Handling Windows updates is always going to be an adventure a couple of people go through without having to go through several issues and errors.

Database Error during Windows Update
The error message stating “Potential Windows update database error detected” can appear during several different processes regarding Windows update. First of all, it can appear while simply updating Windows to a newer version. Apart from that, it can occur when you select several other functions such as “Repair Windows Update” or similar. You may encounter several different codes or no code at all but the solution to each of them is the same.
This may look quite frustrating to people who struggle to go through with the update after several months of delaying only to be faced with an error message saying something went wrong. There are several solutions to the issue and you may have to try all of them to end up happy with the end product.
Repair Corrupt System Files
Download and run Restoro to scan for corrupt files from here, if files are found to be corrupt and missing repair them and then check if it still gets stuck, if it is then try the Solutions listed below.
Solution 1: Use the SFC Scan
The solution to this problem suggested by Microsoft helped an unusual amount of people, unlike their other solutions which looks almost automated. Try this out before doing anything else. The SFC stands for System File checker and it checks your computer for faulty or corrupt system files and it automatically repairs them.
- Enter “Command Prompt” in your Search box, right click on the icon and select “Run as administrator.
- Type “sfc/scannow” and press Enter.
- The process should begin and automatically fix faulty files.
Running SFCSolution 2: Use the DISM Tool
DISM stands for Deployment Image Servicing and Management and it’s a tool which can be used to repair and service Windows images. This is also recommended by Microsoft as it can automatically fix certain issues.
- Run the Command Prompt as Administrator as described in Solution 1.
- There are two separate commands you need to use in order to complete the process:
DISM.exe /Online /Cleanup-image /scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
- You will have to wait for a certain amount of time for the process to finish but DON’T cancel it yourself in any way.
Solution 3: Resetting the Windows Update Components Manually
This process is somewhat more advanced and it means that you will manually reset the entire update utility and start the updating process from scratch. Follow the instructions below very carefully.

- You can use the following commands in order to stop the processes Windows Update Services, MSI Installer, BITS, and Cryptographic.
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
- You need to rename two folders, SoftwareDistribution and Catroot2. You can try to find them yourself but it’s definitely easier just to copy the commands below. You can see the location of these files in the command if you want to rename them manually.
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
- It’s time to start the processes we ended in the Step 2 by using the following commands:
