Hi,

Use WIN+R, type winver for the build #.

Answer 2

Try these steps to get Windows Update troubleshooting working and complete the update diagnosis:

1. Run the built-in Windows Update troubleshooter from Settings
   • Windows 10: Select Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters > under Get up and running select Windows Update > Run the troubleshooter.
   • Windows 11: Select Start > Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run.
   • Let it finish, then restart the device and try Windows Update > Check for updates again.
2. If the troubleshooter still will not complete, reset Windows Update components manually
   • Press Win + R, type services.msc, press Enter.
   • Find Windows Update, right‑click > Stop.
   • Open File Explorer and go to C:\Windows\SoftwareDistribution.
   • Delete all files and folders inside SoftwareDistribution.
   • Go back to Services, right‑click Windows Update > Start.
   • Run the Windows Update troubleshooter again from Settings and then check for updates.
3. Check for common causes that block updates
   • Ensure a stable internet connection: Start > Settings > Network & Internet and confirm the device is connected.
   • Make sure there is enough free disk space (at least 16 GB for 32‑bit or 20 GB for 64‑bit when upgrading). If space is low, use the guidance in Free up drive space in Windows from the referenced article.
   • Temporarily disable third‑party antivirus or firewall software, then re‑run the troubleshooter and Windows Update.

If the troubleshooter still fails and updates continue to fail, follow the specific error code guidance in the “Most common Windows Update problems” section of the referenced article (for example 0x80070002, 0x80070003, 0x800705b4, 0x80246007, etc.) and apply the listed steps for that code.
