Issue: How to fix "This user wasn’t added to this PC" 0x800b0109 error in Windows?
Hello. When I try to add a new account on my Windows PC, I get the “This user wasn’t added to this PC” message with a 0x800b0109 error code. Is it possible to fix this issue?
Solved Answer
When trying to add a new user account on their Windows 11 or Windows 10 PC, users frequently run into the error message “This user wasn't added to this PC” with the error code 0x800b0109. Due to the fact that it stops users from adding or establishing new user accounts on their computers, this issue can be irritating and perplexing. This problem is especially troublesome because it may prevent users from creating extra accounts for friends, family members, or other uses.
The error message indicates an issue with the user account creation procedure, which is frequently brought on by underlying system or configuration problems. Regardless of whether they are using Windows 11 or Windows 10, users may get this issue while attempting to add a new local or Microsoft account.
Users may be impacted by this problem if it restricts their ability to manage and personalize user accounts on their PCs. Where several users require separate accounts in order to access the system with their settings and preferences, such as in shared or familial settings, this could be extremely problematic. Additionally, if users run across this problem when attempting to establish a new account, they can run into difficulties if they need different accounts for work and personal use.
Checking for Windows updates, making sure user account control settings are set up properly, and testing network connectivity are all potential fixes for this problem. Users might also need to investigate any potential registry or system file corruption.
