What You’ll Need

Common Mistakes

• Skipping the Windows Update check, which might leave your system outdated and incompatible.
• Forgetting to run PowerShell as administrator when reinstalling the Microsoft Store.

• Ensure your system date and time are set correctly, as incorrect settings can cause licensing issues.
