Uninstall and Block a Faulty Windows Update: The Complete Guide
A Windows update installs, your PC restarts… and then everything goes wrong: a blue screen (BSOD), a printer that no longer responds, flaky Wi-Fi, apps that crash, or performance falling off a cliff. It’s frustrating, but reversible. This guide shows you how to cleanly uninstall a faulty Windows update — whether your PC still boots or not — then prevent its automatic reinstallation, on Windows 11 and Windows 10, Home edition and Pro alike.
Who this guide is for: any user whose computer became unstable right after an update (security patch, feature update or driver), and who wants to roll it back and then lock the situation down.
Prerequisites: an administrator account, about 15 minutes, and — strongly recommended — a recent backup of your data. No advanced skills are needed for the first steps.
Step 1: back up before you touch anything
Uninstalling an update is rarely dangerous, but any system operation carries some risk (especially via the command line or on an already-unstable PC). Five minutes of backup beats an evening of recovery.
Copy at least your Documents, Pictures, Desktop and Downloads folders to an external drive. A portable SSD is ideal: fast, sturdy, and reusable as a rescue disk.
- The Samsung T7 (1 TB) delivers speeds up to 1050 MB/s and survives drops — perfect for an express backup before you dig in. Check the Samsung T7 1TB SSD price on Amazon

Tip: before a big update in the future, also create a system restore point (Start menu → “Create a restore point”). It lets you roll back to an earlier state in a few clicks.
Step 2: identify the update responsible
Not all updates uninstall the same way. First you need to know what type the problematic one is. Open Settings → Windows Update → Update history. You’ll see three main families:
- Quality updates: the monthly cumulative patches (Patch Tuesday), identified by a KB number (e.g. “KB5094126”). These are the most frequent and the easiest to remove.
- Feature updates: the large annual versions (23H2, 24H2, 25H2…). They uninstall differently, via a “roll back.”
- Driver updates: hardware (graphics card, Wi-Fi, printer…). These are handled in Device Manager.
Good to know: note the exact KB number or name of the suspect update. A quick web cross-check (the KB plus “issues” or “problem”) often confirms a bug is already reported — and that you’re not alone.
Step 3: uninstall a quality update (monthly patch)
This is the most common case. The graphical method is enough 9 times out of 10.
- Open Settings → Windows Update → Update history.
- Scroll to the bottom and click Uninstall updates.
- Find the faulty KB in the list, click Uninstall, then confirm.
- Restart the PC.
Warning: some boot-related security updates (Secure Boot, TPM) show a grayed-out or missing option. In that case, use an admin command prompt:
wusa /uninstall /kb:5094126
Replace the number with your KB. If Windows refuses (“the update is required”), you’ll need the recovery environment (Step 6) or you’ll have to wait for the official fix.
Step 4: undo a feature update (roll back to the previous version)
If the problem appeared after a major version (say the jump to 24H2 or 25H2), Windows keeps the ability to roll back for 10 days without losing your files.
Go to Settings → System → Recovery, then click Go back (“Go back to the previous version of Windows”). Follow the wizard: it reinstalls the older version while keeping your documents and most of your apps.
Good to know: after 10 days, the Windows.old folder is automatically deleted and the button disappears. If a major update just arrived and you’re hesitating, do not free up disk space with Disk Cleanup: that would erase your safety net.
Step 5: roll back a faulty driver
Black screen, stutter, silent printer, no sound? The culprit is often a driver pushed by Windows Update. Good news: Windows keeps the old one.
- Right-click the Start menu → Device Manager.
- Expand the relevant category (Display adapters, Network adapters, Printers…).
- Double-click the device → Driver tab → Roll Back Driver.
- State the reason and confirm, then restart.
Tip: if “Roll Back Driver” is grayed out, uninstall the driver (ticking “Delete the driver software”) then reinstall the older version from the manufacturer’s official site. Then block its automatic reinstallation (Step 10).
Step 6: uninstall an update when Windows won’t boot
If the update prevents booting entirely (loop, blue screen at boot), you’ll need WinRE (the recovery environment).
Power on the PC and, as soon as the logo appears, force a shutdown with the power button. Repeat two or three times: Windows switches to “Automatic Repair.” Then go to Troubleshoot → Advanced options → Uninstall Updates, and choose:
- Uninstall latest quality update (for a monthly patch), or
- Uninstall latest feature update (for a major version).
For stubborn cases, the WinRE Command Prompt allows a surgical removal:
dism /image:C:\ /get-packages
dism /image:C:\ /remove-package /packagename:<KB_package_name>
Adapt the C:\ letter to your Windows volume (find it with diskpart then list volume).
Warning: if your drive is BitLocker-encrypted, WinRE will ask for the recovery key. Keep it handy — we cover where to find it in our dedicated BitLocker guide.
Step 7: pause updates (the immediate stopgap)
Once the update is removed, Windows will want to reinstall it. The simplest move to catch your breath: pause updates.
In Settings → Windows Update, use Pause updates. You can push the deadline in blocks (up to 35 days), and extend before the deadline to buy more time.
Good to know: the July 2026 security update gradually introduces a near-unlimited pause (with a specific date picker). If the option is available to you, it offers far more comfortable breathing room — until a reliable fix lands.
Step 8: block a specific update with “wushowhide”
Pausing blocks everything; sometimes you only want to stop one update from coming back while still receiving the others. That’s the job of the “Show or hide updates” tool (the wushowhide.diagcab file).
Download it from a trusted source, run it, choose Hide updates, tick the KB to ban, then confirm. Windows will stop offering it.
Warning: this tool is old and Microsoft no longer actively maintains it; it may not work on the very latest Windows 11 builds. If so, switch to the Group Policy (Step 9) or registry (Step 10) methods, which are more robust.
Step 9: block and defer via Group Policy (Pro and Enterprise editions)
On Windows 11/10 Pro, Enterprise and Education, the Group Policy editor offers fine-grained control. Open it with gpedit.msc, then go to:
Computer Configuration → Administrative Templates → Windows Components → Windows Update → Manage updates offered from Windows Update.
You can notably:
- Defer quality updates by several days (to let bugs surface).
- Defer feature updates and choose the target version to keep (for example staying on 24H2).
- Pause a category of updates temporarily.
Tip: enable “Select the target Feature Update version” and specify the version you want to keep. Windows will no longer offer higher versions while this setting is active.
Step 10: block via the registry (Home edition)
The Home edition has no gpedit, but the registry allows the same locks. Open regedit (right-click → Run as administrator) and go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Create the WindowsUpdate key if it doesn’t exist, then these DWORD (32-bit) values:
TargetReleaseVersion=1TargetReleaseVersionInfo(a string value) = the version to keep, for example24H2.
Windows will stay locked on that version and stop offering a higher jump.
For drivers, add the DWORD ExcludeWUDriversInQualityUpdate = 1 in the same key: Windows Update will stop forcing hardware drivers, which you’ll then manage manually.
Good to know: setting your Wi-Fi connection as “metered” (Settings → Network → Properties → Metered connection) is a simple, risk-free brake: Windows downloads far fewer updates automatically there. Handy as a temporary fix.
Warning: an incorrect registry change can destabilize the system. Export the key (right-click → Export) before any change, so you can restore it.
What to do next: don’t stay blocked forever
Blocking an update is a temporary measure, not a permanent policy: security patches protect your PC. As soon as Microsoft releases a fix for the fix (often within a few days to two weeks), lift the block and let the new version install.

Frequently asked questions
Does uninstalling an update delete my files? No. Removing a patch or rolling back to the previous version keeps your documents and applications.
The KB keeps coming back despite uninstalling: is that normal? Yes, as long as you haven’t blocked it (Steps 7 to 10). Uninstalling isn’t enough; you also have to prevent reinstallation.
I’m in a company: which method should I favor? Group Policy (or Intune / WSUS) for centralized control, rather than per-machine tweaks.
Can I disable Windows Update completely? It’s possible (the wuauserv service), but strongly discouraged: you’d cut yourself off from security patches. Prefer a targeted pause.
In summary
Faced with a faulty Windows update, the path is clear: identify its type (Step 2), uninstall it with the right method — Settings, roll back, driver or WinRE (Steps 3 to 6) — then block its reinstallation via pause, wushowhide, Group Policy or the registry (Steps 7 to 10). And above all, lift the block as soon as a reliable fix is available: security first.
