How to Fix Windows 11 Not Working After Update

If your computer is too unstable, sluggish, or constantly crashing to navigate the normal desktop environment, booting into Safe Mode is your best starting point. Safe Mode loads Windows 11 with a minimal set of drivers and background services, preventing third-party software and conflicting updates from interfering with your troubleshooting steps.

To access Safe Mode when your system can still boot to the sign-in screen, hold down the Shift key while clicking the Power icon in the bottom right corner, then select Restart. Once your PC reboots into the recovery environment, navigate to Troubleshoot > Advanced options > Startup Settings and click Restart. After your computer restarts again, press 4 or F4 to enable Safe Mode. If your PC cannot reach the sign-in screen at all, hard-reset your computer three times consecutively during the startup logo to automatically trigger the Windows Recovery Environment, and follow the same path.

If you notice performance issues immediately after a specific security patch or feature update installation, rolling back that update is the fastest way to stabilize your system. Microsoft occasionally releases patches that conflict with certain hardware configurations, and removing the latest package provides immediate relief while waiting for a hotfix.

To uninstall an update from within the desktop or Safe Mode, open your settings using Windows Key + I and go to Windows Update > Update history. Scroll down to the Related settings section and click on Uninstall updates. Locate the most recent update that caused the malfunction, click the Uninstall button next to it, and confirm your choice. Your computer will require a restart to complete the rollback process, after which your system performance should return to its prior state.

Corrupted or missing system files are a frequent byproduct of interrupted or flawed update installations, which can break core Windows 11 features and user interfaces. You can easily diagnose and automatically repair these underlying operating system file corruptions using the built-in Deployment Image Servicing and Management and System File Checker command-line tools.

Right-click the Start button and select Terminal (Admin) or Command Prompt (Admin). First, type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter to repair the Windows system image. Once that scan finishes successfully, type sfc /scannow and press Enter to scan and replace damaged system files. Allow both processes to complete fully without closing the window, then restart your computer to apply the repairs.

Outdated or incompatible display, network, and chipset drivers are major culprits behind system crashes, black screens, and hardware malfunctions following a major operating system update. When Windows updates overwrite existing hardware drivers with generic versions, conflicts often arise that disrupt normal device operations.

Right-click the Start button and choose Device Manager. Expand the category containing your problem device, such as Display adapters or Network adapters, right-click your hardware component, and select Properties. Go to the Driver tab and check if the Roll Back Driver button is clickable. If it is, click it to revert to the stable driver version installed prior to the update. If rolling back is not available, select Update driver and choose to search automatically for updated drivers, or visit your hardware manufacturer official website to download the latest certified package.

If standard repair commands and update rollbacks fail to resolve the instability, your operating system installation may have sustained deep registry or component damage. Resetting Windows 11 reinstalls core operating system files while giving you the option to keep all of your personal documents, photos, and downloaded applications safely intact.

Open your settings via Windows Key + I and navigate to System > Recovery. Under the Recovery options section, click the Reset PC button next to Reset this PC. Choose the option labeled Keep my files, select either Cloud download or Local reinstall, and proceed through the on-screen prompts to initiate the reset. This procedure refreshes your entire operating system environment and cleans out corrupted update remnants without deleting your personal user files.
