Computers often speak in riddles, telling you there is a problem but not spilling the beans on what is causing it. On that note, start with a classic but often underestimated step — restarting your computer. This action might sound simple, but it can work wonders. A restart refreshes system processes, potentially clearing any glitches causing the sign in error.

Save any open documents or files you are working on to prevent data loss. 2\. Click on the **Start** menu → power button icon → **Restart** to restart your computer. ![User Profile Service Failed the Sign In - Restarting the computer](https://adamtheautomator.com/wp-content/uploads/2023/10/image-16.png) Restarting the computer 3\. Once your computer boots up, try logging in with your user account and see if the sign-in error has been fixed. If not, no worries. A computer restart is a foundational troubleshooting step that sets the stage for more advanced fixes, as in the following sections. ## **Booting Into Safe Mode** If the error persists after giving your system a fresh start, you may need to wear your detective glasses to spot the culprit. Dig deeper to isolate and fix various system issues, starting with booting into Safe Mode to start your computer with only essential system services and drivers. To boot into Safe Mode, follow these steps: 1\. Press the Window + R keys to open the **Run** dialogue box. 2\. Next, type **msconfig** and press Enter to launch the System Configuration window. ![Launching the System Configuration window](https://adamtheautomator.com/wp-content/uploads/2023/10/image-19.png) Launching the System Configuration window 3\. In the System Configuration window, choose your target OS from the list (i.e., **Windows 10**), and configure the following **Boot options**: * **Safe boot** – Tick this box to set your system to boot into Safe Mode after a reboot. * **Minimal** – Choose this option so that only essential system services and drivers start on reboot. Once configured, click **Apply** and **OK** to save the changes. ![Configuring the system boot options](https://adamtheautomator.com/wp-content/uploads/2023/10/image-18.png) Configuring the system boot options 4\. Lastly, click **Restart** when prompted to confirm restarting your computer. If you can log in to your user account in Safe Mode, there is one less problem to work on. Yet, the failed sign-in error might be caused by corrupted system files, so jump to the following sections to keep looking for the best solution. ![Confirming the computer reboot](https://adamtheautomator.com/wp-content/uploads/2023/10/image-17.png) Confirming the computer reboot ## Scanning and Repairing System Files If safely booting up does not bring up the failed sign-in error, but the normal boot still does, you may need a bit of digital-first aid. The System File Checker (SFC) utility allows you to scan and repair system files for corruption or errors. To scan and repair your system files via SFC, carry out the steps below: 1\. Boot into Safe Mode, and [open Command Prompt as administrator](https://www.howtogeek.com/194041/how-to-open-the-command-prompt-as-administrator-in-windows-10/). ![Opening the Command Prompt with administrative privileges](https://adamtheautomator.com/wp-content/uploads/2023/10/image-21.png) Opening the Command Prompt with administrative privileges 2\. Next, run the below [`sfc`](https://support.microsoft.com/en-au/topic/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system-files-79aa86cb-ca52-166a-92a3-966e85d4094e) command in the Command Prompt to scan (`/scannow`) your system files for any issues and attempt to repair them if necessary. Patiently wait for the process to complete, as it may take some time, and avoid interruptions. ```bash sfc /scannow ``` ![Scanning and repairing system files via SFC](https://adamtheautomator.com/wp-content/uploads/2023/10/image-20.png) Scanning and repairing system files via SFC 3\. Once the scan and repair process completes, restart your computer and check if the “User Profile Service failed the sign in” error is resolved. > _💡 Besides fixing corrupted system files, sign-in errors may also be caused by third-party applications. Therefore, uninstalling recently installed applications via trusted software like Revo Uninstaller may also help fix the sign-in issues._ Related:[Optimize Windows System Performance Using Revo Uninstaller](https://adamtheautomator.com/revo-uninstaller/) ## **Restoring Your System to a Previous State** Imagine you have already given your system a fix for corrupted system files but still getting a failed sign-in error — frustrating, right? Why not dip into a bit of time-travel magic? Restoring your system to a previous state is like hitting the rewind button on your computer, returning it to a time when everything ran smoothly. This process lets you undo recent changes that triggered the sign-in issue. To perform a system restore, proceed with the following steps: 1\. Open the Run dialogue box (Win+R), input **rstrui,** and press Enter to open the System Restore window (step two). ![Opening the System Restore window](https://adamtheautomator.com/wp-content/uploads/2023/10/image-25.png) Opening the System Restore window 2\.
