Windows Update Stuck or Failing —
How to Unstick It

A stuck update is almost never a broken computer

Windows updates matter — they’re how your computer gets its security patches, the locks on your digital doors. But when one jams, the messages Windows shows you are scary out of all proportion: frozen percentages, “undoing changes made to your computer,” error codes that look like license plates. Most of it is fixable at the kitchen table, with patience and a short list of steps done in the right order.

The order matters. The gentle fixes — a real restart, a disk-space check, Microsoft’s free built-in troubleshooter — solve most stuck updates before the serious-sounding steps are ever needed. This page gives you that list. The 25-page PDF goes deeper: reading the frozen screen, decoding error codes, the advanced cache reset, and the fake-update scams to steer around.

Step 1 — The fix that works more than all others combined

1. Save your work, click Start, then the power button, then Restart — not Shut down. (Shut down uses a shortcut that doesn’t fully clear the slate; Restart does.)
2. When it comes back, open Settings > Windows Update and click Check for updates.
3. If it asks for a restart, do it right away — don’t leave it for “later.”
4. Laptop? Plug it in and leave the lid open while it works.

Step 2 — Check the four quiet blockers

• Disk space: Settings > System > Storage. Less than about 10 GB free is very likely your whole problem — big updates need room to unpack.
• Internet: open a web page. If it won’t load, fix the connection first.
• Power: plugged in, not running on battery fumes.
• The clock: a wrong date can break the secure connection updates use. Settings > Time & language > turn “Set time automatically” on.

Step 3 — Run the free built-in fixer

1. Click Start, type Get Help, and open the Get Help app.
2. Search for windows update troubleshooter and follow the prompts — it finds and fixes the common causes automatically.
3. Or go through Settings: System > Troubleshoot > Other troubleshooters, then click Run next to Windows Update.
4. Restart afterward and check for updates again.

Stuck on the blue “Working on updates” screen?

• Spinning dots, fan noise, or a number that’s moved at all in the last hour = it’s working. Leave it alone.
• Big updates can take an hour or more on older machines — and the percentage isn’t a clock. Sitting at 30% for 40 minutes, then leaping ahead, is normal.
• My rule: give it two to three hours (or overnight) before declaring it frozen.
• Truly frozen? Note the number, hold the power button about ten seconds until it’s off, wait thirty seconds, and turn it back on. Windows usually finishes the job or safely backs it out on its own.

“Undoing changes made to your computer” — don’t panic

• This screen is a safety net, not a disaster. The update hit a snag and Windows is putting everything back the way it was.
• Let it finish completely — cutting power during the undo is as risky as cutting it during the update.
• Your photos, documents, and programs are not part of the rollback. It only touches Windows’ own files.
• Afterward: write down any error code, run the troubleshooter, and retry once. Many updates succeed on the second attempt.

If the same update fails week after week

• Write down the exact error code — it’s a clue, not a verdict. 0x80070070, for example, usually just means the disk is too full.
• Look codes up on support.microsoft.com only — fake “fix your error” websites love update codes.
• Try the patient rhythm: install, restart every time it asks, check again — repeat until “You’re up to date.” Two or three rounds is normal after a backlog.
• Still stuck? Pausing updates for a week (Settings > Windows Update > Pause updates) often lets Microsoft fix its end — then retry fresh.
• The last resort is the update-cache reset (the SoftwareDistribution deep clean). It’s safe done right, and it’s in the PDF — but it’s also a perfectly good reason to call me instead.

One thing that’s never a real update

• A web page that fills your screen shouting “Windows update required — call this number” is a scam, every time. Real updates never appear in your browser and never show a phone number.
• Microsoft doesn’t call you about updates. Ever. Hanging up mid-sentence is allowed.
• Real Windows updates happen in exactly one place: Settings > Windows Update. They never cost money and never take gift cards.

What's in the 27-page PDF

• What Windows is actually doing during an update — the three phases, in plain English
• The 60-second version: the whole method in six checkboxes
• “Five flavors of stuck” — a table to identify exactly which problem you have
• The “don’t turn off your computer” rule — when it’s real and when it isn’t
• The gentle fixes: restart-and-retry, disk space, and the built-in troubleshooter (both paths)
• Reading the frozen percentage screen — and the careful forced restart, step by step
• “Undoing changes made to your computer,” fully explained
• Common error codes decoded: what they usually mean and what to try first
• The pause button and Active hours — updates on your schedule, not Microsoft’s
• The advanced deep clean: resetting the update cache safely (or knowing when to hand it off)
• The fake-update scams — pop-ups, phone calls, and phony blue screens, calmly dismantled
• A tape-to-the-refrigerator checklist, kitchen-table Q&A, plain-English glossary, and a fill-in trouble log

Why I wrote this

I write these guides as printable handouts for the same folks I visit around Portage County — because a stuck update always seems to happen on a Sunday evening, right when nobody’s office is open. The steps in this one are the same ones I do on house calls, in the same order. Most people never need me for this. And if you do — the frozen screen, the repeating code, the deep-clean reset — it’s a $99 flat visit with a 30-day follow-up, and I’ll show you what I’m doing as I go. — Bill
