Dell XPS 15 9550 (Intel i7, 16GB Ram, 500GB SSD) was behaving badly and slow, so I decided a Windows reset was worth a shot.
Now I cannot login... The start screen comes up with Administrator "your account has been disabled. Please see your system administrator". It originally came up with Other User login but wouldn't accept Microsoft account details, so I attempted to boot in Safe Mode to change users, only to get a sihost.exe message.
And now it's stuck in the start screen with Administrator apparently disabled. How do I get out of this and why would it not start from scratch? (Ie. Create new user)
TIA for any help,
(P.s. please keep things simple... I'm not an advanced user)
Volunteer Moderator NOTE: This normally means the install was too corrupted to Reset or is seriously infected. You will be better off and save time wiping the hard drive clean while doing a gold standard Clean Install Windows 10 following the illustrated steps in this link which compile the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy.
Since this is also sometimes due to infection, make sure during the booted install to follow the illustrated steps to delete all partitions down to Unallocated Space to get it cleanest, then click Next to let it auto-create the needed partitions, format them and begin install - this makes it foolproof.
