Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer.

Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer.

Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers.

You can then go to the manufacturer’s website and compare the dates.

For a new Windows operating system, you no longer have to go to the manufacturer's website though. All you have to do is click on Update Driver and it will automatically search for updates online.

  • Type each one of the following commands.
net start wuauserv net start cryptSvc net start bits net start msiserver
  • After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Should you build a custom PC

Building your own custom PC system can be one of the greatest things you can do to your budget. Instead of going for a rebuild, we will go into detail about why building your own PC is a much better option. Also, note that if you do not possess enough technical knowledge about a topic there are plenty of stores that will offer you advice on components and after all, you can always get help from a friend.

Custom PC

So without further diversion from the topic, let us explore all the benefits of building a custom computer.

Building a custom PC is cheaper

At the first look, this statement does not feel right since when you look at the prebuilt systems you get a feeling that it is much cheaper than do it yourself variant and although CPU and GPU seem like a great deal I beg you to look under the hood on other components. Usually to lower price compromise would be made on other crucial components like SD or power supply, a PC case, or motherboard so even if you have a good CPU and GPU that will not matter much since other components would not be able to catch up with them. After all, prebuild computers will need to pay people who are building them and there is no way that will be cheaper if you just plain went and bought the same components yourself and install them.

When you are in control in choosing each component there is not only being cheaper online, it is flexibility with building itself. You choose which components you want to be stronger and which to be normal. Also, you can choose the exact model of the given component leaving you more in control and open to future upgrades.

More flexibility

Also, it may sound irrelevant but when building your own custom PC you can also choose which company you would like to purchase for each model, yes considering the CPU it is AMD or Intel but when you are buying a case, SSD, GPU, and other components choosing the right company for your needs is also the thing that should not be overlooked.

You can customize it the way you want

Not really a quality argument but with a custom PC build, you can choose would you like that RGB component or not, you choose do you like white or black fans, and many more things. You really can place a personal stamp on the computer making it indeed a personal computer.

You choose OS and applications

When you buy an already prebuilt PC, usually it comes with some sort of OS on it, sometimes it is freedos, Linux and sometimes it is Windows Home. When you get your hands dirty you can place whichever system you want on it and install applications that you use and know and some preinstalled typical apps.

There’s no Incognito Mode in Chrome
As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: 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. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:
  • 0 – Incognito mode is enabled by default
  • 1 – Incognito mode is disabled
  • 2 – Chrome is forced to always open in Incognito mode

Backup and Restore pinned Taskbar Items
Pinned Windows 10 Taskbar Items. One of the most used interfaces in the Windows environment is the Taskbar. It is where users like to pin their most-used programs as well as shortcuts with extra privileges and automated tasks. In fact, it’s a lot better than the Start Menu. So if any Windows Update messes up with your computer, or if you’ve just switched to a different computer, setting up the Taskbar with the very same set of programs you used to have is definitely not an easy task. But worry not as this post will guide you on how you can backup and restore the items on your Taskbar either manually or automatically.

Manual Backup:

  • Tap the Win + R keys to open the Run prompt.
  • Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the folder where you can see all the shortcuts or pinned items in the Taskbar.
  • After that, copy all the files in the folder and paste them somewhere else as a backup. For instance, E:\Pinned Items Backuppinnedshortcuts.
  • Next, tap the Win + R keys to open the Run prompt once more, and then type “Regedit” in the field and hit Enter to open the Registry Editor. When the User Account Control dialog box appears, click Yes.
  • After opening the Registry Editor, navigate to this key – HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband
  • Then right-click on the Taskbar folder and select Export.
  • Now save the file with the .reg extension to another location like the E:\Pinned Items Backup folder and then name it.
  • Close the Registry Editor.

Manual Restore:

Make sure to copy all the files to one of the drives if you are using another computer and then refer to the following steps.
  • Tap the Win + R keys to open the Run prompt.
  • Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the same folder where you just copied all the shortcuts. Make sure to keep it open.
  • Then open the backup folder where you saved all the pinned items and copy all the files there.
  • Next, go to the Taskbar folder (%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar) and then paste your files in there. If you encounter a problem while doing so, just replace it with your own set of files.
  • After that, go to E:\Pinned Items Backuppinnedshortcuts and then double click on tb-pinned-items.reg. If a User Account Control prompt appears, click Yes. This will add the registry file into the main registry hub. You will also get a dialog box that will confirm that data has been added to the registry successfully. Click OK.
  • You should now see the items on the Taskbar. You have to restart Windows Explorer. To do so, end its process in the Task Manager.

Automatic Backup:

Backing up and restoring the pinned Taskbar items in your Windows 10 computer can be done automatically as well. But before you get started on the process, you need to understand what’s going on behind the hood first. First, you need to create two bat files and name them “Backup Pinned Taskbar Items” and “Restore Pinned Taskbar Items”. After you have that covered, refer to the following steps:
  • Open the Notepad app and paste the following details and save it as “Backup Pinned Taskbar Items.bat.
REG EXPORT HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband “E:\Pinned Items Backuptb-pinned-items.reg” xcopy “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” “E:\Pinned Items Backuppinnedshortcuts” /E /C /H /R /K /Y
  • After that, run the newly created bat file with admin privileges.

Automatic Restore:

  • Open the Notepad app and paste the following details and save it as “Restore Pinned Taskbar Items.bat”.
REGEDIT /S “E:Pinned Items Backuptb-pinned-items.reg” xcopy “E:Pinned Items Backuppinnedshortcuts” “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” /E /C /H /R /K /Y
  • After that, run the bat file with admin privileges.
Note: Just so you know, there is a drawback to this process as we’ve noticed that any pinned apps that were downloaded from the Windows Store don’t appear in these places and any items downloaded and installed separately from the internet and then pinned.

Using ???? and other emoji in Windows
Did you know you can use emoji in file names inside Windows 10? It is no secret that emojis are basically everywhere and Microsoft has seen this and integrated them into Windows itself, so you can name files using emojis or combine them with text. Placing emojis in file names or in the text is extremely easy, all you have to do is press ⊞ WINDOWS + . and the emoji dialog will open from where you can find which emoji you would like to use. And that's it, you just used emoji for the file naming.

!!!NOTE!!!

In theory, some applications may not like these emojis if they don’t support Unicode characters. However, modern applications are designed to work with a broad set of languages that should properly support emojis. For example, the classic Windows Command Prompt can’t see emoji characters in file names properly, but both PowerShell and Microsoft’s new Windows Terminal can display them properly. If you do run into a problem, you can always open File Explorer and rename the affected files and folders to remove the emoji characters. You can then use those files in applications that don’t properly support emoji file names.
