Fix Windows defender 0x800700AA Error

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system.
This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files.

In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

  1. Run SFC scan

    SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    In command prompt type SFC /SCANNOW and press ENTER
    Wait for the process to finish, do not interrupt it and once it is done, restart your computer

  2. Run DISM scan

    DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following:
    Press ⊞ WINDOWS + X to open the secret menu
    Left-click on the command prompt (admin)
    inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER.
    Leave scan to finish and reboot your PC

Proton Drive, privacy-first cloud storage

In 2014 Proton mail started as an end-to-end encrypted email service offering secure and private email services. Proton mail is still live and going with the same dedication to privacy and security but the company has expanded its offering into cloud storage drive services.

Starting as a public beta at the end of 2020, Proton Drive is keeping its privacy and security policy philosophy with the new service. Proton Drive is the newest service besides Proton Calendar, Proton VPN, and Proton Mail.

proton drive

Drive has end-to-end encryption for everything on it including files themselves, filenames, folder structure, folder names, extensions, and file sizes. This means that you and only you can access your files. Servers are located in Geneva, Switzerland and they are under Swiss privacy laws making sure that your files are protected. Proton services in general are all open source so anyone can take a look at them to be sure that nothing is lurking under the hood. For now, sync is done either via the android app or web interface but the desktop client will come soon since currently, it is under development.

Sadly free plan of Proton Drive will give you only 1GB of storage which is much less than other services and sadly payments plans are also not so jaw-dropping going for $4 USD per month for a 200GB plan or with Proton ultimate subscription that will set you $10 behind but you will get 500GB of drive storage. Of course, if you value privacy for your files these options are good but if you do not mind that part other services have much better options.

All in all Proton Drive is a great cloud storage solution if you need privacy and well worth the investment. With the ultimate subscription, you will get enough space for most people and company needs with other services and guaranteed privacy and security, on the other hand, if you just need a large amount of cloud storage not caring too much about privacy other options are better.

Fixing Error 0xC1900208, 0x4000C in Windows
As you know, the Windows Update process takes compatibility seriously. The Windows Updates need to be compatible with the hardware as well as all the installed applications in the computer else the Windows Updates will only get stuck in the process. Two of the Windows 10 errors that shows up during this case is the error 0xC1900208, 0x4000C. These error codes are caused by incompatible applications which means that there might be an incompatible app installed in your computer that’s blocking the upgrade process and prevents it from finishing. That’s why you need to make sure that all the applications on your computer are updated to their latest versions and then check the compatibility. So if there are any incompatible apps, be sure to uninstall them and then try doing the upgrade once again. Take note that these error codes are just among many compatibility issues that the Windows Update throws up. Since the error is caused by a compatibility issue, you have three options – first, you can update the incompatible application to the latest version, second, uninstall the application or trick Windows and make it seem like it’s compatible.

Option 1 – Try updating the application or software

As mentioned, you can try updating the concerned application or software to its latest version to resolve the compatibility issue and in turn, fix the errors 0xC1900208 – 0x4000C. Note that depending on where you had installed the application, your steps will change. So if you have it installed directly from the website, refer to these steps:
  • Look for the built-in option to check the updates since the most application has this option.
  • You also have the option to go to the website of the application and check if there is a new version available. If there is, download and update the app.
On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:
  • Open the Store and click on the three dots located at the top-right of the window.
  • Next, click the Download and Updates option.
  • From there, check if there is an update available for the store. If there is, update it.

Option 2 – Try to uninstall the application or software

If updating the app or software to its latest version didn’t help and you’re still getting the error 0xC1900208 – 0x4000C every time you attempt to install the Windows Updates, you may have to uninstall it. You will need to use the usual Program and Features to uninstall it if you have downloaded it from the website.
  • In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
  • After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
  • From there, look for the concerned program and select it and then uninstall it.
Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 3 – Try bypassing the Upgrade Advisor

There are times when a software developer fails to pass the compatibility test for their apps. It could be that they work on Windows 10 upgraded version but just didn’t pass the compatibility check. So if you are pretty certain that the app really works on Windows 10, you can just bypass the Upgrade Advisor.

Windows storeIt has officially confirmed that many open source and free applications will be in it like Opera, VLC, discord, Libre office, etc. It seems that Microsoft wants to place its store as one place to go for all of your software needs. Another great surprise is the coming of Epic games store implementation. It was officially confirmed but not explained in detail, will we have Epic store opened in Windows store or we will only get installer as a package we will see but this is some great news. As for how it states now, it seems that the Windows store aims to eliminate searching the web for applications and bring them all into one environment with reviews and ratings so you know which one to install and use. It also features a great search engine to find proper applications for your needs. The new store will come to Windows 10 as well but after all Windows 11 has been mostly released and adopted. So expect it via update in two or three months' time. It would be great if some larger companies decide to join MS stores like Autodesk, Adobe, the Foundry, etc so you can install everything you need from it but one can only hope.

Logitech lift ergonomic mouse

Recently Logitech has released a new line of ergonomic mouse products on market, strangely shaped and lifted on a vertical axis Logitech claims that these devices will fix your issues and ease your hand pains for prolonged use of the computer.

Logitech ergonomic vertical mouse

The first time I saw this mouse I was not really impressed with its looks and somehow I thought it will not feel good. This all changed when I actually started using it, surprisingly altho strange in looks it does feel much more natural and much less stressful on hand. Also, it felt like I have used it before, personally, I did not need any adjustment period in order to use it fully.

All of that being said I will admit that using it for gaming is still not an option for me, someone might find it ok, especially if they play some games that do not need to be responsive like strategies or similar but for RTS and FPS I will still stick to the typically shaped mouse. This might be just a habit for me but somehow I feel more responsive with the typical mouse, but for anything else, this is the mouse that will keep your hands stress-free.

Now in order to get the mouse to be really recommended it needs to have some good technical specifications as well, looks are not all. The less important detail is that the mouse comes in 3 different colors: Black, white and pink, and its technical specifications are:

Specs & Details

Dimensions

Height: 71 mmWidth: 70 mmDepth: 108 mmWeight: 125 g

Technical Specifications

Sensor technology
  • Sensor type: Logitech Advanced Optical Tracking
  • Dpi range: 400-4000 dpi (Fully adjustable with 100DPI increments)
  • Nominal value: 1000 dpi
Buttons
  • Number of buttons: 6 (Left/Right-click, Back/Forward, Middle button, Scroll-wheel with a middle click)
Battery
  • Battery type: 1x AA battery (included)

Connection type support
  • Logi Bolt USB receiver (included)
  • Bluetooth® Low Energy Technology
Wireless range
  • 10-m wireless range

Personally, I would recommend this mouse for anyone who does work in front of the computer during the whole workday since it really does loosen grip and strain on hands.

Microsoft Office Windows 11 edition
Microsoft has officially announced details about the newest upgrades to its office 365 suite moving forward along with its new OS release. It seems that Microsoft has listened to its user base and feedback since Word, Excel, and PowerPoint are getting much-needed redesign taking into account many suggestions from the community. The new office should feel more like an application suite guiding focus on the interconnection of applications themselves providing users with a much more natural experience of using them.

The new office features so far

From Microsoft themselves:
“This Office visual refresh is based on feedback from customers who asked for a more natural and consistent experience within and between your applications, specifically on Windows. With this update, we deliver an intuitive, coherent, and familiar user interface, using the Fluent Design principles, across all your applications: Word, Excel, PowerPoint, OneNote, Outlook, Access, Project, Publisher, and Visio. We aligned this visual refresh with the design of Windows 11 to provide seamless experiences on your PC.”
It is always refreshing to hear when a company listens to its user base and actually does what is needed instead of trying to invent the wheel.

office appsHow to switch

Since beta is already rolling and if you have an active 365 subscription to office suite visual refresh will be automatically available to all Office insiders running beta channel builds. It can be turned on and off using the coming soon feature in the top right corner of the menu in any application. Just click on the megaphone icon to open the coming soon pane and apply settings to all office apps. Note that The Coming Soon feature is not available in Access, Project, Publisher, or Visio. If you turn on the visual refresh in any of the 4 apps mentioned above (Work Excel, PowerPoint, or OneNote), it will also be available in these 4 apps.

Difference themselves

The Home tab menu still has a familiar look with a few tweaks. For example, accessing frequently used Word commands will be a lot easier. By navigating to Designer > Show Quick Access Toolbar, users can add a customizable shortcut ribbon to Word that houses conveniently placed options. Also, the office will not match your Windows operating system color theme so if you have a dark theme enabled, the office will also have a dark color theme. Color palettes are more neutral, corners are a bit softer but customizable ribbons are a win here for me.

office dark modeConclusion

There was not much said other than visual upgrades and small tweaks that were supposed to make your life easier but then again Windows 11 itself is in the same boat. I am not sure if this is a great update offering just some visual tweaks and focus on workflow mechanics or just being plain lazy and trying to cash in visuals as a completely new product.

Follow the given options below to fix the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL BSOD error.

Option 1 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues.
  • Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
  • After that, select the option “Create custom settings”.
  • Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
  • Next, select the option “Select driver names from a list” option.
  • Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
  • Then click on the Finish button.
  • Open Command Prompt as administrator and execute this command – verifier /querysettings
  • The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
  • Open the Command Prompt as admin again and run this command – verifier /reset
  • The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 2 – Try updating SSD firmware

If you have installed SSD on your computer recently and you have started getting the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL Blue Screen error since then you may have to update the SSD firmware. To fix this, you can download the Intel Solid-State Drive Toolbox from the official website. This toolbox is compatible with Windows 10 and Windows 7 and later versions.

Option 3 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.

  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try running Microsoft’s online Blue Screen Troubleshooter

If running the built-in Blue Screen Troubleshooter didn’t work, you can also try running Microsoft’s online Blue Screen Troubleshooter. All you have to do is go to Microsoft’s website and from there, you will see a simple wizard that will walk you through the troubleshooting process.

Option 5 – Try to reinstall or update device drivers of recently installed hardware

If the first few options didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • Then locate the device drivers and right-click on them to open the Properties.
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 6 – Try disabling Hardware Acceleration

You might want to disable Hardware Acceleration system-wide or for a particular program like Google Chrome and see if it resolves the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL BSOD error
