Microsoft has officially launched its highly debated Windows Recall feature, a flagship AI-powered tool exclusive to Copilot+ PCs, as part of the April 2025 Windows non-security preview update. Announced nearly a year ago in May 2024, Recall has sparked significant controversy due to its privacy and security implications, leading to multiple delays and extensive revisions before its public release on April 25, 2025.
What is Windows Recall?
Recall is an AI-driven feature designed to enhance productivity by creating a “photographic memory” of user activity on Copilot+ PCs. It continuously captures screenshots of a user’s screen—every few seconds—covering apps, websites, documents, and more. These snapshots are stored locally in an encrypted, searchable database, allowing users to revisit past activities using natural language queries. For instance, a user could search for “the dress I saw online last week” and Recall would retrieve the relevant screenshot, enabling quick access to the webpage or document.
The feature leverages the neural processing units (NPUs) in Copilot+ PCs, a new category of Windows devices powered by Qualcomm Snapdragon, Intel, or AMD processors, designed to handle AI tasks locally without relying on cloud processing. Microsoft highlights that Recall’s data is not shared with the company or third parties and is protected by Windows Hello authentication, requiring biometric or PIN verification to access the database.
A Rocky Road to Release
Recall’s journey to market has been fraught with challenges. Initially unveiled at Microsoft’s Build conference in May 2024, the feature was met with immediate backlash from security experts and privacy advocates. Critics labeled it a “privacy nightmare,” pointing out that the original design stored screenshots in plain text, making them vulnerable to unauthorized access by hackers or other users on the same device. Cybersecurity researcher Kevin Beaumont demonstrated that the data could be extracted with just two lines of code, raising alarms about its potential misuse in scenarios like intimate partner violence or corporate espionage.
Due to these concerns, Microsoft delayed Recall’s launch, originally planned for June 2024 alongside the first Copilot+ PCs. The company shifted its approach, making Recall an opt-in feature rather than enabled by default and implementing significant security overhauls. These included encrypting data at rest, adding automated content filters to exclude sensitive information (such as passwords or credit card numbers), and requiring frequent Windows Hello reauthentication. A limited preview was released to Windows Insiders in November 2024, followed by broader testing in the Release Preview channel earlier this month, culminating in the current rollout.
“Recall (preview) saves you time by offering an entirely new way to search for things you’ve seen or done on your PC securely,” Microsoft stated in a blog post. “With the AI capabilities of Copilot+ PCs, it’s now possible to quickly find and get back to any app, website, image, or document just by describing its content.”

Privacy and Security: Are Concerns Addressed?
Microsoft claims that the updated Recall is now “the most secure experience in Windows,” according to security executive David Weston. The company has introduced several safeguards to address initial criticisms:
- Opt-in Requirement: Users must explicitly enable Recall during setup, and it can be paused or disabled at any time through the Privacy & Security settings.
- Local Processing: All data is processed and stored on the device, with no cloud transmission.
- Content Filtering: Automated filters aim to exclude sensitive data, though testing by outlets like Ars Technica suggests these filters remain inconsistent.
- Storage Allocation: On SSDs with 1TB or more, Recall reserves 150GB for snapshots, with customizable retention settings.
Despite these measures, skepticism persists. Privacy advocates argue that the feature’s very nature—capturing screenshots every three seconds—poses inherent risks, particularly for users who may not fully understand its implications. Posts on X have compared Recall to “spyware,” with some users expressing discomfort at the idea of their activities being recorded, even locally. Others worry about the feature’s appeal to threat actors, who could exploit Recall’s database if they gain access to a device.
Availability and Limitations
Recall is exclusive to Copilot+ PCs, which require at least 16GB of RAM, 256GB of storage, and device encryption. This limits its availability to a small fraction of Windows users, as most PCs sold before mid-2024 lack the necessary NPU hardware. The feature is currently optimized for English, Chinese (Simplified), French, German, Japanese, and Spanish, with a gradual rollout planned for most markets. Users in the European Economic Area will have to wait until later in 2025 due to regulatory considerations.
Alongside Recall, Microsoft is introducing other AI-powered features, such as Click to Do, which offers context-sensitive suggestions (e.g., copying text or reopening documents), and an enhanced AI search capability. However, some features, like Click to Do, are initially limited to Arm-based Copilot+ PCs, with x86-based systems (Intel and AMD) gaining support later.

Public Reaction and Future Implications
The public response to Recall’s release remains mixed. While some users praise its potential to streamline workflows—particularly for those who struggle to recall where they saw specific content—others remain wary of its privacy trade-offs. On X, sentiments range from cautious optimism to outright rejection, with one user noting, “How would you feel if your computer took screenshots every 3 seconds on its own?”
Microsoft’s decision to make Recall opt-in and removable has been welcomed as a step toward transparency, but critics argue it should be a separate app rather than a core OS feature. Enterprise users, in particular, may disable Recall by default, reflecting broader concerns about data security in professional settings.
As Microsoft pushes to integrate AI deeply into Windows, Recall represents a bold but risky bet. Its success will hinge on whether users perceive its productivity benefits as outweighing its privacy costs. For now, the feature remains in preview, giving Microsoft time to gather feedback and refine it further. Whether Recall becomes a cornerstone of the Windows experience or a cautionary tale of AI overreach remains to be seen.
