be built upon that.

Do you have TPM on your computer?

If your computer or hardware has been purchased in 2016 or later there are very high chances that you already have the required technology to run Windows 11. Unfortunately, many gaming motherboards have not been placing TPM in their boards and you might not have it. Also, there is the option of you having it but it is turned off in motherboard settings making Windows unable to detect it. As you can clearly see there are a lot of scenarios around required tech and honestly it is a complete mess. But lucky for you there are ways to find out do you possess the needed module in order to make an upgrade. On your current computer on which you would like to make an upgrade in your current Windows OS press ⊞ WINDOWS + R to open the run dialog. Inside run dialog type in TPM.msc and press ENTER to open Trusted Platform Module Management on Local Computer. You will immediately receive information do you have the required module. If everything is fine, you are good to go, however, if it says that compatible TPM cannot be found there is a chance that either you do not have needed hardware or it might be turned off inside motherboard settings.

Check motherboard UEFI

If you have a newer motherboard but Windows utility cannot detect TPM there is a chance that it might be turned off directly on your board. In order to check this, you will have to boot up your PC into UEFI either by pressing the corresponding key when it is turned ON or from Windows reboot options. Once you are inside UEFI you need to find security options and see if there is an option to turn ON or enable TPM. Since every motherboard is different and has different UEFI software we cannot cover all of the permutations and the best we can do is hope that provided information is enough. You can also visit your motherboard manufacturer to see instructions for your specific case.

Conclusion

TPM itself is generally an OK idea and I can surely see good sides of it but there is this lurking feeling that generally, Microsoft is not really concerned about the security of our data and that the real requirement for this is trying to battle software piracy. I simply cannot trust company which introduced tons of telemetry tracking through ages and which has done everything in their power to battle non-legal use of their software. I do not promote piracy but I support free choice and besides, who can tell me what will happen if TPM malfunctions, will I lose all of my data forever? It is not so uncommon that TPM has malfunctioned in the past and it is only logical to presume it can do it again in the future but this time we will not have the choice not to use it, we will be forced into it.

If you encounter the “We couldn’t install some updates because the PC was turned off” while trying to run Windows Update on your Windows 10 computer, then read on as this post will give you a couple of suggestions you can use as a reference to fix this error. Make sure to follow the options given below carefully.

Option 1 – Perform basic computer troubleshooting

If you get the “We couldn’t install some updates because the PC was turned off” error on your laptop, then it’s recommended that you connect your laptop to a power source and then try clicking the Update button again. In addition, you also have to make sure that your computer stays awake until the Windows Update process is completed. This will ensure that your computer does not go into an idle state and interfere with the process.

Option 2 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• 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 start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic and the MSI Installer
• Next, go 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.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 3 – Try restarting the Windows Update Services

• Open the Services Manager.
• From there, make sure that you set the following services and Startup types:
  • Background Intelligent Transfer Service: Manual
  • Cryptographic Service: Automatic
  • Windows Update Service: Manual (Triggered)

Option 4 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the “We couldn’t install some updates because the PC was turned off” 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. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try to install the Windows Updates manually

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.

Option 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows update error. 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 your Microsoft Edge browser and Windows Store apps are now unable to connect to the internet after you have just installed the newly released Windows 10 v1809 October 2018 update, then this post might help. As you know, Microsoft has made a change recently and because of this, some users are getting the “Hmm, we can’t reach this page” error when they try to open Microsoft Edge as well as other pre-installed apps like News, Mail, and so on. Aside from that, you also won’t be able to connect the Microsoft Store apps to the internet. What’s strange is that you can connect to the internet using other programs like Google Chrome, Internet Explorer, and many more. Apart from checking your internet connection, there are other things you can to resolve the problem. If your Windows Store apps are not able to connect to the internet and you’re only getting the Error 80072EFD, then you might have to enable IPv6 as the new Windows 10 v1809 requires IPv6 to be enabled so that you can use the UWP apps. And so you have to enable IPv6 in the network card along with IPv4. To do so, follow the steps below. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: After that, type “ncpa.cpl” and hit Enter or click OK to open Network Connections. From there, you will see your currently connected network profile. Step 3: Right-click on your network profile and select Properties and then go to the Networking tab and look for the “Internet Protocol Version 6 (TCP/IPv6)” and select its corresponding checkbox. Step 4: Now click the OK button to save the changes made and restart your computer.

What is Webguard?

Developed by Interesting Solutions, Webguard is a tool supposedly used for tracking those online who’ve developed a habit of tracking you. The application would provide logical analysis into a user’s website history, providing insight on what websites you’ve visited and also how persons are able to track your every move while browsing. While Webguard is unable to dispose of who specifically is tracking your computer usage, they’re able to determine what computer installed tracking codes or cookies on your computer system. In this case, it’s then left up to the user’s discretion to determine who they want to allow or block from tracking their online use.  Overall, this application allows the user some measure of freedom and control over their online experience. Like any other application, however, which has landed themselves a spot on Virus Total, Web guard has hidden agendas. At a distance, Webguard installs a service for Windows but later distributes advertisements. Technical details about Webguard include:

Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of Webguard Potentially Unwanted Program

While Webguard claims to track your computer usage, information reported by the application isn’t sufficient for the common computer user. This brings us back to the ulterior motive or principal objective of developing Webguard – to advertise and generate revenue from clicks made by users on Ads displayed on Internet Browsers – namely Chrome, Internet Explorer and Firefox. Why should a computer user remove Webguard? Simply, it compromises one's Internet privacy and security and it keeps abreast of your Internet history. If you’re online for an extended period, you’ll see what Webguard does. While the publishers behind the application did not alert users to the use of web beacons, cookies for tracking, and other related tracking technology, that’s not why Webguard is considered unwanted. The program is potentially unwanted because of the unpredictable advertisements it displays. Not all sites are trusted and so it’s difficult to determine, in some cases, what websites are legit for business.

Remove Webguard with Spyhunter

In most cases, at least from what I’ve seen, Webguard is installed as a single application. After it was installed for this assessment, it could be found in ‘All Programs”. This meant that one could manually delete the application from their computer system (see manual steps below). However, is that really sufficient to completely rid your PC of Webguard’s blueprints? While you might opt to remove Webguard manually – maybe because it’s more economical – an automated process is able to completely eradicate hidden threats from Webguard. In comparison to manually removing Webguard, Spyhunter penetrates your computer system for all infections. In most cases, nasty threats are unable to be removed manually. Additionally, Spyhunter not only removes installed threats, but it detects incoming ones – hence, acting as a preventative tool. Furthermore, Spyhunter detects cookies placed on your computer by Webguard. These are all undetectable threats and so an automated tool, as Spyhunter, should be used to remove Spyhunter effectively from your computer.

Manual Steps for Removal of Webguard

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: Locate the CONTROL PANEL on your computer using the SEARCH option.
• Step 2: Once the search box appears , input 'CONTROL PANEL'.
• Step 3: The Control Panel option will then appear. From the menu, choose the "Programs" option.
• Step 4: Another menu will appear. Select "All Programs and Features".
• Step 5: From the 'Programs list', search for the Webguard application.
• Step 6: Right-click on Webguard when it's found.
• Step 7:  Choose the "Uninstall" option.
• Step 8:  Follow the uninstall wizard instructions until the Webguard application is fully removed.

Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.

Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:

Find and/or install the font that you wish to use

There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.

Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)

Create REG file

Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"="NEW-FONT"

All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".

Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG

Apply changes

Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.

Rolling back

If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"="segoeui.ttf"
"Segoe UI Black (TrueType)"="seguibl.ttf"
"Segoe UI Black Italic (TrueType)"="seguibli.ttf"
"Segoe UI Bold (TrueType)"="segoeuib.ttf"
"Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf"
"Segoe UI Emoji (TrueType)"="seguiemj.ttf"
"Segoe UI Historic (TrueType)"="seguihis.ttf"
"Segoe UI Italic (TrueType)"="segoeuii.ttf"
"Segoe UI Light (TrueType)"="segoeuil.ttf"
"Segoe UI Light Italic (TrueType)"="seguili.ttf"
"Segoe UI Semibold (TrueType)"="seguisb.ttf"
"Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf"
"Segoe UI Semilight (TrueType)"="segoeuisl.ttf"
"Segoe UI Semilight Italic (TrueType)"="seguisli.ttf"
"Segoe UI Symbol (TrueType)"="seguisym.ttf"
