CD/DVD icon is not showing in File Explorer
In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is 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. Note that the concerned drivers will be listed under the DVD/CD-ROM drives section as well as the IDE/ATAPI Controllers section.
  • From there, look for the following drivers:
    • ATA Channel 0.
    • ATA Channel 1.
    • Standard Dual Channel PCI IDE Controller.
  • Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.
Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
  • After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
  • Right-click on each one of these DWORD values and select Delete.
  • Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:
  • Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
  • From there, right-click on “ATAPI” and select New > Key.
  • After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
  • Now name it as “EnumDevice1” and double click on it and then set its value data to “1”.
  • Click OK and restart your computer to apply the changes made successfully.

Windows PC advantages over Apple Mac

In the last article, we have covered various advantages of Apple hardware over Windows PC, however, PC has their own strengths and advantages over MACs as well. Join us as we explore why would you choose Windows PC over MAC.

Windows PC

Hardware customization

If you like to customize and build your own hardware and customize your existing computer then MACs are out of the picture, on other hand, computers based on Windows operating system are much more flexible in terms of customization.

While Apple hardware is locked and only allows small changes to it, computers running on Windows are free and open to various upgrades and modifications so if you like to play with hardware Windows is your platform.

Gaming

There are games on MAC true but their numbers can not compare to games available for the Windows platform. On top of that, most latest and best gaming hardware is not even available on Apple platforms so if you plan to game in high resolutions and play the latest games there really is no option other than Windows.

Windows Platforms also has multiple emulators that you can use to play games from other older platforms and Microsoft since it owns Xbox has some great plans for both PC and Xbox gaming.

Software back compatibility

Since the introduction of the new MAC OS X, apple really lost a lot of application back compatibility, and a lot of old legacy software can not be run on modern Apple computers. Windows on the other hand have always tried and succeeded in keeping maximum compatibility with older and legacy software.

Also on the Windows platform, there is a lot of community support for old and legacy software so even if it is not officially supported it is backed up by the community.

Software variability

In terms of where can you find the most different software, you need to look no further than the Windows platform. How Windows itself has great backward compatibility and a lot of developers are using it to create new software thanks to Visual Studio and .NET Windows has cemented itself as a platform with the most available software.

The popularity of Windows as the home operating system and as a gaming platform has made it quite interesting in eyes of various developers and tons of small applications are made daily for it. Windows 11 has also brought native android support to it and that has just expanded its already impressive catalog of applications.

Freedom of choice

Overall Windows PC is most appealing for users that like to be able to choose everything, from hardware components to software they would like to use. No other platform will give you larger freedom of choice and better personalization options.

The current state of Government vs BigTech
BigTech justiceBigTech platforms Google and Facebook were hit with a series of antitrust lawsuits by the US federal government and states on charges they are operating monopolies and abusing their power. Below is the status of the cases, as well as government probes of Apple and Amazon in their current states

Two lawsuits against Facebook

In a defeat, Judge James Boasberg said the Federal Trade Commission, which had sued Facebook in December asking that Facebook be forced to sell WhatsApp and Instagram, failed to show that Facebook had monopoly power in the social-networking market, among other problems. However, the FTC could file a new complaint by July 29. He threw out a related state lawsuit entirely, saying that the attorney's general had waited too long. They are looking at their options.

Four lawsuits against Google

The US Justice Department sued Google in October, accusing the $1 trillion company of illegally using its market muscle to hobble rivals. A trial date was set for September 12, 2023. A lawsuit by 38 US states and territories accuses Google of abusing its market power to try to make its search engine as dominant inside cars, TVs, and speakers as it is in phones. This was consolidated with the federal lawsuit for purposes of discovery. Texas, backed by other states, filed a separate lawsuit against Google, accusing it of breaking antitrust law in how it runs its online advertising business. Dozens of state attorneys general sued Google on July 7, alleging that it bought off competitors and used restrictive contracts to unlawfully maintain a monopoly for its app store on Android phones.

Justice Department investigates Apple

This probe, revealed in June 2019, appears to focus on Apple's app store. Some app developers have accused Apple of introducing new products very similar to existing apps created by other developers and sold in the Apple Store, and then trying to banish the older apps from the store because they compete with Apple's new product. Apple says it seeks to have only the highest-quality apps in the app store.

Justice Department probing Facebook and Amazon

In July 2019, the Justice Department said it was expanding its Big Tech probes to include "search, social media, and some retail services online", an apparent reference to Facebook and Amazon.

Federal Trade Commission on Amazon

In its investigation of Amazon, the FTC is likely looking at the inherent conflict of interest of Amazon competing with small sellers on its marketplace platform, including allegations that it used information from sellers on its platform to decide what products it would introduce.
