Frequently asked questions

Why would Windows Update get stuck?
Large updates, corrupted cache, conflicting drivers, or a pending restart. Stopping the service and clearing the SoftwareDistribution folder often fixes it.
How long should I wait before fixing a stuck update?
Wait at least 30 minutes. Major feature updates can take an hour or more. If it has not moved for 2 hours, try restarting or clearing the cache.
When should I use the Update Assistant?
When the built-in updater stays stuck after restart and cache clear. The Update Assistant downloads and installs updates directly from Microsoft.
