Despite constant updates, refinements, and promised fixes, Windows 11 still struggles with several persistent problems that frustrate everyday users and IT pros alike.

Windows 11 has matured significantly since its launch, with major feature updates and security improvements rolling out throughout 2024 and 2025. Yet, as we close out December 2025, a surprising number of long-standing issues continue to impact stability, performance, and user experience. Below is a roundup of the 10 most common issues users still face today, why they persist, and what IT teams can do to mitigate them.

File Explorer Still Freezes or Lags

Despite Microsoft’s redesign and performance overhaul, File Explorer remains one of Windows 11’s most problematic components. Users report:

Slow folder loading
Unresponsive right-click menus
Random explorer.exe crashes
High CPU usage when browsing large directories

Even with the latest cumulative updates, File Explorer behaves inconsistently across hardware types, suggesting deeper architectural limitations.

Windows Updates Causing System Slowdowns

Windows Update continues to be a pain point. While reliability has improved, many users still experience:

Longer boot times after updates
High disk usage by Windows Update and TrustedInstaller
Performance degradation on older or mid-range CPUs

Since Windows 11 heavily relies on background servicing, even routine updates can interrupt workflows unexpectedly.

TPM & Secure Boot Errors Persist After Hardware Changes

Windows 11’s strict security requirements—TPM 2.0 and Secure Boot—still confuse many users. A common 2025 complaint:

“Windows can’t verify the device meets security requirements.”

This often appears after BIOS updates, motherboard replacements, or virtualization conflicts. Even IT professionals find the messaging vague and inconsistent.

Wi-Fi Reliability Problems on Certain Chipsets

Some Intel and Realtek Wi-Fi chipsets still suffer from irregular connection drops, especially after system sleep or hibernation. Issues include:

“Connected without internet”
Random disconnects
Slow throughput until Wi-Fi toggle is reset

Microsoft has released partial fixes, but reports continue across forums and enterprise helpdesks.

High Memory Usage by Background Services

Windows 11 aggressively preloads system components to improve responsiveness—yet this often backfires. Users continue to complain about RAM usage exceeding 60–70% even with minimal apps open.

Culprits include:

Desktop Window Manager (DWM)
Windows Widgets
Microsoft Edge WebView2 runtime
SearchIndexer

On low-RAM systems (8GB or less), this becomes especially noticeable.

Search Indexing Still Breaks Easily

Windows Search remains unreliable for many users in 2025. Persistent issues:

Search results appear incomplete
The search bar stops responding
Indexing gets stuck or resets
Cortana removal created indexing inconsistencies in older installs

Enterprise IT teams frequently disable indexing entirely for better stability.

HDR and Multi-Monitor Display Bugs

Microsoft improved HDR handling, yet the ecosystem remains messy:

HDR flickering
Color profile resets
Windows rearranging monitor positions after sleep
Application windows shifting across screens

Gamers and creative professionals feel these bugs the most.

Bluetooth Devices Randomly Disconnect or Fail to Pair

Windows 11 still struggles with Bluetooth stack reliability. Bluetooth LE Audio adoption hasn’t solved everything:

Headsets dropping during calls
Mice/keyboard lag
Devices repeatedly asking to be re-paired

Many affected users note improvements only after switching USB ports or installing OEM-specific drivers.

Start Menu Recommendations & Ads Users Can’t Fully Disable

Even after widespread backlash, Microsoft continues pushing:

App suggestions
Microsoft Store recommendations
Optional ads for services like OneDrive and Copilot

While workarounds exist, there still is no straightforward toggle to fully disable all recommendations. This remains one of the most controversial UI issues.

Copilot Integration Causing Performance and Privacy Concerns

The deep system integration of Windows Copilot (2025 Edition) is powerful, but not without complaints:

Noticeable performance dips when Copilot is indexing or analyzing context
Increased RAM and GPU usage
Users unsure what data is being sent to Microsoft
Occasional failure of Copilot to load after updates

IT admins continue to disable Copilot by Group Policy in sensitive environments.

Conclusion

Windows 11 has evolved into a stable, feature-rich OS — but several persistent issues continue to undermine user experience in late 2025. For IT professionals, these problems mean more support tickets, more troubleshooting time, and more pressure to deploy configuration baselines that bypass Windows’ quirks.

While Microsoft promises ongoing improvements through 2026, many core problems appear rooted in legacy components that are hard to modernize without breaking compatibility.

Until then, IT teams must rely on proactive maintenance, user education, and custom configuration policies to keep Windows 11 environments running smoothly.
