Microsoft’s ongoing campaign to move Windows 10 users onto Windows 11 continues to spark discussion among enthusiasts, power users, and enterprise IT alike. Recently, the company published an in-depth support article that finally sheds official light on one of the most frustrating parts of the upgrade process: the abrupt upgrade blocks that prevent many systems from transitioning smoothly to the latest OS. These safeguard holds have kept certain devices sidelined for well over a year—even as Windows 11 24H2 nears general availability—leaving many users wondering exactly what’s holding their hardware back, and more importantly, what can be done about it.
Since Windows 11’s debut, Microsoft has tightly controlled the list of devices eligible for upgrade, citing security, stability, and performance as driving reasons. Windows 11’s system requirements, especially the need for TPM 2.0, modern CPUs, and enhanced security features, were controversial from the outset. While Microsoft offers official tools like the PC Health Check app to test eligibility, the explanation for upgrade failures traditionally stopped with a vague error or the now infamous “What needs your attention” notification.
The support article unearthed this year provides a more granular breakdown, spelling out exactly which kinds of incompatibilities may trip up an upgrade attempt. Notably, it’s often not a single issue but a blend of several potential blockers—drivers, hardware deficiencies, application conflicts, or incompatible Windows features—sometimes appearing suddenly after a routine update like KB5001716, which introduces new safeguard logic.
Often, the underlying compatibility scan is being driven by updates such as KB5001716, a quietly-delivered quality update that powers Windows Update's upgrade workflow logic. As of the latest deployments, Microsoft has tweaked this experience: instead of repeatedly pushing the newest feature update, the system now holds back until the blocking issue is resolved, reducing unwanted interruptions for end users.
Windows Insiders, by contrast, may be able to bypass certain blocks for testing purposes, but are warned that this comes with higher risk and little support.
Microsoft is expected to maintain this active safeguard policy throughout Windows 11’s lifecycle, as a means to encourage higher reliability and enforce security baselines critical for modern threats. The tradeoff, for now, is that some legacy hardware will be left behind, even if it’s still functionally capable.

Background: Why Some Windows 10 PCs Can’t Go to Windows 11
Since Windows 11’s debut, Microsoft has tightly controlled the list of devices eligible for upgrade, citing security, stability, and performance as driving reasons. Windows 11’s system requirements, especially the need for TPM 2.0, modern CPUs, and enhanced security features, were controversial from the outset.

Microsoft's Safeguard Holds: How They Work
Windows safeguard holds are automatic blocks Microsoft places on certain hardware or configurations when known compatibility problems could lead to a degraded or unreliable upgrade experience. Instead of allowing a potentially damaging upgrade, Windows signals, often via a notification banner, that “What needs your attention”—inviting, but not mandating, further investigation by the user.Types of Compatibility Issues Flagged
Microsoft outlines several distinct reasons why an upgrade might be paused:- Driver Conflicts: Out-of-date or unsupported drivers can destabilize a system, especially for critical hardware like display adapters, storage, or peripherals.
- Hardware Incompatibility: Not meeting minimal requirements for CPU, RAM, storage, Secure Boot, or TPM modules.
- Application Conflicts: Legacy software or third-party security tools known to cause upgrade failures.
- Incompatible Windows Features: Certain features, roles, or installed updates may block progression if they're recognized as posing issues with Windows 11.
Inside the “What Needs Your Attention” Notification
When users try to upgrade from Windows 10 to Windows 11 on an affected device, Windows Setup may show a prominent banner or popup labeled “What needs your attention.” This notification acts as an early warning, detailing the type of conflict detected. The pop-up doesn’t list every detail—its primary purpose is to halt the upgrade and provide a link to further information.Often, the underlying compatibility scan is being driven by updates such as KB5001716, a quietly-delivered quality update that powers Windows Update's upgrade workflow logic. As of the latest deployments, Microsoft has tweaked this experience: instead of repeatedly pushing the newest feature update, the system now holds back until the blocking issue is resolved, reducing unwanted interruptions for end users.
The Most Common Upgrade Blocks
Analyzing Windows user reports and Microsoft’s breakdown, several upgrade blocks repeatedly surface as the main culprits:1. Outdated or Unsupported Drivers
Manufacturers may not release Windows 11-compatible drivers for older components, particularly graphics, network, and storage controllers. Even if your hardware seems recent, an outmoded driver can prevent the upgrade. Devices with bespoke or enterprise-deployed drivers are especially at risk.2. “Legacy” or Incompatible Hardware
Some CPUs, even from within the last five years, don’t make the Windows 11 compatibility cut—especially those lacking hardware-based security features. Laptops without TPM 2.0, or desktops with Secure Boot disabled, are commonly blocked.3. Certain Third-Party Applications
Security software, custom system utilities, or virtualization tools might be flagged as incompatible if they’re known to interfere with the upgrade process. Sometimes, even uninstalling the application isn’t enough—residual drivers or services can persist and must be manually cleaned.4. Problematic Windows Features and Updates
Some Windows features or roles, such as certain language packs, custom shell environments, or legacy compatibility layers, may need to be uninstalled or updated before proceeding. Rarely, the presence of specific updates or unique domain policies can be the root cause.Navigating Safeguard Holds: What Users Can Do
Microsoft’s updated support guidance doesn’t leave users in the dark. The company outlines a series of steps users can attempt to resolve the block:- Update Drivers: Use Windows Update, OEM support tools, or component manufacturers’ websites to obtain the latest drivers.
- Disable or Uninstall Problematic Applications: Remove third-party antivirus or system optimization tools that are known to cause issues.
- Ensure Hardware Compatibility: Double-check requirements—TPM 2.0, Secure Boot, supported CPU generation, adequate RAM and storage—against Microsoft’s published lists.
- Remove or Update Windows Features: Uninstall optional features, language packs, or custom shells temporarily.
- Apply All Windows Updates: Sometimes the only fix is receiving the next bug-fixing patch from Microsoft or the hardware vendor.
Insider and Enterprise: A Distinct Experience
Enterprise IT administrators get slightly different treatment, with more granular reporting available through management consoles and greater control via Group Policy and Windows Update for Business settings. For business-critical deployments, safeguard holds are a blessing, lowering risk when rolling out operating system upgrades at scale.Windows Insiders, by contrast, may be able to bypass certain blocks for testing purposes, but are warned that this comes with higher risk and little support.
Transparency and Trust: Microsoft’s Changing Approach
One of the most positive shifts in Microsoft’s approach is greater transparency around upgrade blocks. The new support article marks a move away from cryptic error codes towards clear, actionable explanations. However, challenges remain—many users still report frustration at receiving what appears to be catch-all messages, or experiencing lengthy hold times with little direct feedback on exactly which driver, feature, or policy is at fault.Potential Risks and Downsides
While these compatibility checks prevent disastrous updates, they aren’t without downsides. The most notable risks include:- False Positives: Overly conservative checks may block upgrades unnecessarily, especially when third-party software or policies are misdiagnosed as critical risks.
- Stagnation: Owners of hardware just beneath the cutoff are forced to remain on Windows 10, which is already nearing end of support.
- Fragmentation: Device fleets may become split between Windows 10 and Windows 11, complicating management and support.
Windows 11 24H2 and the Evolving Block List
As Windows 11 24H2 rolls out, Microsoft continues to fine-tune its safeguard hold system. Recent months have seen several longstanding upgrade blocks resolved, allowing a new wave of previously-stuck devices to move forward. But as new features and hardware requirements arrive, the block list stays fluid—users must regularly check for driver, firmware, and Windows updates.Microsoft is expected to maintain this active safeguard policy throughout Windows 11’s lifecycle, as a means to encourage higher reliability and enforce security baselines critical for modern threats. The tradeoff, for now, is that some legacy hardware will be left behind, even if it’s still functionally capable.
The Path Forward: Advice for Upgraders
For anyone still seeking the upgrade path from Windows 10 to 11, a methodical approach remains best:- Consult Microsoft’s official lists for compatible processors and minimum hardware specs.
- Use PC Health Check or similar diagnostics tools for early detection of potential issues.
- Proactively update all drivers and firmware from the manufacturer’s support site, not just through Windows Update.
- Review and, if needed, temporarily disable or uninstall security suites and non-essential utilities.
- Monitor Microsoft's support channels and the community for emerging issues and newly-resolved blocks.
Conclusion
Microsoft’s expanded documentation on upgrade blocks offers much-needed clarity as Windows 10 approaches its sunset years. By detailing the real-world reasons behind safeguard holds—from drivers and hardware to applications and features—the company empowers users to take corrective steps where possible. Still, the tradeoffs are real: some users will face inevitable hardware dead ends, and the ever-changing block landscape means vigilance is necessary. As Windows 11 24H2 and future updates arrive, expect this system of blocks and gradual removals to define the upgrade journey for millions—striking a challenging balance between seamless user experience and the uncompromising demands of security and reliability in the modern PC era.Source: Neowin Microsoft lists reasons why your PC is blocking Windows 10 upgrades to Windows 11
