As you know, the Windows 10 Action Center has a stack of all the notifications that come from different applications on your computer. So each time an app displays notifications, it will be displayed for about 5 seconds and then it disappears right away. Although the allotted time for the notifications to be displayed is quite enough to catch your attention and help you get a glance at the message, there are times when you might miss it and you hoped it could’ve been displayed a lot longer. So in this post, you will be guided on how you can increase or decrease the display time of the notification in Windows 10. The best way you can view the missed notification is to click on the Action Center. From there, you will see all the notifications that are grouped by the applications. This means that if you have a lot of notifications, it would be hard for you to find what you are looking for. Thus, in such cases, the best way you can do is to increase the display time for which notification to stay on the screen.

To get started, refer to the instructions given below.

Step 1: Tap the Win + I keys to open Settings. Step 2: Next, navigate to Home > Ease of Access > Display. Step 3: After that, scroll down to the end until you see the dropdown to change the notifications where you should see the “Show notifications for”. Step 4: Then you can change the time from the default 5 seconds to 7, 15, 30, and so on. Step 5: Once done, the display time of the notifications should stay longer but keep in mind that you must choose the length wisely so if you have notifications from a lot of apps, then the screen will also be filled with multiple notification cards.

Sometimes, some applications after they are installed will put their shortcut in the context menu (right-click on desktop) for easy access, most of the time these are some system tied applications like AMD and Nvidia control panels or archives like WinRAR or 7ZIP but it can happen even for some usual application to do this.

There are some applications that you use frequently and they could be worth putting in the context menu, if you want to avoid clutter on the desktop or in the taskbar this is the third place that you should consider placing shortcuts.

If you wish you can even add a keyboard shortcut to launch this specific application. To do this select entry that you have created and edit the default value, inside the edit string in the Value data field type first & and after that key that you would like as a shortcut. Now after right click if you hit your shortcut key app will be launched right away.

Adding command

The next task is to create a command key that will actually hold the command to launch the application. Right-click on the entry that you have created, hover over New, and click on Key.

Next, you’ll need to create the command key that will actually hold the command used to launch the application. Right-click on the new Notepad key, and then choose New \ Key from the menu. Name this key 'command', all in lower case and without hyphens.

Now in order to finish setting the launcher, you need the full path of the file that you would like to run. Locate your file in file explorer or in another tool and copy its path by SHIFT + right-clicking on the file itself and choosing copy as path option.

Now click on the command key and double click on the default key on right to edit it, inside the field value data paste your path to executable. close and save the registry and you are done.

If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

• First, go to Settings > Devices > Printer and Scanners.
• After that, select the printer and select the Remove Device option.
• Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.

• Once you’ve created a System Restore point, 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.
• Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage

Error Code 0x8007232B (Code 0x8007232B) – What is it?

Error code 0x8007232B (Code 0x8007232B) is an error that occurs when you attempt to activate Windows Server 2008 or Windows Vista.

Common symptoms include:

• Attempting to activate Windows 7, Windows 8, or Windows Server 2012 and you receive an error message.
• The error message says: “Windows could not be activated. Key management services host could not be located in domain name system, please have your system administrator verify that a KMS is published correctly in DNS”
• The error message says “The directory name, file name, or volume label syntax is incorrect”.

Error Causes

• Error Code 0x8007232B occurs when you attempt to use media that is volume licensed to install: Windows 8, Windows 7, Windows Vista Enterprise, Windows Vista Business, Windows Server 2012, Windows Server 2008, Windows Server 2008 R2.
• This error code also occurs when the activation wizard is unable to connect to a Key Management Service host computer.

Further Information and Manual Repair

Error code 0x8007232B can be seen when you are trying to activate windows, on several different operating systems. This problem can usually be easily corrected, but in the event that it can't, please contact a computer repair technician. When you try to install any of the previously mentioned Windows products, they use a generic product key to install the volume-based license software. If you do have a KMS host computer configuration and see these error codes, that means the correct DNS entries are not being seen on the computer. If there is not a KMS host computer setup, you need to do this setup, otherwise switch to a MAK product key method, and activate the volume license installation that way.

Method One:

Using a Multiple Activation Key as opposed to KMS activation

1. Click the Start icon, click on All Programs, click on Accessories, right-click on Command prompt.
2. Click on “Run as administrator”. Type in the password or provide confirmation if prompted for administrator password or confirmation.
3. When asked for the command prompt, enter in the following and then hit the Enter buuton: slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx  Note: this placeholder represents the MAK product key.

Method Two:

Configure a KMS host server for the clients to activate against.

A KMS host server needs to be configured for the clients to activate against. When there are no KMS host servers configured near you, install and activate a KMS server key. After this, configure a computer on the network to host this KMS software and publish the Domain Name System (DNS) settings.

Method Three:

When the client cannot locate a KMS host on the network for activation:

1. Verify that your computer has the KMS host installed and activated by using a KMS key that is registered in DNS. You will follow these steps to do that:

1. Click the Start button, click on All Programs, click Accessories, and then right-click on Command Prompt.
2. Click on Run as Administrator. Type the password or provide confirmation if you are asked for an administrator password or for confirmation.
3. In the command prompt box, type the following command and press ENTER: nslookup -type=all _vlmcs.tcp>kms.txt
4. Then open the KMS.txt file generated by this command. The file will contain at least one entry that relays the SRV service location.

2.  A KMS host server registers a DNS SRV record once every 24 hours by default. You should check the registry to see if the KMS host server is registering with the DNS. Follow these steps to do so:

1. Click on Start, type in regedit, and then press Enter.
2. Locate HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSL and then click on it.
3. The KMS server does not register in DNS if the DisableDnsPublishing subkey is existing and has a value of 1. If this subkey is missing altogether, create a DWORD value called the DisableDnsPublishing. If the dynamic registration is suitable, the subkey value should be changed to 0. Right-click DisableDnsPublishing, click on Modify, enter 0 into the Value data box, and click OK.

If you got an error message saying, The INF file you selected does not support this method of installation while trying to install a driver using the “Install” option in the right-click context menu, read on as this post will guide you in fixing the problem. The INF file mentioned in the error message is a text file that’s divided into different types of formatted sections. Each one of the sections is designed for a particular purpose. For instance, one section is designed to copy files or to add entries to the registry. INF files are used to install drivers. However, if something is wrong, you might encounter this error while installing a driver on your Windows 10 computer. To resolve this problem, you can try to download the driver again from the official manufacturer website or check if the driver is compatible with your computer’s operating system architecture or you can also try installing the driver from the Device Manager. For more details, follow the given options below.

Option 1 – Try downloading the driver again from the official website of the manufacturer

Usually, you shouldn’t encounter this kind of issue no matter what installation method you used on your Windows 10 PC. However, there are times when the driver itself is corrupted for some reason which is why you are unable to complete the installation and receive an error message instead.

Option 2 – Try checking if the driver is compatible with the OS architecture

It is possible that you’re getting this error if you have a driver that is compatible with a 32-bit system and you are trying to install it on a 64-bit system and vice versa. Thus, you need to check if the driver you are trying to install is compatible with your operating system if you haven’t done it when you’ve downloaded the driver from the website of the manufacturer. To check the system architecture, in the Start Search, type “msinfo32” in the field and hit Enter to open the System Information window. From there, you should see all the information about your operating system. In addition, you can also search “system information” in the Cortana search box and look for the System Type entry and open it.

Option 3 – Try installing the driver from the Device Manager

If you have the driver files on your PC and you have to update a driver, refer to the steps given below to be guided on how to install the driver from the Device Manager.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the driver you want to update, and then right-click on each one of them and select the Update Driver from the menu.
• After that, click on the “Browse my computer for driver software” option.
• Next, select the “Let me pick from a list of available drivers on my computer” option and then click the Next button.
• On the next screen, you should see the “Have Disk” option. Click on this option and then click on the Browse button to go to the location of the file. After that, you shouldn’t have any problem installing the INF file.

Option 4 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the “The INF file you selected does not support this method of installation” error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Now restart your computer.
