Check the local network
Written for IT administrators.
Use ping or nslookup to check that the computer can reach other devices on the network and resolve DNS names. If needed, check the Windows Update logs.
If the computer connects directly to Windows Update
Written for IT administrators.
Check that it can connect to the internet. If not, check proxy or firewall configuration and that DNS is working.
Check that Windows is configured correctly to access Windows Update (the page links to the connection endpoint and Delivery Optimization settings articles).
If it uses WSUS and you want a Feature on Demand
Written for IT administrators.
Check the Windows version (for example enter winver in the search bar). Windows 11 22H2 or later, or Windows Server 2025 or later, can continue to the next step. Older versions or Windows 10: the page points to its section on using ISO images or FoD repositories.
If it uses an intranet update service
Written for IT administrators.
For a manual update install (or a FoD on a supported version), check that the computer can connect to the WSUS server. If not, check proxy or firewall configuration and DNS.
Check for blocking policy settings
Written for IT administrators.
Check your Group Policy or policy CSP settings to make sure nothing is blocking updates (the page lists related policy articles).

If these steps do not fix the problem, or you are not sure about a step, stop and get help from Microsoft Support or from the maker of your PC. Stop at once if the data on this computer is at risk: back up your files first, or ask a professional before you go on.
