Further Information and Manual Repair

To fix this particular error code affecting Windows 10 devices, you will need to employ at least one manual repair method mentioned within this article. Manual repair methods offer effective solutions as they seek to address the root causes related to Windows error codes. When the manual repair methods are implemented correctly, users are usually able to quickly overcome issues that cause Windows error codes and can thereafter access all the benefits Windows has to offer to its users.

Note, however, that in a few cases where technical skills are required, the need for a Windows repair technician may present itself. In such a case, resort to Windows forums and other resources to access help from a certified Windows professional. Also, consider using an automated tool where necessary.

Method One: Temporarily Disable or Uninstall Third-party Security Software

Some third-party security programs or antivirus software may interfere with the installation process when Windows users attempt to upgrade to Windows 10. To verify if this is the issue causing error code 0xC1900101-0x20017 on your device, temporarily uninstall or disable these applications. You may easily do so by checking the settings of these programs or visiting Settings within the Windows Start Menu.

Once you have disabled these programs on your device, reboot your machine and attempt to update to Windows 10. If the issue was caused by a third-party app, error code 0xC1900101-0x20017 will no longer occur and your machine will successfully upgrade to the version of Windows 10 you attempt to download.

However, in the case where error code 0xC1900101-0x20017 in Windows 10 reoccurs during the installation process, you will need to resort to another manual repair method listed below.

Method Two: Disable Firewall Software

Like method one, this manual repair method can be effective in combating issues related to 0xC1900101-0x20017. This is of course, dependent on whether or not the error code is due to an incompatible security program.

Temporarily disable your firewall by adjusting its settings. Once this step is complete, reboot your machine and attempt to install the latest version of Windows 10. If you are able to complete the process, this means the problem was due to an issue with your firewall. You can then enable the firewall you previously disabled or download another program as its replacement.

If the error code reoccurs, however, consider implementing the next manual repair method on this list.

Method Three: Use Command Prompt to Check for Damaged System Files

Command Prompt can be very effective in helping regular as well as technically skilled users repair issues with their PC. In the case of error code 0xC1900101-0x20017 in Windows 10, access Command Prompt using the following instructions.

• Step one: Right-click Start Menu
• Step two: Select Command Prompt (Admin)
• Step three: Type sfc /scannow

Be sure to enter the command as it is written above, with a space between “sfc” and “/scannow”. Wait until the scan is complete. If there are any errors related to system files, i.e. if any system files are damaged, corrupted, or missing, your machine will begin to fix it. Once the process is complete, reboot your PC then reattempt the Windows 10 upgrade process via Windows Update. If you are successful, it means that you have rectified error code 0xC1900101-0x20017. Otherwise, you may need to contact a Windows repair technician.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Processes tab and find the process of Windows Explorer.
• Once you find it, right-click on it and select Restart to restart its process.
• After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:

• Open the Notepad app and paste the following content in the text area:

@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on

• After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
• Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
• Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
• After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature:  POPELER SYSTEM, S.L. Entry Point:   0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

 Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation.

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.
