Operating systems now give users a feature that allows them to create separate partitions out of HDD or SSD-based storage in order to store data in an organized manner. This small yet powerful feature has always been supported by Microsoft. However, there are times when users might fill up on some particular very soon. This may result in the lack of space for that partition which makes the entire process of using PCs slower since there is a large chunk of files that has to be indexed in a smaller partition. If you are one of the users experiencing this dilemma, you need to either delete the other partitions to allocate their storage to the partition that is short on storage or simply recreate the partition so that all the useless data will be deleted and you can start afresh with the overflowing partition. In this post, you will be guided on how you can delete any storage partition from your Windows 10 PC via Disk Management, Command Prompt as well as Windows PowerShell.

Option 1 – Delete storage partition via Disk Management

This is one of the simplest ways you can use to delete a storage partition. Go to the WinX Menu and from there, open Disk Management and then select the Drive you want to get rid of, right-click on it and then select Delete Volume.

Option 2 – Delete storage partition via Command Prompt

• Tap the Win + X keys or right-click on the Start button and select Command Prompt (Admin) or you could also type in “cmd” in the Cortana search box and right-click on the Command Prompt icon and then select the “Run as Administrator” option from the context menu.
• Once you have Command Prompt pulled up as admin, type in and enter this command – diskpart
• After entering this command, the Diskpart Utility will start. Diskpart Utility is a command line-based utility just like Command Prompt but it will get a UAC Prompt after you invoke it so you have to click Yes for the UAC Prompt.
• After that, type in list volume and tap Enter to see the list of all the partitions created on your PC. This includes both types of partitions that are visible to a normal user in the File Explorer as well as the ones that are created by Windows 10 by default which helps it in storing the boot files and other essential system files.
• You should see a list of all the partitions made on your computer. Select the partition you want to delete by its Unique Identification number as Volume X where X denotes the Unique Identification Number.
• Next, type in the select volume number command and hit Enter to select the desired volume.
• Then delete the volume you’ve selected and type in the delete volume command and hit Enter to delete the volume you just selected and convert it into unallocated space.

Option 3 – Delete storage partition via Windows PowerShell

• Start by tapping the Win + X keys or simply right click on the Start button and select Windows PowerShell (Admin) or you could also type in “windows powershell” in the Cortana search box and right-click on the Windows PowerShell icon and select the “Run as administrator” option.
• Once you’ve opened the Windows PowerShell, type in the Get-Volume command and hit Enter to get a list of all the partitions on your PC.
• Next, select the drive letter you want to delete and then type in the Remove-Partition –DriveLetter command and hit Enter to delete the selected partition. Note that you need to replace the drive letter with the letter of the partition you want to get rid of.
• After that, it will ask you for confirmation. Just hit the Y key for Yes or hit the A key to say Yes to All. This will delete all the partition you’ve selected and will move them in as unallocated space.

And that’s how you delete a Drive Partition or Volume in Windows 10. Note that you should only follow the last two options given in case the Disk Management is not able to fulfill the user requirements.

ListenToTheRadioNow is a Browser Extension that allegedly lets you listen to radio from your browser. However, all this extension does is add links to the popular radio stations on your home page. This extension hijacks your home page and changes your default search provides to MyWay. While running it monitors browsing data from your browser, mining information such as website visits, clicked links, and sometimes even personal information. This information is later used to display targeted ads through your browser. Several anti-virus scanners have marked this extension as a possible Browser Hijackers, and due to its data mining nature, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking is a type of unwanted software, commonly a browser add-on or extension, which then causes modifications in the web browser’s settings. Browser hijackers could do more than just modifying homepages. In most cases, browser hijacking is used for earning ad revenue that comes from forced advert clicks and website visits. Even though it may seem naive, all browser hijackers are dangerous and therefore always regarded as security threats. They don’t just ruin your internet browsers, but browser hijackers could also modify the system registry to make your PC susceptible to other malicious programs.

How you can know whether the browser is hijacked?

There are several symptoms of browser hijacking: 1. home-page is changed 2. new bookmarks pointing to porn websites have been added to your bookmarks 3. the default internet search engine and/or the default web browser settings are altered 4. find new toolbars that you did not add 5. unstoppable flurries of popup ads show up on your PC screen 6. webpages load very slowly and often incomplete 7. you have prohibited entry to certain web pages, for example, the site of an anti-malware software firm like SafeBytes.

So how does a browser hijacker infect a PC

A browser hijacker could be installed on your computer or laptop if you visit an infected website, click on an e-mail attachment, or download something from a file-sharing website. They also come from add-on programs, also referred to as browser helper objects (BHO), browser plug-ins or toolbars. Also, some shareware and freeware can put the hijacker inside your computer through “bundling”. A good example of some popular browser hijackers includes Babylon, Anyprotect, Conduit, SweetPage, DefaultTab, Delta Search, and RocketTab, but the names are regularly changing.

Tips on how to get rid of a browser hijacker

Some hijackers can be removed by uninstalling the freeware they were included with or by eliminating any extension you’ve recently added to your computer. However, most hijacking codes are not very easy to eliminate manually, since they go deeper into your operating system. Furthermore, manual removal expects you to perform several time-consuming and tricky actions that are hard to do for new computer users. Professionals always recommend users to get rid of any malicious software including browser hijacker with an automatic malware removal tool, which is simpler, safer, and faster than the manual removal technique.

You might not be able to browse to the folders and files that you want to restore in the File Restore Wizard. The cause of the error could vary depending on what error code you receive:

• 0x80070001 – If you got this particular error code when trying to back up a specific library or when you accept the default settings in Windows Backup and Restore.
• 0x81000037 – If you got this kind of error code when you try to read from the shadow copy on one of the volumes being backed up.
• 0x80070003 – If you got this error code when trying to restore the folders or files in a library by using the Windows Backup and Restore.
• On the other hand, you cannot use the Browse for files or the Browse for folders functionality.

Note that the Windows Backup or Restore failed, Errors 0x80070001, 0x81000037, 0x80070003 Error code 0x80070001, 0x81000037 occurs during backup while Error code 0x80070003 and “Browse for Files” issue occurs when you try to restore files. Whichever error codes you got, here are some possible fixes that might help.

Option 1 – Fix Windows Backup error codes 0x80070001, 0x81000037

The reason for the Windows Backup error codes 0x80070001, 0x81000037, as mentioned above, is when there is a volume that uses a FAT file system (0x80070001) and when a volume contains compressed files (0x81000037). To fix these errors, you need to remove the “reparse point” also known as SYMBOLIC LINK, and select the absolute path of this location in the Windows Backup configuration user interface. Refer to these steps to remove the reparse point.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open Command Prompt.
• Next, type the following command and hit Enter:

DIR /AL /S

• After you enter the command, it will display the JUNCTION list.
• Now to delete the mounted volume reparse point, you have to locate the reparse point you found and right-click on the reparse point icon, and click on Properties.
• Confirm that the folder Type is Mounted Volume in the General tab and then delete this folder.

Option 2 – Fix the Windows Restore Error 0x81000037

When you try to restore a deleted backed-up directory, it fails and the Error code 0x81000037 pops up. You can also encounter this error when you select to restore the files to their original subfolders check box in the File Restore Wizard and you try to restore folders or files to an alternative location, then you will encounter error code 0x81000037 which will be displayed in an error message as shown below: To fix this error, you need to re-create the missing directory using the following steps:

• Take note of the path for which the error occurs.
• Then create the corresponding folder.
• Now perform the restore operation again.

And since you might have subfolders in the deleted folder, click to clear the “Restore the files to their original subfolders” checkbox when you run the File Restore Wizard.

Option 3 – Cannot use the Browse for files or the Browse for folders functionality

There is no proper fix for this particular error but if you remember the name of the files, you can just search for them. Click on the Search button when using the File Restore functionality and then type the name of the file and when that file appears, select and click on it to restore it.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.

Option 1 – Try using Windows 10 Settings

If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.

• Open the Windows 10 Settings app.
• Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
• From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.

Option 2 – Try using the Registry Editor

• Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Afterward, if a User Account Control or UAC prompt appears, click on Yes.
• Once the Registry Editor is pulled up, navigate to this registry key: HKEY_CURRENT_USERSystemGameConfigStore
• Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name it to “GameDVR_DSEBehavior and tap Enter to save it.
• Now double click on the newly created GameDVR_DSEBehavior DWORD and set its value to “2” if you want to disable it, or “0” if you want to enable it.
• Once you entered the value, close the Registry Editor and restart your computer to successfully apply the changes made.

Option 3 – Try running the application in Compatibility Mode

If the first two options didn’t work, the next thing you can do is to run the application in a Compatibility Mode. Follow the steps below to do so:

• Go to the location of the application or game on which you need to disable or enable the Full-Screen optimization feature.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you can see the “Disable fullscreen optimization” option to disable the feature and vice versa.
• Now click on the Apply and OK buttons to apply the changes made in the application’s settings.
