Microsoft Confirms Windows Update Locking PCs Or Blue Screen Of Death — How To Fix
Updated May 20 with details of how Microsoft has now fixed the bug and what you should do.
Windows 10 users have recently come across a problem caused by the latest Windows 10 KB5058379 update. The problem is, it's a mandatory update. Now, Microsoft has issued a critical update to put things right. Full details of what you should do at the end of this post.

First, some history. The issue was reported on May 15 by Windows Latest. 'Windows 10 KB5058379 is causing PCs to boot into Windows Recovery and require BitLocker key. Windows Latest received reports that KB5058379 install starts, but ends up at 'Enter the recovery key to get going again (Keyboard layout: US)' screen, and there's a text field to add the recovery key. In some cases, there's a BSOD as well," Windows Latest said.
It's unusual for BitLocker recovery to trigger automatically unless we make a change to the hardware or BIOS settings. Several users told Windows Latest that a BitLocker Recovery (Windows Boot Recovery) is prompted automatically after installing KB5058379, which is rolling out via Windows Update. In some cases, there's a BSOD as well… Windows 10 KB5058379 is a mandatory security update rolling out for everyone, including businesses or enterprises, and you don't have a choice but to install the update,' it went on.
If you aren't familiar with BitLocker, then, as you'll see below, there's a chance that the problem won't apply to you. Anyway, here's how Bleeping Computer described the issue and how it manfests.
'The BitLocker Windows security feature encrypts storage drives to prevent data theft, and Windows computers typically enter BitLocker recovery mode after events like TPM (Trusted Platform Module) updates or hardware changes to regain access to protected drives. Today, Microsoft confirmed the issue and said it's investigating reports that 'a small number' of Windows 10 PCs display BitLocker recovery screens after installing the KB5058379 update,' it said.
On Saturday, May 17, Microsoft updated a support document to acknowledge the issue. 'We are aware of a known issue on devices with Intel Trusted Execution Technology (TXT) enabled on 10th generation or later Intel vPro processors,' it said. It also shared some good news.
'Consumer devices typically do not use Intel vPro processors and are less likely to be impacted by this issue. This issue ONLY applies to the affected platforms listed below. Windows 10, versions 22H2; Windows 10 Enterprise LTSC 2021, Server: None,' Microsoft said in its support document.
Again, this is why you'll probably know about BitLocker if there's a chance you could be affected.
So, if you have a PC with Intel vPro chip, you could be tempted not to install it yet, though since it's mandatory, it's not advisable to skip it.
Take heart, though: Microsoft is working on it. 'We are urgently working on a resolution for this issue, with plans to release an Out-of-band update to the Microsoft Update Catalog in the coming days,' it says, and the fact that the latest support document was filed on a Saturday indicates the urgency.
The first stage, obviously, is to find your 48-digit Bitlocker recovery key. Here are Windows Latest's helpful instructions for what you need to do.
You need to reboot into BIOS/UEFI, which can be done by pressing a key after power-on, but the keys are different across all OEMs. On most Dell/HP/Lenovo: press F2, F10/F12, or Esc immediately after power-on to enter BIOS/UEFI.
Next, in BIOS, look for Security, open Virtualization or Advanced CPU Settings and turn off Intel TXT. This could also be referred to as Trusted Execution, or OS Kernel DMA Support. Note that you can leave VT for Direct I/O (or VT-d) enabled. Finally, save changes and exit BIOS.
'The idea is to disable Intel TXT / Trusted Execution and allow KB5058379 to finish installation. If you followed the steps correctly, you won't run into BitLocker Recovery or BSOD. Remember that the BSOD or BitLocker is triggered when installing KB5058379, but you won't have the issue after the update is installed successfully. The catch is that it's a challenge to install the security patch without turning off Intel TXT / Trusted Execution in BIOS,' Windows Latest explains.
Windows 11 is not affected by this issue, it seems.
So, how about that update to fix things? Microsoft said it was working urgently and would release an update in days. It did, just 48 hours after it acknowledged the flaw.
On Monday, May 19, Microsoft said it had resolved the problem. 'We are aware of a known issue on devices with Intel Trusted Execution Technology (TXT) enabled on 10th generation or later Intel vPro processors. On these systems, installing the May 13, 2025, Windows security update (KB5058379) might cause lsass.exe to terminate unexpectedly, triggering an Automatic Repair. On devices with BitLocker enabled, BitLocker requires the input of your BitLocker recovery key to initiate the Automatic Repair,' it said.
Then it described the resolution, with an update that is only available to download through the Microsoft Update Catalog, so that's the place you need to visit to sort this.
'This issue was resolved in the out-of-band (OOB) update KB5061768, which is only available via the Microsoft Update Catalog. If your organization uses the affected platforms and hasn't yet deployed the May 13, 2025, Windows security update, or if KB5058379 failed to install, we recommend you apply this OOB update instead,' it said.
If you have already installed the updated and are unable to start your PC, you need to disable Intel VT for Direct I/O (also known as VTD or VTX) and Intel Trusted Execution Technology (TXT) in your BIOS / UEFI settings. This disabling should only be temporary. You'll need to enter your BitLocker recovery key. If you don't have that, see the instructions to retrieve the key.
Once you've done that, go to the Microsoft Update Catalog and install the new update, KB5061768.
Then restart Windows and return to your BIOS / UEFI settings. This is when you re-enable Intel VT for Direct I/O (also known as VTD or VTX) and TXT. (Note that you'll again need your BitLocker recovery key for this step.

Windows parental controls are crashing Chrome — here's the workaround
Windows 11's Family Safety feature is supposed to block certain websites from children, but apparently it's also been causing issues with Google's Chrome browser, a (vastly more popular) competitor to Microsoft's own Edge. The problem first surfaced on Windows on June 3, per The Verge, when several users started noticing they couldn't open Chrome or their browser would crash randomly. Restarting their computer or reinstalling Chrome didn't fix the issue, and other browsers like Firefox and Opera appeared unaffected. On Monday, a Google spokesperson posted in the company's community forum that it had investigated these reports and found the issues were linked to Microsoft's new Windows Family Safety feature. This optional feature is primarily used by parents and schools to manage children's screen time, filter their web browsing, and monitor their online activity. Curiously, the bug has been going on for weeks now, and Microsoft still hasn't issued a patch. 'We've not heard anything from Microsoft about a fix being rolled out,' wrote a Chromium engineer in a bug tracking thread on June 10. 'They have provided guidance to users who contact them about how to get Chrome working again, but I wouldn't think that would have a large effect.' While this issue could be an innocent bug, Microsoft has a history of placing annoying hurdles between Edge and Chrome to entice users to stick with its browser. So anytime a technical snafu makes Chrome run worse on Windows PCs, Microsoft understandably gets some serious side eye. Thankfully, there seem to be two ways to get around this bug while we wait for Microsoft to issue a fix, and they're both fairly simple. The most straightforward is to turn off the "Filter Inappropriate Websites" setting. Head to the Family Safety mobile app or Family Safety web portal, select a user's account, and choose to disable "Filter inappropriate websites" under the Edge tab. However, that'll remove the guardrails on Chrome and let your child access any website, including the ones you were trying to block in the first place. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. If you want to keep the guardrails on and still use Chrome, some users reported that altering the name in your Chrome folder (to something like Chrome1, for example), got the browser to work again even with the Family Safety feature enabled.

AMD Is Gunning for Nvidia's AI Chip Throne. Should You Buy AMD Stock Now?
For the longest time, Nvidia (NVDA) has enjoyed an open runway in the data center and artificial intelligence GPU market. But on June 12, Advanced Micro Devices (AMD) made it clear that it was no longer content staying in the shadows. In a detailed reveal, the company introduced its upcoming Instinct MI400 series, a new breed of AI chips set to launch next year. 3 Highly-Rated Dividend Stocks You've Probably Never Heard Of (But Should) AMD Just Landed a New Microsoft Partnership. Should You Buy AMD Stock Here? The Crypto Rally Is 'Just Getting Started' According to Analysts. Buy Coinbase Stock Here. Get exclusive insights with the FREE Barchart Brief newsletter. Subscribe now for quick, incisive midday market analysis you won't find anywhere else. These chips form the core of a larger vision called Helios, a full server rack capable of connecting thousands of chips into one powerful 'rack-scale' system. That architecture puts AMD head-to-head with Nvidia's Blackwell platform, which links together 72 GPUs in a single configuration. AMD also drew a line in the sand on inference performance. Its new chips come with more high-speed memory, making it possible to run massive AI models on a single GPU. As anticipation builds, let us see how high this can take the AMD stock. Advanced Micro Devices (AMD), based in Santa Clara, California, has carved out a formidable presence in the high-performance computing landscape with a market cap of $205.6 billion. AMD delivers one of the industry's most comprehensive portfolios of advanced processor technologies. In the last three months alone, AMD's stock has gained 22.5%, significantly outpacing the broader S&P 500 Index ($SPX), which rose by 5.4% in the same period. Currently, AMD trades at 40.2 times forward earnings and 8 times its sales. Both metrics sit below the five-year historical average. This signals a potential window for investors looking for exposure to the next wave of computing innovation. On May 6, Advanced Micro Devices stepped into the earnings spotlight and delivered a performance that raced ahead of Wall Street expectations. In its Q1 2025 results, the company posted revenue of $7.4 billion, marking a 35.9% increase from the same quarter last year and sailing past Wall Street's forecast of $7.1 billion. The showstopper in this story was AMD's data center segment, which pulled in $3.7 billion, registering a 57.2% year-over-year surge. The client and gaming segment brought in $2.9 billion. While the gaming unit struggled under pressure, sliding 29.8% to $647 million, the client business rose sharply, climbing 67.7% to reach $2.3 billion. The divergence between segments did not go unnoticed, yet the weight of the gains was strong enough to lift AMD's overall gross margin to 50%, up from 47% a year earlier. A stronger product mix and swelling demand for data center chips provided a firm foundation for this margin expansion. On the profit front, the company kept up its winning streak. Non-GAAP net income jumped 54.6% to touch $1.6 billion. Adjusted EPS also moved 54.8% higher, landing at $0.96 and ahead of analyst expectations of $0.93. In addition, AMD generated $939 million in cash from operations, while free cash flow for the quarter stood at $727 million. Peering into the second quarter of 2025, management expects revenue to hover around $7.4 billion, plus or minus $300 million. This includes a projected $700 million revenue reduction stemming from a new export license affecting MI308 shipments to China. Still, the midpoint implies 27% growth over the previous year. Analysts, however, expect some softness in profitability for the Q2 2025, projecting a 30% decline in EPS to $0.35. Yet the broader picture remains encouraging. For the full fiscal year 2025, the bottom line is expected to climb 20.6% from the previous year to $3.16. Looking further ahead, fiscal year 2026 is forecast to deliver even stronger growth, with EPS projected to rise 54% to reach $4.87. AMD holds its ground with quiet conviction, earning a 'Moderate Buy' consensus that reflects solid confidence from the analyst community. Among the 42 analysts tracking the stock, 28 issue a 'Strong Buy,' one backs a 'Moderate Buy,' and 13 advise to 'Hold.' The average price target of $133.32 represents potential upside of 5.5%. The Street-high price target of $200 implies shares could gain nearly 60% from here.

Bernstein SocGen Lifts MSFT Target to $540 on AI-Driven Cloud Outlook
Bernstein SocGen has raised its price target on Microsoft (NASDAQ: MSFT) to $540 from $520, and kept an Outperform rating for the stock a couple of weeks ago. Shares are trading at $477, near their 52-week high, with a market cap of $3.55 trillion. The firm sees longer-term upside tied to Microsoft's partnership with OpenAI. If OpenAI's roadmap unfolds as projected, Azure stands to capture a sizable share of the resulting demand, particularly in cloud infrastructure. Bernstein believes this could materially boost Microsoft's top line by 2029–2030. Image by Tawanda Razika from Pixabay To account for this, the analysts raised their revenue forecast for FY27 and increased earnings estimates for FY26 and FY27. They've also bumped Microsoft's valuation multiple from 28.5x to 29.5x. Most of the expected gains fall outside the near-term forecast window, but the analysts argue the long-range potential is strong enough to justify the upward adjustment. Azure's position in the AI supply chain remains central to that view. While we acknowledge the potential of MSFT as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.
