This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I had issue with my Anti-Virus agent uninstalling. The AV vendor required I drop to safe mode to run their utility. Once I got to safe mode (MSConfig) I found that I had no available account with administrative privileges, so I can't do anything worth doing.
I checked my Users and Groups and my standard local and domain admin accounts are there. Unfortunately I can't use my domain accounts because I neglected to check 'networking' in the safe mode configuration in MSConfig and my local admin account apparently is not seen on this system as it is on 60+ others.
I tried troubleshooting > advanced options but without administrative privileges I can't do anything, not even reset the system to rebuild it.
Might also try from a clean boot.

Are you saying you have no problem with your local admin account when you startup normally? A clean boot has no effect on this this.

I can login with what is/was the local admin account used to setup every system, even in safe mode with networking unavailable. The trouble is logged in with what I know is the local administrative account the system isn't allowing me to do anything essentially tell me I have no administrative access.
No the clean boot hasn't helped. By my own hand, using msconfig, I chose safe mode and neglected to check to use networking. So I'm stuck in a cycle of booting to safe mode and no way to change it back OR even to reset the system (I'd be done by now if I could just reset windows and build it over again)
No the clean boot hasn't helped
Yea the clean boot was to work around the other issue. If the local admin account is now somehow corrupt / unusable you might need to try a system restore.

If you are in a basic account and need admin then you can make use of the Built-in Admin account.
