Summary: Blue screen, no boot, or broken Start after Patch Tuesday? Uninstall the last update, roll back Windows 11, and use recovery when the PC won't start.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
Everything worked until Windows Update rebooted the machine. Now you have a [blue screen](https://www.mytechnician.tech/tips/how-to-fix-bsod-blue-screen/), a [black screen](https://www.mytechnician.tech/tips/fix-black-screen-on-boot-windows-11/), a [Start menu that will not open](https://www.mytechnician.tech/tips/fix-windows-11-start-menu-not-opening/), or a PC that [will not shut down](https://www.mytechnician.tech/tips/fix-windows-11-not-shutting-down-restarting/). You want the last good build back—not a wipe.

## First: Identify What Actually Installed
Knowing which update landed tells you what to remove and how much time you have.

1. **Settings** → **Windows Update** → **Update history**.
2. Note the **KB number** and date of the most recent entry, and whether it was a **quality update** (monthly, KB number) or a **feature update** (a version change such as 23H2 → 24H2).
3. Check your current build: `Win + R` → `winver`.

Also check whether a **driver** came down at the same time—Windows Update frequently ships graphics and network drivers alongside patches, and the driver is the culprit more often than the patch.

## If Windows Still Boots

### Option 1: Uninstall the Quality Update
The fastest fix, and the right one in most cases.

1. **Settings** → **Windows Update** → **Update history** → **Uninstall updates**.
2. Find the most recent **Security Update** or **Cumulative Update for Windows 11**.
3. Click **Uninstall** and restart.

Then **pause updates** for a week so Windows does not immediately reinstall the same patch: **Settings** → **Windows Update** → **Pause updates**.

### Option 2: Go Back to the Previous Version (10-Day Window)
Only for a feature update, and only within about ten days.

1. **Settings** → **System** → **Recovery**.
2. Click **Go back** under **Previous version of Windows**.
3. Choose a reason, continue, and keep a laptop on AC power.

**Greyed out?** The ten days have passed, or Disk Cleanup removed the `Windows.old` folder. Use one of the other options.

### Option 3: System Restore
`Win + R` → `rstrui` → choose a restore point dated **before** the update → finish.

This fails if System Protection was off—which it is by default on many installs. Turn it on now for next time: [create and use a system restore point](https://www.mytechnician.tech/tips/create-system-restore-point-windows-11/).

### Option 4: Roll Back Just the Driver
If a display or network driver arrived with the patch, this is often the whole fix and keeps the security update in place.

**Device Manager** → the device → **Properties** → **Driver** → **Roll Back Driver**. If it is greyed out, install the previous version manually from NVIDIA, AMD, Intel, or your laptop maker.

## If Windows Will Not Boot

### Reach the Recovery Environment
Force-shutdown at the logo three times by holding the power button. On the next boot Windows opens **Automatic Repair** → **Advanced options**.

From a working sign-in screen you can instead hold **Shift** while clicking **Restart**.

### Uninstall the Update Offline
**Troubleshoot** → **Advanced options** → **Uninstall Updates** → **Uninstall latest quality update**. Try **Uninstall latest feature update** only if the quality update option does not apply or does not help.

This works without booting Windows and is the single most useful recovery option after a bad patch.

### Or Work From Safe Mode
**Advanced options** → **Startup Settings** → **Restart** → press **4**. From there, uninstall the update in Settings, remove the driver in Device Manager, or run System Restore. See [how to enter Safe Mode](https://www.mytechnician.tech/tips/how-to-enter-safe-mode-windows-11/).

### Startup Repair
**Troubleshoot** → **Advanced options** → **Startup Repair**. This addresses boot configuration rather than the update itself, but it is worth one pass when the machine will not start at all.

## Stopping It Coming Straight Back
Windows will attempt to reinstall the update you just removed, often within hours.

1. **Pause updates** immediately after the rollback.
2. Download Microsoft's **Show or hide updates** troubleshooter (`wushowhide.diagcab`), run it, choose **Hide updates**, and tick the specific KB.
3. Search the KB number plus "known issues" on Microsoft's release health page—if the problem is widespread, Microsoft usually publishes a fix or a Known Issue Rollback within days.

## If Every Update Fails or Rolls Back
The update stack itself is damaged rather than the specific patch being bad. Clear the cache and repair the component store: [Windows Update stuck](https://www.mytechnician.tech/tips/fix-windows-update-stuck-windows-11/) and [fix common Windows 11 update errors](https://www.mytechnician.tech/tips/fix-windows-11-update-errors/).

## When Rollback Is Not Enough
1. **Reset this PC** → **Keep my files**.
2. Better, if Windows boots: an **in-place repair install** from the ISO, which keeps applications too. Both are covered in [reinstall Windows without losing data](https://www.mytechnician.tech/tips/reinstall-windows-without-losing-data/).

## Before the Next Patch Tuesday
* Back up, or at minimum copy irreplaceable files to another drive: [back up your PC](https://www.mytechnician.tech/tips/backup-pc-windows-backup-file-history/).
* Turn on System Protection and create a restore point.
* Note your current build with `winver`.
* Set **Active hours** so updates never restart the machine mid-task.

## One Honest Caveat
Cumulative updates close security holes that are already being exploited. Rolling one back leaves those holes open on your machine. Treat a rollback as temporary: wait a week, then install the next cumulative release or the reissued KB once Microsoft has corrected it.
