What you’re seeing
- Windows Update shows 'Downloading - 0%' for hours without moving.
- An update sits at 'Installing - 100%' and never asks for a restart.
- The progress percentage resets to zero after a restart and gets stuck again.
- Checking for updates spins indefinitely and never returns a result.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The local update download cache is corrupted, so Windows keeps trying to use damaged files.
- The Windows Update or Background Intelligent Transfer services are hung and not processing work.
- The PC is low on free disk space, so the download or installation can't finish.
- A proxy, firewall or content filter blocks or slows the connection to Microsoft's update servers.
- The component store that Windows uses to install updates is damaged.
- The network connection is marked as metered, which pauses or limits update downloads.
Why it matters
A PC that can't finish installing updates falls behind on security fixes while appearing to be 'working on it', so the gap often goes unnoticed. The stuck process can also slow the computer, block shutdowns or trigger an unexpected restart at a bad time. When several machines stall at once, it's often a network or policy issue that also leaves the rest of the office exposed.

Frequently asked questions
Should we keep waiting, or is it really stuck?
Large updates can legitimately take a while, but no progress for several hours usually means something is wrong. An engineer can tell from logs whether the update is moving or stuck.
Is it risky to restart while it says 100%?
Interrupting an active installation can cause problems, so it's better to confirm what Windows is actually doing first. We check that before making any changes.
