Microsoft said an artificial intelligence feature on new PCs that captures screenshots and enables search of user activity will be off by default after security researchers determined that attackers could access the underlying data.

The Recall feature was one of the main capabilities Microsoft showed during a press briefing last month for forthcoming Copilot+ PCs with AI computing power onboard.

“If you don’t proactively choose to turn it on, it will be off by default,” Pavan Davuluri, Microsoft’s head of Windows and Surface devices, wrote in a blog post on Friday.

Microsoft has been trying to balance competing interests of late as it moves to incorporate new generative AI tools into its products and to keep up with the competition. While the market is evolving rapidly, user privacy and security are under a microscope. A U.S. government review board recently criticized Microsoft’s handling of China’s breach of U.S. government officials’ email accounts.

Microsoft has already added the Copilot conversational chatbot into Windows in a way that resembles OpenAI’s popular ChatGPT. Both ChatGPT and Copilot rely on servers in the cloud to perform necessary computations and then send back responses to PCs. Recall is different in that it keeps data on users’ computers and doesn’t need to access supplemental computing power over the internet.

Satya Nadella, Microsoft’s CEO, directed employees to put security first and announced changes to its security practices following the U.S. government report.

After Microsoft announced Recall, which can search through a log of previous actions on PCs, industry experts began questioning the potential for hackers to retrieve users’ information.

Security practitioners released software called Total Recall that displays data Recall collects.

“Windows Recall stores everything locally in an unencrypted SQLite database, and the screenshots are simply saved in a folder on your PC,” they wrote in a description of Total Recall on GitHub. They expressed concern about attackers developing tools that can look for usernames and passwords contained in Recall screenshots.

Microsoft is adding security protections to Recall in addition to requiring people to manually turn it on once Copilot+ PCs become available on June 18. The search index database will be encrypted, Microsoft said.

“Windows Hello enrollment is required to enable Recall,” Davuluri wrote. “In addition, proof of presence is also required to view your timeline and search in Recall.”

With Windows Hello, users prove their identity by entering a PIN number, showing their face to the PC camera or providing a fingerprint.

“I think overall having a choice around opting in on home systems will save a lot of people security problems further down the line,” Kevin Beaumont, a former Microsoft cybersecurity analyst who criticized the original implementation of Recall, said in a Friday post on X. “It never should have been enabled by default.”

CNBC Daily Open: U.S. stocks retreat from highs as Broadcom leads tech sell-off

The sell-off in artificial intelligence stocks continued unabated Friday stateside. Broadcom shares tumbled more than 11% as investors grew concerned over lower margins and uncertain deals. Names such as Nvidia, Advanced Micro Devices and Oracle fell in sympathy, which caused major U.S. indexes to close lower.

It was a motif patterning the week. Even though the Dow Jones Industrial Average rose 1.1% week on week on the back of outperformance by financial stocks, tech names dragged down the S&P 500 and the Nasdaq Composite, which fell 0.6% and 1.6% respectively for the week.

That said, investors could have just been jittery amid the narrative of an apparent AI bubble, and were spooked by any sign of bad news. After all, Broadcom’s earnings — as well as its guidance for the current quarter — breezed past expectations.

“Frankly we aren’t sure what else one could desire as the company’s AI story continues to not only overdeliver but is doing it at an accelerating rate,” Bernstein analyst Stacy Rasgon, who has a “buy” rating on Broadcom, wrote in a Friday note.

Future prospects also look rosy, according to UBS. “We expect high profitability and the accelerating impact of the AI, power and resources, and longevity themes to drive 2026 performance,” said strategist Sagar Khandelwal.

But in the near term, investors may still be flighty, unless something concretely reassuring, such as Oracle achieving positive cash flow, reassures them the snapping sound is just a twig in the forest.

Copper could hit ‘stratospheric new highs’ as hoarding of the metal in U.S. continues

Copper prices have hit multiple record highs this year, fueled by supply disruptions and as fears over U.S. tariffs have led to a surge in demand. The rally is set to continue into 2026.

Citi analysts expect prices of the red metal to skyrocket on the back of stronger demand led by the energy transition and artificial intelligence sectors. Electrification, grid expansion and data-center build-outs require large amounts of the metal for wiring, power transmission and cooling infrastructure.

Global week ahead: Europe under fire

U.S. President Donald Trump’s verdict on Europe: a “decaying” group of nations led by “weak” people. His criticism in a recent Politico interview adds to a tough period for the bloc, with challenges on multiple fronts testing European leaders in the final weeks of the year.

This week looks set to be critical, with a high-stakes summit in Brussels and the European Central Bank’s final policy meeting of the year. Key topics for this week include defrosting frozen Russian assets for Ukraine aid; EU vs. U.S. in trade and tech, and updated economic figures at the ECB meeting.
