I recently bought Lenovo T61 with Windows XP service pack 2. Before telling the problem I wuld like to tell the actions I did on my laptop.
Somehow I could not see the welcome screen may be due to some changes in the User settings. I read the articles and got misguded/misunderstood.
I went to the regedit and changed the Logon Type value from 1 to 0 in the below path
From there onwards I could not edit any value in the regedit. I am getting the below message
" Cannot edit LogonType:Error writing the value's new content".
Even I could not change the system date and time, any installation givign an message saying login as Administration or only administration can perform the activity.
I have a back up with the correct settings of regedit, but I could not as I lost the Administration priviliges.
Please let me know if there is nay way to get back the admimnistration privliges
Thanks and Regards,
