Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

Keyboard shortcuts are undeniably one of the most utilized ways and are helpful in maximizing productivity through the various applications at top speed in Windows 10. It offers the option to create custom keyboard shortcuts that allow users to launch apps, and even websites, instantly. There are already tons of keyboard shortcuts that are built-in in Windows 10 but in case you don’t know, you can actually create new ones. Doing so is not a difficult task and in this post, you will be guided on how you can exactly create custom keyboard shortcuts in your Windows 10 computer. Most users would create desktop shortcuts or pin the apps in the taskbar to speed up the process of working on their computers. It is an easy task to do since you can easily do it by dragging an app from the Start Menu to the desktop or by simply right-clicking on the executable app and selecting the “Create Shortcut” option. However, doing so would take physical effort and there are times when you have to minimize all the apps to get to the desktop so you can click the shortcut and this is where the Custom Keyboard Shortcuts come in handy. You can create Custom Keyboard Shortcuts in Windows 10 for various programs – from the traditional desktop apps to the new universal apps – you can fling in a shortcut so that you can instantly open them faster compared to when doing it manually and besides this also wouldn’t affect any of the ongoing system activity. To get started, you need to follow the steps provided below carefully.

To add Custom Keyboard hotkeys to a program and website desktop shortcuts, here’s what you have to do:

Step 1: First, you have to right-click on the app or website and select Properties. Step 2: After that, go to the Shortcut tab and from there, you will see the “Shortcut key” textbox which allows you to enter a new or custom keyboard shortcut for the app or website. Step 3: In the textbox field, input your preferred letters to set up the new hotkey. Keep in mind that this custom shortcut has to be combined with the Ctrl + Alt keys which means that if you want to select “N”, you have to tap the Ctrl + Alt + N keys. Step 4: Once done, click on the Apply and OK buttons to save the changes made and then close the window. Step 5: After that, tap the newly created keyboard shortcut, Ctrl + Alt + N keys again to open the app or website you’ve set up earlier.

To add Custom Keyboard hotkeys to a desktop app or an independent program that can be installed using direct download, here’s what you have to do:

Step 1: First, open the Start Menu and look for the icon/tile of the required app in the menu. However, if you are not able to find the desired app, then just click on the All Apps option to navigate through all the apps that are installed on your PC. Step 2: Once you find the app, just right-click on it and select More and then click on the “Open file location” option. Step 3: This will open a new window with the shortcut icon. Right-click on the app’s shortcut icon and select Properties. Step 4: This will open the Properties window where you can add the shortcut combination. Keep in mind that just like the previous method, the custom shortcut has to be combined with the Ctrl + Alt keys. For instance, if you select E, then you also have to set a keyboard shortcut that includes Ctrl + Alt, so it will be, Ctrl + Alt + E. Step 5: Once you’re done, click on the Apply and OK buttons to save the changes made. You should now be able to use the custom shortcut key you’ve set.

Experiencing issues while using Remote Desktop connections is not uncommon. One of the issues that users encountered recently while trying to connect to their Remote Desktop network is the error saying, “Your credentials did not work, The login attempt failed”. If you are one of these users, then you’ve come to the right place as this post will walk you through fixing the problem. When facing this kind of problem, the first thing you can try before you do some troubleshooting steps is to verify the credentials. But if you are certain that you’ve entered the correct credentials just like what other users reported, then it’s completely a different matter. Based on the reports, this error is common on newly installed versions of Windows 10 or after reinstalling the operating system which could mean that the problem might be due to the Windows security policies or the username might have been recently modified. The latter case is a possibility especially if you’ve reinstalled Windows 10 and had entered a new username. In such a case, you will really have a difficult time connecting to your Remote Desktop connection since its credentials do not really automatically change. If you’ve verified that your credentials are correct, then now’s the time you troubleshoot the problem with the help of the potential fixes provided below. Just make sure that you follow each one of them in sequence.

Option 1 –Try to run the Network Adapter troubleshooter

To run the Network Troubleshooter, refer to these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.

• Next, click on the “Change connection properties” option.
• After that, set the radio button of Network Profile from Public to Private.
• Wait for a couple of seconds until the system is done applying the changes you’ve made and then see if you can now connect to the Remote Desktop connection.

Option 3 – Try changing the account username

As mentioned, one of the possible causes for this error is the reinstallation of the operating system. You might have changed the username for the system but it does not really change the username of the Remote Desktop connection as well. Thus, you have to change the username back to what it was before you’ve reinstalled Windows 10.

Option 4 – Try modifying the Windows Security Policy

You can also try to edit the Windows Security Policy as it could help in resolving the error. This Windows Security Policy, when enabled, will not allow non-admin users to log on to the Remote Desktop connection. So if you want to allow non-admin users to use the Remote Desktop connection, then you need to modify this policy. Note that you can only do that if you are the admin of the system yourself.

• Tap the Win + R keys to open the Run utility.
• Then type “secpol.msc” in the field and tap Enter or click OK to open the Local Security Policy.

However, from time to time, no matter how useful this feature is, users still experience a handful of issues. One of which is that they suddenly find their screen rotated or Upside Down even when they didn’t do a thing or adjust the setting. You may have pressed the shortcut on the keyboard by accident or some other program changed the setting on your computer without your permission – whichever the case is, this post will show you what you can do to fix the upside-down screen on your Windows 10 PC using the options laid out below.

Option 1 – Try using hotkeys

Note that this option has all the graphics driver properties and helps you in changing the configurations as well as control several options like refresh rate, resolution, color-depth and many more. You have to navigate to these options to see if the orientation is changed in these properties. To do so, follow the steps below.

• Right-click on any empty space on your Desktop and then select Graphics Properties or Intel Graphics Settings.
• After that, select Display from the list of sub-options that appears.
• From there, you will see the rotation of the screen under the “Display settings” option where you have to make sure that the slider is set to “0”.

There are monitors that have buttons in them that allows users to shift the rotation of the screen to 90 degrees. It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist. You could also go over your monitor’s manual if you still have it as it contains details with regards to screen rotation.

Option 5 – Update your Graphics drivers

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.
