Fix An unspecified error 0x800700b7

If you are a kid or in your teenage years you maybe will be not familiar with Commodore 64 but we are welcoming you anyway to go with us on this journey through time and find out about one of the most influential and beloved home computer of all time.

History of Commodore

Firstly shown to the world in January of 1982, at the Consumer Electronics Show, C64 caught attention right away with its low price of only $595. Although it had some issues like limited functionality in some fields and a non-wide range of use by 1984 its price dropped below $200 and it cemented itself as an affordable home computer for the middle class. In as same year Apple has released their Apple II computer with far superior capabilities, commodore 64 remains a middle-class favorite due to its price. Also, the company has decided to distribute its homemade computer via some other means including not only just electronics stores specialized in that kind of equipment but in general shops and big department stores, through toy stores and book shops as well as through specialized dealers. This has given C64 a more competitive edge and mixed with the affordable price it soon became a staple of home computing. With sales booming and the early reliability issues with the hardware addressed, software for the C64 began to grow in size and ambition during 1984. This growth shifted to the primary focus of most US game developers. The two holdouts were Sierra, who largely skipped over the C64 in favor of Apple and PC compatible machines, and Broderbund, who was heavily invested in educational software and developed primarily around the Apple II. In the North American market, the disk format had become nearly universal while cassette and cartridge-based software all but disappeared. So most US-developed games by this point grew large enough to require multi-loading. At a mid-1984 conference of game developers and experts at Origins Game Fair, Dan Bunten, Sid Meier, and a representative of Avalon Hill said that they were developing games for the C64 first as the most promising market. By 1985, games were an estimated 60 to 70% of Commodore 64 software. Over 35% of SSI's 1986 sales were for the C64, ten points higher than for the Apple II. Everything was great for Commodore but the industry was moving forward and by the year 1988, PC compatible computers were stated to be the largest and fastest-growing home entertainment systems pushing C64 on to second place. Also, Nintendo’s gaming system has started to take hold in the world with amazing 7 million systems sold in 1988 only. By the year 1991, many developers exited the gaming market for Commodore 64 home computer system and its popularity started to fall due to lack of software and not so many hardware changes. Commodore announced that the C64 would be finally discontinued in 1995. However, only one month later in April 1994, the company filed for bankruptcy. When Commodore went bankrupt, all production on their inventory, including the C64, was discontinued, thus ending the C64's 11 and a half year production.

Legendary titles

The history of Commodore 64 is interesting ones and I believe that it has done much for computers in general, yes it ran 11 years and that seems like a small-time, but remember that it was 11 years of C64 alone, there were other computers released by the company but none except arguably AMIGA 500 has not reached that much popularity as Commodore 64. That being said the system has left some of the great titles in its catalog that are great to be played even today and have been classic games on other platforms, even on PC itself.

If you suddenly encounter the SPECIAL POOL DETECTED MEMORY CORRUPTION Blue Screen error with a bug check value of “0x000000C1” while you are using your computer then it might be due to some problem with the hardware of your Windows 10 computer. According to security experts, it is most likely caused by the physical RAM which could be due to some error in the Realtek driver for Wireless USB 2.0 as well as corruption of the files inside the RAM, and so on. This kind of problem indicates that the driver wrote to an invalid section of the special pool. On the other hand, system files like the rtwlanu.sys or nvlddmkm.sys can also trigger the SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION Blue Screen error. To resolve this Blue Screen error, you can use the options provided below as reference but before you do that, make sure to create a System Restore point first. After you have that covered, proceed to the given options below.

Option 1 – Delete the settings of the Driver Verifier Manager

• Open the Driver Verifier Manager using the Start search.
• After that, select or click on the “Delete existing settings” option and then click on Finish.
• Reboot your computer and see if it fixes the Blue Screen error or not.

Option 2 – Try to update or rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

On the other hand, if updating the Network driver didn’t help, you can also try to roll back to its previous version.

• Open the Device Manager again and then look for Network Drivers.
• Next, select Realtek <Model> Wireless LAN 802.11n PCI-E NIC from the list of Network Drivers and then double click to open a new mini window.

You can also run the Deployment Imaging and Servicing Management or DISM tool to fix the error code 0x80070424. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth

A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black.

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.

Recently, a number of Windows 10 users getting an error on their computers that state, “Windows can’t find one of the files in this theme”. According to the affected users, this error occurs at random times even when they didn’t make any changes to their computer’s theme prior to getting the error. If you are one of these users, read on as this post will help you resolve this problem. If you click on the Yes button of the dialog box where the error is displayed, it won’t fix the problem as you will still get the same error from time to time. This kind of error could be caused by the executable file named “SettingSyncHost.exe”. It is possible that this executable file is unable to sync your theme all over your computer. On the other hand, it could also be due to some problems with the active theme. To resolve this issue, you can try to change the active theme, or disable the custom screensaver or disable theme syncing on your computer, as well as run a System File Checker or run the DISM tool. For more instructions, follow the options given below.

What is PyLocky ransomware? And how does it execute its attack?

PyLocky ransomware is a file-locking malware created in order to lock important files and demand ransom from victims in exchange for data recovery. This new ransomware uses the .lockymap extension in marking the files it encrypts. It starts to execute its attack by dropping the following malicious payload in the system:

Name: facture_4739149_08.26.2018.exe SHA256:8655f8599b0892d55efc13fea404b520858d01812251b1d25dcf0afb4684dce9 Size: 5.3 MB

After dropping its malicious payload, this crypto-malware connects the infected computer to a remote server where it downloads more malicious files and places them on system folders. It then applies a data gathering module used to gather data about the user and the computer. The malicious files that were downloaded earlier along with the data obtained are used for another module called stealth protection. This allows PyLocky ransomware to execute its attack without detection from any security or antivirus programs installed in the system. It also modifies some registry keys and entries in the Windows Registry such as:

• HKEY_CURRENT_USERControl PanelDesktop
• HKEY_USERS.DEFAULTControl PanelDesktop
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

Once all the modifications are carried out, PyLocky ransomware will begin encrypting its targeted files using a sophisticated encryption cipher. Following the encryption, it adds the .lockymap extension to each one of the encrypted files and releases a ransom note named “LOCKY-README.txt” which contains the following content:

“Please be advised: All your files, pictures document and data has been encrypted with Military Grade Encryption RSA ABS-256. Your information is not lost. But Encrypted. In order for you to restore your files, you have to purchase a Decrypter. Follow these steps to restore your files. 1* Download the Tor Browser.
