Čínská společnost ByteDance, která je majitelem sítě pro sdílení krátkých videí TikTok, bude muset zaplatit v EU pokutu přes 500 milionů eur (12,5 miliardy Kč). Firma nelegálně odesílala údaje o evropských uživatelích do Číny. Evropská komise se chystá udělit pokutu v možné výši přes miliardu dolarů (23 miliard korun) sociální síti X vlastněné Elonem Muskem. Finanční sankce má být prvním velkým trestem za nedodržení nových unijních pravidel, která jsou součástí boje proti dezinformacím a nelegálním příspěvkům na internetu.

Two of the biggest names in artificial intelligence are independently developing new AI tools that encourage learning, at a time when the technology has been criticized for dumbing down smart users in the enterprise and discouraging critical thinking. While the new initiatives from OpenAI and Anthropic are aimed at transforming how AI is used in higher education, the opportunities they open up extend beyond universities.

The approach taken by the two AI firms, emphasizing learning, retention, and critical thinking, has implications for enterprises that are increasingly integrating AI into their workflows.

Such education-focused initiatives arrive at a crucial moment, as research increasingly shows that improper use of AI in workplaces leads to what experts call “cognitive atrophy” — a decline in employees’ ability to think critically when AI handles too many cognitive tasks.

The industry’s approach to keeping quality backups may be masking the importance of other recovery mainstays

Maintaining good-quality backups is often seen as the spine of any organization's ability to recover from cyberattacks quickly. Naturally, given the emphasis placed on them by experts of all stripes, you'd be forgiven for thinking that prioritizing them over anything else would be the way to go.…

Like it or not, those who use Windows Update to obtain and install updates, patches, and fixes will occasionally encounter issues. Sometimes, a specific update may not download. At other times, an update may fail to install. Every now and then, Windows Update (a.k.a. WU) may refuse to interact with the Windows servers from which updates come.

That’s where these steps come into play. Try these troubleshooting techniques in the order outlined below to get WU operational again.

Although I’ve illustrated the WU troubleshooting steps in Windows 11 here, the same techniques also work with Windows 10, with only minor variations. This story covers both Windows OSes quite nicely.

1. If at first you don’t succeed…try again

Though the most basic of all troubleshooting techniques for Windows Update doesn’t always work, it can help sometimes. That is, if WU fails to work as expected, the first thing to try is running the Windows Update request again.

For best results, restart the target PC before trying again. It’s not absolutely necessary, but it may clear some pending or transitory conditions (such as an already-downloaded update that needs to be applied, or some other pending system action) that will put Windows Update back to rights.

Here’s what to do (see Figures 1 and 2):

1. Click Start, then the power button icon (far right), then Restart from its pop-up menu.

Figure 1: After saving all work, click the power button in the Start menu (lower right), and then click Restart in the menu.

2. When the desktop reappears, click Start > Settings > Windows Update, then click the Check for updates button.

Figure 2: Click Start > Settings > Windows Update. Then click Check for updates. It may work!

In my own experience, this works one-quarter to one-half of the time when a WU problem manifests. The upload and install simply succeeds on a second try. Could it have been a download hiccup, or perhaps cosmic rays? Whatever: getting it on that next try is a good thing!

But if restarting the PC provides no relief, move onto the next section.

2. Try the Windows Update troubleshooter (or Get Help app)

As the trite software saying goes, “There’s an app for that.” For common Windows issues — which definitely include WU — it’s equally valid to observe, “There’s a troubleshooter for that.” Troubleshooters are built-in Windows mini-apps meant to diagnose and fix specific Windows problems.

In Windows 11, troubleshooters are being deprecated in favor of a new universal Get Help app, but for now, at least, the Windows Update troubleshooter remains the go-to for WU problems in both Windows 10 and Windows 11. Indeed, if you enter troubleshoot Windows Update errors into the Get Help app, it takes you to this very same troubleshooter.

At some as-yet-unknown point in the future, that troubleshooter may be replaced with another tool available via Get Help. In the meantime, here’s how to fire up the WU troubleshooter directly:

1. Click Start > Settings.

2. Insider the Settings app, type trouble into search. You’ll see something like the list shown in Figure 3 appear. Click Troubleshoot Other problems.

Figure 3: The WU troubleshooter falls under Troubleshoot Other problems.

3. In the “Other troubleshooters” pane, Windows Update appears in position 4 (from top) under the “Most frequent” heading, as shown in Figure 4. Click the Run button at the right-hand side of that entry.

Figure 4: Click the Run button to the right of Windows Update to launch that troubleshooter.

4. The Windows Update troubleshooter runs in its own window. You’ll pick one of two options: I can’t download, install, or uninstall an update or I installed an update, but that update has caused a problem. Pick the one that matches your situation. (For this story, I picked I can’t download…) The troubleshooter asks permission to run an automated diagnostic. Choose Yes, and it runs — be patient, this can take a minute or two.

When it finishes, you’ll see a final report window like the one in Figure 5.

Figure 5: When the error check completes, the troubleshooter asks if its fix worked. How can you tell?

Ed Tittel / Foundry

The troubleshooter asks if its fix solved the problem, but it’s difficult to tell that without running another update check in WU. I usually answer Yes to the question shown in Figure 5, restart the PC, and run Windows Update again. Only then is the real Yes/No answer clear.

In my experience, the WU troubleshooter actually fixes what’s wrong one-third to one-half of the time. If it doesn’t, advance to the next section, please.

3. Completely reset WU

If the WU troubleshooter doesn’t address your issue, there is heavier artillery you can bring to bear. It’s fully described in the excellent Windows 11 Forum tutorial entitled “Reset Windows Update in Windows 11.” This tutorial includes a download link to a special batch file that turns off all WU related services, resets all Windows Update components and policies, then restarts all the services it turns off. (There’s a similar tutorial for resetting WU in Windows 10 on Windows 10 Forums, complete with its own batch file.)

The download ends in a ZIP extension, so you’ll need to unzip it after you download. This will reveal the batch file named Reset_Reregister_Windows_Update_Components_for_Windows11.bat.

Next, you’ll need to open an administrative command prompt or PowerShell session. (Type either cmd or powershell in the Windows search box, right-click Command Prompt or Windows PowerShell in the list of results, select Run as administrator, and enter the password if prompted.)

Next, navigate to the folder where the aforenamed batch file resides. (It’s so handy, I keep it on the desktop on my Windows 10 and 11 PCs, as shown in Figure 6.)

Figure 6: The filename is so long you need to open Properties to see it on the desktop.

Cut and paste the filename into the command line, and then hit the Enter key to run it. That’s all there is to it.

This batch file takes a while to run and involves checking and stopping WU services (bits, wuauserv, and cryptsvc). It then flushes the DNS cache, clears pending update requests, deletes temporary files and folders related to WU downloads, and resets Windows Update policies in the Windows Registry. Then it restarts the services it stopped, and finally ends by offering a Restart button. Use it, because the PC must restart for all these changes to take effect.

I’ve used this batch file on most of my Windows 10 and 11 PCs (and 7, 8, and 8.1 PCs before that), and it’s worked in every case except two to put WU back in action. On the machines where it failed, it turned out I had a hardware problem (a failing SSD) on one of them. On the other, Microsoft’s update was later documented to pose problems for certain PCs.

IMO, the reset-reregister batch file is something of a silver bullet for WU problems. Thus, if you don’t mind waiting the time it can take to work through its processes (under 2 minutes on my 8th-gen i7 Lenovo X12 hybrid tablet), it’s always worth a try.

After I ran it on my first test PC, it cleared the error condition the troubleshooter found but couldn’t fix, and successfully downloaded and installed a pending Cumulative Update (CU).

If the silver bullet doesn’t work, then what?

On one of the two occasions when the batch file didn’t fix WU, I had to take my affected PC to the shop, where they were able to detect and diagnose a failing drive (SSD) that I did not catch on my own. Once that component was replaced, the system returned to normal working order.

On the other machine, I learned from the chatter around KB5053390 on Windows 11 Forum that others were having similar problems. After I used DISM to install that package manually, WU resumed working correctly. Thus, online research can also help prevent unnecessary flailing about when WU problems present.

Before you take a PC that gets to this stage to the shop, I’d recommend trying an in-place repair install. And if that fails, try a clean OS install next. Only then should a trip to the shop be needed. Hopefully, you’ll never get that far!

Additional reading on WU issues and errors

The Microsoft Learn collection called “Windows deployment documentation” covers the ins and outs of Windows deployment, including WU and updates. It includes a Troubleshoot section broken into two parts — namely, “Resolve Windows upgrade errors” and “Windows Update issues troubleshooting.” Both dispense lots of useful advice and techniques, plus discussions of (and references to) Windows Update error codes. For those who want to learn and do more about WU and its workings, these are must-reads.

The Social Security Administration (SSA) payment system has more than 60 million lines of COBOL code. That makes it one of the world’s largest, not to mention oldest, codebases. Everyone agrees it needs to be updated. But, sorry, there’s no way it can be updated in mere months.

Nevertheless, Elon Musk and his “Department of Government Efficiency” (DOGE) claim they can convert the ancient SSA code to Java or some other modern language in only a few months. Reminder DOGE isn’t a real department — and that modernization effort isn’t likely to happen anytime soon.

Seriously, I’ve seen this rodeo before. For example, the Internal Revenue Service (IRS) has been trying to replace the 200,000-line assembly language Individual Master File (IMF) with Java for decades. Hasn’t happened. The latest plan was to replace the IMF by 2028. I say “was” because President Donald J. Trump, Musk, and DOGE have cut the IRS modernization funds to zilch. 

As for SSA, it was going to replace COBOL with Java in 2017, a code translation expected to take five years; it failed. (That’s why we’re having this conversation now.) Part of the problem was due to the COVID-19 pandemic. But, as Ernst & Young noted, the agency also didn’t have a real plan for modernizing its legacy IT systems, nor one to identify and track the systems.

Guess what? There’s no real plan today, either. All we know is that Musk, yes-man Steve Davis and  nine kid software engineers, and some undefined AI program will miraculously transform the code into Java.

I doubt any of them can even read COBOL code. This is, after all, the same crew who thought there were hordes of 150-year-old fraudsters ripping off Social Security. What they didn’t realize was that COBOL doesn’t have a standardized way of dealing with dates, which led to records for numerous century-old-plus people who were not — I repeat- — not getting an unfair penny of government funds.

Why should they know? Over a decade ago, fewer than one in four colleges offered COBOL classes.

Thinking of dates, that’s not the only data in that codebase kept in formats incompatible with modern languages. Converting this data accurately is crucial and fraught with risks. Any errors during the conversion process could result in data loss or corruption, which would have catastrophic consequences for the millions of Americans who rely on Social Security benefits.

Commerce Secretary Howard Lutnick believes that if Social Security checks didn’t go out one month, his mother-in-law “wouldn’t call and complain.” Maybe she wouldn’t — after all, she has a billionaire son-in-law. I don’t. I bet the vast majority of the 73 million other Americans who depend on it don’t have billionaires in the family either. 

Even if these youngsters did grok the language, knowing COBOL is only part of the problem. You see, COBOL is more than just a coding language. It also incorporates organizational processes and policies. That’s not an approach modern developers deal with.

In addition, COBOL systems were not designed to integrate seamlessly with modern technologies. A migration requires extensive customization to ensure compatibility with newer software and hardware, which is both costly and complex. This integration challenge was exacerbated by the need to maintain the system’s functionality during the  transition, a delicate balancing act that demands meticulous planning and execution.

Meticulous is not the word I’d use for Musk and his move-fast and break-things bunch.

As Waldo Jaquith, former director of technology acquisition for the Inflation Reduction Act, said on Bluesky about the scheme, “I’m an expert in modernizing legacy government software systems. This is profoundly stupid and will definitely fail, and it’s just a question of whether our social security system fails along with it.

“I cannot think of a single legitimate reason for DOGE to perform such a modernization, especially on such a time scale.”

Jason Fichtner, a former SSA deputy commissioner, told CNBC: “If you start messing with the system’s code, that could impact those who are currently getting benefits now, and that’s a new front-and-center concern.

“You can’t just flip a switch one night and expect to be able to upgrade. It takes due diligence, and you have to understand the complexity of the programs,” he added.

In light of DOGE’s employee cuts at the agency, Fichtner and Kathleen Romig, director of Social Security and Disability Policy at the Center on Budget and Policy Priorities, warned in a column: “If Social Security’s computer systems experience an outage, which has happened twice in recent years, the agency may lack the expertise to resolve it.” 

Unless Congress acts soon to block DOGE’s misguided technology plans, Social Security, which has never missed a payment in its nearly 90 years, might finally not deliver American workers’ hard-earned retirement checks. Yes, legacy systems should be replaced and upgraded. No one’s arguing they shouldn’t be.

But waving a magic AI wand powered up by a political agenda isn’t the way to do it.
