I have a Dell laptop now that's totally locked in a lsass exe loop.. An so far the only way I see it can be fixed is to have the disk or buy one to recover your pc. I THINK THIS IS ALL DONE BY WINDOWS TO GET PEOPLE TO SPEND $ ON RECOVERY DISKS AN PRODUCT KEYS. It's all a scam.
not true ,you do not have to buy any disk ,you should have created recovery disk when you bought the lDell new ,and if you didn'y contact Dell and they will send you disk ,charging a small fee maybe ,has nothing to do with Windows[Microsft ]
