Next-generation of RAM, DDR5 supposed to hit shelves around late summer or fall in 2021if everything goes as planned. Its goal is to increase speed and efficiency, wants to pack more memory in a single stick, and have better power management.

Hardware requirements for DDR5

Using the latest memory technology will require other hardware to follow certain standards and the first ones that will need to follow are CPUs and Motherboards. Intel is already prepared with its Alder Lake CPUs that suppose to come out also later this year. AMD on other hand has not stated anything at the time of this writing but it is a bet that their next generation that will come in 2022 will have full support. It is speculated that bot companies and their respective CPUs will have both support for DDR4 and DDR5. A story about motherboards is a little different. Motherboards will support DDR4 or DDR5 memory banks, not both, so make sure that your motherboard will support the memory you plan on getting.

Capacity of memory

The goal and aim for the DDR5 memory stick are to reach a whopping 126GB per stack. This will be done by using a dual in-line module or DIMM enabling larger capacity. That being said, the first modules that we will see are more likely to be 16GB as standard and 8GB as low entry ones.

Power consumption of DDR5 memory

The standard voltage that DDR4 operates under is 1.2V. DDR5 wants to lower this to 1.1V without sacrificing speed. Voltage regulation on modules themselves will be now integrated on memory banks instead of leaving that to motherboards which will help to detect memory errors directly on the memory bank.

Speed of memory

The most common speed of DD4 memory banks is 2,666MHz, more expansive ones go from 3,600 to 4,000MHz. DD5 aims to raise this bar to 4,800MHz and offers greater speed.

Should you get it right away?

Hardware is ever-evolving, we have PCIe 3.0 to PCIe 4.0, and taking into account that sometimes the newest tech can cause some unexpected behavior it is always the best strategy to wait for a little. Price for the newest tech has also been in its heist just when it is released and seeing how DDR5 will benefit mostly servers mostly since even today memory, processors, and other available equipment can tackle all daily tasks.

In this post, you will be guided on how you can turn on or turn off the Tailored Experiences feature in Windows 10 using three methods – via Settings, Registry Editor, and Group Policy Editor. The Tailored Experiences feature in Windows 10 helps Microsoft in delivering recommendations about Microsoft Products. The diagnostic data that comes with it allows Microsoft to know about its consumers’ experiences as well as collect feedback. To simply put it, tailored experiences are personalized tips, ads, and recommendations that enhance Microsoft products and services for consumer needs. And when you enable this feature, Windows will collect information from your browser, apps, features, and many more. After collecting information, it will offer contents that are tailored based on the data gathered on the lock screen of your computer, Windows tips, and other related functions. On the other hand, the diagnostic data is the one that allows Microsoft to get feedback from the customer. So if you’ve noticed some prompts when you use Windows that ask you about the experience, that’s actually a part of the diagnostic data. A lot of users find this feature useful. However, there are also skeptical ones that don’t share the same sentiments. If you are one of the skeptical ones, you actually have the option to turn this feature off if you do not want Microsoft to show ads, recommendations, and so on. It is also recommended that you enable the Diagnostic Data collection as you can choose to delete any collected data, as well as control the feedback frequency from Automatic to Once a day, or once a week, or to never. As mentioned, there are three methods you can choose from to either turn on or turn off Tailored Experiences. You can do it via Settings, Registry Editor, and the Group Policy Editor. To get started, follow the options provided below.

Option 1 – via Settings

To turn on or off Tailored Experiences using Settings, refer to these steps:

• Go to Settings and here, click on Privacy.
• Next, go to Diagnostic and Feedback.
• From there, toggle off the control under the Tailored experiences option to turn it off or toggle it on, if you want to turn it on.

Option 2 – via Registry Editor

To turn on or off Tailored Experiences via Registry Editor, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPrivacy
• After that, look for the DWORD named “TailoredExperiencesWithDiagnosticDataEnabled” and change its value to 0 if you want to turn it off or 1 if you want to turn it on.

Option 3 – via Group Policy Editor

To turn on or off Tailored Experiences using the Group Policy Editor, here’s what you have to do:

• Tap the Win + R keys to open the Run prompt and type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this policy setting: User ConfigurationAdminstrative TemplatesWindows ComponentsCloud Content
• Here, double click on the “Do not use diagnostic data for tailored experiences” option and select Enabled. Once you do that, you will see the following description:

“This policy setting lets you prevent Windows from using diagnostic data to provide tailored experiences to the user. If you enable this policy setting, Windows will not use diagnostic data from this device (this data may include browser, app, and feature usage, depending on the “diagnostic data” setting value) to customize the content shown on the lock screen, Windows tips, Microsoft consumer features, and other related features. If these features are enabled, users will still see recommendations, tips, and offers, but they may be less relevant. If you disable or do not configure this policy setting, Microsoft will use diagnostic data to provide personalized recommendations, tips, and offers to tailor Windows for the user’s needs and make it work better for them. This setting does not control Cortana tailored experiences, since there are separate policies to configure it.”

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try selecting the correct port for your Printer

If the first two options given above didn’t work, then maybe it’s time to select a correct port for your printer since the wrong port has been selected which is why you’re getting the “Port in use, please wait” error.

• Open “Devices and Printers” from the Start search.
• Next, look for your printer from the list of devices and right-click on it, and then select Printer Properties.
• Now go to the Ports tab under the newly opened Properties window and make sure that the port type matches the connection on the list of ports currently in use.

The Microsoft Photos app is a useful tool that allows users to view, edit, as well as create videos on their Windows 10 computers. Although it works just fine most of the time, there are some instances when you might encounter some issues when using it. One of these issues is when you cannot save media from the Photos app after you’ve edited an image. This is most likely related to a permission issue. However, according to some users, they got the error where the edited media file can’t be saved. When you encounter this kind of error, you will see the following error in your Photos app:

“It looks like you don’t have permission to save changes to this file. Try saving a copy instead.”

There are several options you can explore to resolve this error. You can try updating the Microsoft Photos app or verify the ownership of the destination folder. You can also re-register and reinstall the app. For more detailed instructions, make use of the options provided below.

Option 1 – Try to update the Microsoft Photos app

The first thing you can do to fix the problem is to update the Microsoft Photos app.

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 2 – Try to verify the ownership of the destination folder

The next thing you can do to fix the error is to verify the ownership of the folder because chances are, the location where you’re trying to save the file might not have enough permissions to read and write the file to the disk. Thus, you need to take ownership of the folder by following these steps:

• Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
• After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Next, type and enter this command: TAKEOWN /F <path>
• Note that the <path> is the location of the folder or file in File Explorer.
• Now type and enter this second command: ICACLS <path> /grant administrators:F
• Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 3 – Try resetting the Photos app

If the first option of restarting the background process of the Photos app didn’t work for you, you can try to reset the Photos app so that it will use the default factory settings. Note that this option works when you are experiencing this issue after making a couple of changes in the Photos app.

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 4 – Try reinstalling the Photos app

If none of the first two options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted.
