Change Font Size in Sticky Notes in Windows
Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

Prompted For A Product Key On Windows 10 - How to Fix It

Prompted For A Product Key – What Is It?

Some Windows 7 or Windows 8/8.1 users are having a hard time upgrading to Windows 10 as they are being prompted for a product key. By default, the Windows 10 operating system does not require a product key and users should not be prompted for one, given you upgraded your computer from an activated Windows 7 or Windows 8/8.1 license or from the Windows 10 Preview build. However, there are some users encountering this problem and there are several reasons for this.

Solution

Restoro box imageError Causes

There are a few reasons why some users are being prompted for a product key when upgrading to Windows 10:

  • Windows 7 or Windows 8/8.1 license is not activated.
  • You’re upgrading to Windows 10 final release from a preview build.
  • There are broken operating system files.
  • Activation servers get overwhelmed due to the high volume of upgrades.
  • The Windows 10 copy you downloaded does not correspond with the current Windows system you are upgrading from.

Further Information and Manual Repair

Before you can fix this problem, you need to know why you’re being prompted for a product key. Some things you should know about Windows 10 product key activation are the following:

  • You cannot activate Windows 10 using your Windows 7 or Windows 8/8.1 product key. Windows 10 has a unique product key.
  • Error codes such as 0x8007232b, 0XC004E003, 0x8007007B, or 0x8007000D might pop up during system upgrade especially when the activation servers get overwhelmed with the high volume of upgrades.
  • You don’t really need to know your Windows 10 product key.

Now, if ever you’re prompted for a product key when you’re upgrading to Windows 10, you can apply the following methods:

Method Two: Download A Copy of Windows 10 Corresponding Your Current System

One of the reasons Windows users are being prompted for a product key when upgrading to Windows 10 is that they have downloaded a wrong edition of Windows 10 and do not correspond with your current system.

  • Users of Home Basic, Home Premium, Windows 7 Starter, Windows 8.0 Core, and Windows 8.1 Core should download Windows 10 Home ISO.
  • Users of Windows 7 Ultimate, Windows 7 Professional, Windows 8.0 Pro, and Windows 8.1 Pro should download Windows 10 Pro ISO.

NOTE: Users of Windows 7 Enterprise, Windows 8.0 Enterprise, and Windows 8.1 Enterprise are not eligible for the free upgrade offer.

Method Three: Ensure Windows Is Activated

If your Windows 7 or Windows 8/8.1 is not genuine or activated, you will get prompted for a product key. You need to make sure first your current system is activated.

  1. Click on Start then right-click Computer. For Windows 8 and up users, you can simply press on Windows key + X then select Choose Properties.
  2. When the Properties window appears, check if the Windows you’re running is activated.

Method Three: Reset License Status

  1. Press on Windows key + X.
  2. Select Command Prompt (Admin).
  3. Once the command prompt window appears, type vbs –rearm then press Enter.
  4. Exit Command Prompt then restart your PC.
  5. Input the product key by following the instructions given.

Method Four: Force Activation

  1. Press on Windows key + X
  2. Select Command Prompt (Admin).
  3. Once the command prompt window appears, type vbs –ato then press Enter.
  4. Exit Command Prompt then restart your PC.

Method Five: Run System File Checker

Another thing you can try doing is to run the system file checker utility to scan if there are any broken operating system files. In doing so, you’ll be able to detect problems that might be preventing the product activation of your Windows 10 upgrade.

Method Six: Contact Microsoft Activation Center

If in case you’ve exhausted all your resources and you are still being prompted for a product key when upgrading to Windows 10, you can try contacting the Microsoft Activation Center for further details. Check here for the appropriate telephone numbers to contact.

Method Seven: Download An Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

            - When you have two, or more, drivers installed on your computer, all you have to do is disable the other drivers. You can do this by right-clicking on the driver in the Device Manager and click the Yes box next to disable. Shut down your PC after this, disconnect the installation, and boot your computer back on.

  1. When your PC boots up after the restart, click on the Start button then click on Settings.
  1. You need to go to Update & Security, then Windows Update, and then check for updates.

            - If you are using multiple drivers and this technique doesn’t work, repeat the process in Step 3 and try to disable a different driver.

Remove an incompatible app

How to Fix CPU Not Compatible Error Message On Windows 10

CPU Not Compatible – What Is It

Some users wanting to upgrade to Windows 10 from Windows 7 or Windows 8.1 experienced errors with installation. One of these errors is CPU Not Compatible. When you click and run the “Get Windows 10” from your system tray bar, you’ll receive the “CPU is not compatible with Windows 10” error. When this happens, it might be good to check if there’s a bug or if your NX feature (a requirement for the Windows 10 installation) is enabled.

Solution

Restoro box imageError Causes

The “CPU is not compatible with Windows 10” error normally occurs when:

  • NX feature is not enabled
  • You experienced the Windows 10 bug

Further Information and Manual Repair

To successfully upgrade to Windows 10, your CPU must support Physical Address Extension (PAE), SSE2, and NX features. If any of these features are not activated on your system, it’ll cause the CPU not compatible error. However, some users still reported experiencing this error even though their CPU has these features activated. Normally, this is due to the bug that Windows acknowledged.

If any of these two scenarios apply to your computer, the following methods will help you fix the problem:

Method 1 – Check for bugs

The bug applies to some Windows 7 and Windows 8.1 systems. The bug occurs when the “Get Windows 10” app fails to recognize CPUs as being compatible. This produces a false negative result with a message, “Here’s why Windows 10 cannot be installed on this PC: The CPU isn’t supported”. To fix this bug, Microsoft released an update.

Unfortunately, the patch update (KB2976978 for Windows 8/8.1 and KB2952664 for Windows 7 SP1) to fix the bug may not be automatically downloaded to your computer. If this is the case, you need to verify first if the patch was installed correctly. To do this, follow the steps below:

  1. Click ‘Start’ and type in View Installed Updates. The “View installed updates” icon should appear. Click the icon.
  1. Go to the Search bar (Top right portion) then type the patch name for your system. Make sure that you type the correct patch name for your system since Windows 7 and Windows 8/8.1 have different names. If you find the patch, it means it’s already installed. You can now upgrade to Windows 10 without the CPU not-compatible error.
  1. But, if you can’t find it you need to install the patch manually.
  1. Go to Windows Update then click the “Check for Updates” button.
  1. Browse through the available updates and look for KB2976978 for Windows 8/8.1 or KB2952664 for Windows 7 SP1
  1. Download the right patch. You may need to reboot your system once it’s done.
  1. The downloaded patch should be applied after a day or two with the Windows Task Scheduler. Once the patch is applied, you can now upgrade to Windows 10.

Method 2 – Check CPU features and activate them if needed

A major requirement for Windows 10 upgrade is for the CPU to have Physical Address Extension (PAE), SSE2, and NX features enabled on your system. If you receive the CPU not compatible error, one possible cause is that any of the mentioned features are not available OR not enabled on your system. Here’s how you can fix this:

  1. Verify if your CPU supports the three instruction sets. You can use software that provides information like this. If all three are available, proceed to the next step.
  1. Go to your computer’s BIOS. To do this, reboot your computer. You will need to press a key specific to your computer’s manufacturer (usually it’s F12, F8, F2, or DEL).
  1. Look for the NX (No Execute Bit) settings. This is normally found in the “Advanced Configuration” menu, or something similar to this. Just take note that the NX setting can be named differently in BIOS. Some other names include EDB (Execute Disabled Bit), EVP (Enhanced Virus Protection), Execute Disabled Memory Protection or No Excuse Memory Protect.
  1. Once you’re in the NX settings, make sure that it’s enabled.
  1. Exit the BIOS and SAVE your changes.
  1. Boot your computer normally, then try upgrading to Windows 10 again through the “Get Windows 10” app found in the system tray.

Method 3 – Force enabling NX Bit

If changing the settings in your BIOS doesn’t do the trick, your final option is to force enable the NX bit in your Windows system. However, this is only applicable IF and ONLY IF your CPU does support it. To force enable NX bit, do the following:

  1. Click Start and go to command prompt (Type “cmd” – no quotes) and press enter.
  1. Copy and paste the text below to the command prompt.bcdedit.exe /set {current} nx AlwaysOn
  1. Execute the command. You will need to reboot your computer once this is done.
  1. Download and install Windows 10

Method 4 – Use a trusted automated tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

How to create a public VPN Server on Windows
As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.
  • Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
  • After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
  • Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
  • Then save the configuration and reboot your router.
Step 3: Set up a VPN server on Windows 10.
  • In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
  • After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
  • On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
  • Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
  • After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
  • From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
  • Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
  • Now click on Close to exit the configuration process.
Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.
  • In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
  • Next, click on Change Settings.
  • Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.
Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.
  • Go to Settings > Network and Internet.
  • From the list of options given, click on VPN located on the left pane to see the related settings.
  • After that, click on the “+” icon to add a VPN connection.
  • Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
  • Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.
