    When Should You Consider a Windows Reinstall?

    A Windows reinstall or repair is sometimes the most effective solution for a computer that is behaving erratically, running slowly despite hardware upgrades, or failing to start. Common situations where our technicians recommend a Windows reinstall or repair include persistent blue screens, update failures, corrupted system files, virus damage, and unexplained performance degradation.

    Before reinstalling Windows, we attempt to back up your files and data where possible. We discuss the available options including repair installs that preserve your files, factory resets, and clean installations, and help you choose the approach that best fits your situation.

    • Persistent boot loops or blue screens
    • Windows Update failures
    • Severe virus or malware damage
    • Corrupted system files
    • Upgrading to a new hard drive or SSD

    Windows 11

    Windows 11 Upgrade Service

    Upgrading to Windows 11 requires hardware that meets Microsoft's minimum requirements. We check compatibility and handle the full upgrade process.

    Compatibility Check

    We verify that your CPU, RAM, storage and TPM meet Microsoft's Windows 11 requirements before starting.

    Data Backup

    We back up your important files before the upgrade to protect against unexpected issues.

    Upgrade Execution

    We perform the full Windows 11 upgrade including system configuration and post-upgrade settings.

    Driver Updates

    We update drivers for your hardware to ensure everything works correctly after the upgrade.

    Software Verification

    We check that your key applications are running correctly on Windows 11 after the upgrade.

    Performance Check

    We verify startup times, responsiveness and functionality before returning your computer.

    Not all computers are eligible for Windows 11. If your device does not meet requirements, we discuss alternatives including optimizing Windows 10 or hardware upgrades where applicable.

    Windows Installation FAQ

    It depends on the method used. A repair install or reset with the 'keep my files' option can preserve personal data. A clean install will remove everything. We discuss your options and back up data where possible before proceeding.
