If you have a folder named defaultuser100000, here’s what it actually means and whether you can delete it or not.
Recently, out of nowhere, I’ve started seeing two new folders with the “defaultuser100000″ and ” defaultuser100000.ComputerName” name. I don’t know what created the folders or why they are created. In my case, the folder is located within the “Users” directory in the root of the C drive. Additionally, the folder is completely empty. i.e, it contained no folders or files.
So, I did some digging but could found very little information about the folder.
What is defaultuser100000 Folder?
Like I said before, there is very little information about this folder. Most likely, this is a new occurrence in windows 10 and the system might be automatically creating this folder while installing new windows 10 Updates.
Since the folder name contained “defaultuser”, at first, I thought this folder is related to the Default User account in windows. However, that’s not the case because the Default User user account is disabled by default. If you want to, you can verify the current status of the Default User.
To do that, simply open the start menu, type “lusrmgr.msc” and click on the result. This action will open the Advanced User Account Manager. Here, double-click on the “Users” folder. In the list of users, you should see the “Default User”. If the user account icon contains a little down arrow, it means that the user account is disabled.
Since the Default User account is disabled, the folder doesn’t belong to that user.
Simply put, the best guess is that Windows 10 is automatically creating this folder for installing, uninstalling, or managing the updates. Once it is done, it is simply abandoning the folder.
Can I Delete defaultuser100000 Folder?
You should not delete the folder if the Default User account is enabled in your system. If you really want to, disable the Default User account first and then proceed.
Since the folder has little to no value, you can safely delete defaultuser100000 folder as long as the Default User account is disabled. Keep in mind that you need to have admin privileges to delete it.
However, before proceeding to delete the folder, I strongly recommend you create a full backup of windows 10. That way, even if something unexpected happens, you can restore your system and get back to work.
That is all.
