BigTech 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.

Valve has announced the first gaming PC handheld console: Steam Deck. At its core, Stead Deck is just a portable, small PC in little casing. It uses AMD Zen 2 CPU and RDNA 2 GPU architecture, has 16GB of RAM, Wi-Fi, and Bluetooth. It is a portable device with both a touchpad and joystick packing a seven-inch screen with a resolution of 1280x800 (16:10 aspect ratio). The screen has an ambient light sensor for automatic light adjustments same as your modern mobile device. Stating to Valve battery will hold up from two to eight hours depending on the activity of the user and what exactly he is doing. The handheld comes also with a carrying case.

Steam Deck operating system and software

Out of the box, Steam Dock comes with the latest Valve’s version of SteamOS 3. Just for comparing, the steam box was coming SteamOS 2, so this new Linux-based OS is aimed to provide better performance and better compatibility. Naturally, all Linux games in your Steam library will work right out of the box but Valve has something called PROTON inside OS, it is emulation software based on Wine that will supposedly let you play all of your Library games on a given OS. One big thing to mention here is that this is PC after all meaning that if you do not like having SteamOS on it you can install Windows instead and so far as we know it will support Windows 11. Now with Windows 11, you will be able to play all of your Steam games and run any kind of Windows software on it including EPIC store, battle.net, and others.

Cost and release date

The initial release date is set for December 2021 and today on July 16^th Valve is opening you can reserve your copy if you want to pre-purchase. Follow this link if you want to reserve your copy. Reserve your Steam Deck device The price of the device will depend on the memory capacity which you would like to have. Please note that each of the 3 offered devices will have the same hardware, the only difference will be in memory available, and the most expensive version will also have anti-glare screen, everything else is identical. 64GB model will be $399, 256GB model will have the price of $529 and largest one with whooping 512GB will be $649

Conclusion

Valve ventures into the digital hardware domain again but it is unsure will they make it this time. Both Steam machine and their controller were in long run failed and later unsupported products so perhaps some customer caution is advised. Although having a handheld PC is tempting I would advise seeing how the overall market will accept this contraption before throwing money into it.

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.
