1. Hardware Compatibility Issues
TPM 2.0 Requirement:
Windows 11 requires Trusted Platform Module (TPM) version 2.0. While many modern systems have TPM 2.0 enabled by default, some may have it disabled in the BIOS or UEFI settings. Users should verify their TPM settings but may find no action is needed.
CPU Compatibility:
Windows 11 supports processors that meet specific design principles around security, reliability, and the minimum system requirements set by Microsoft. While most supported CPUs are Intel 8th-generation and newer or AMD Ryzen 2000 series and newer, there are exceptions. Some processors not classified under these generations, including specific Intel 7th-generation CPUs and embedded or specialised processors (like some Intel Atom, Celeron, and Pentium CPUs), are also supported. It’s best to consult Microsoft’s official list of supported processors for accurate information:

2. Driver Compatibility
In addition to updating hardware drivers (graphics, network adapters, peripherals), users should check for BIOS or UEFI firmware updates from their manufacturers before upgrading. Firmware updates can resolve compatibility issues and enhance system stability during and after the upgrade.
3. Performance Issues
While some users initially reported slower performance after upgrading to Windows 11, others have experienced performance improvements due to optimisations in the new operating system. Performance can vary based on hardware configurations, software compatibility, and whether all system updates have been applied. Recent cumulative updates have addressed many of the initial performance concerns.
4. Software Incompatibility
Initial compatibility problems with virtualisation software like VirtualBox or VMware have been largely resolved through updates from the software vendors. Users should ensure they have the latest versions installed to maintain compatibility with Windows 11.
5. Upgrade Installation Failures
Some installation failures during the initial release of Windows 11 have been mitigated through cumulative updates. Keeping Windows 10 updated before upgrading can reduce the likelihood of encountering these issues.
6. File or Data Loss
No significant changes; backing up data remains a crucial step before upgrading.
7. UI and Feature Changes
Microsoft has reintroduced some features that were initially missing from Windows 11, such as the ability to drag and drop files to taskbar shortcuts. Ongoing updates continue to address user feedback, improving the overall user experience.
8. Security and Privacy Settings Reset
Windows 11 maintains similar telemetry and privacy settings as Windows 10. However, it’s advisable for users to review their privacy settings after upgrading to ensure they align with personal preferences.
9. App Compatibility Issues (Especially for Business Users)
No significant changes; compatibility testing remains important for enterprise environments.
10. Networking Issues
While some users have reported Wi-Fi and Bluetooth connectivity issues post-upgrade, updating network and Bluetooth drivers and installing the latest Windows updates can resolve most of these problems.
