Window password at log on

[Michael]

Like an idiot I changed my password in the dark. Of
course now I'm not sure what it is.I am the administator
for this,home computor shared with my two sons.I can
still get to everything by logging in under their names-
shared folders to my documents. Using Windows XP, can I
solve my problem without uninstalling and reinstalling
Windows?

The password is Case Sensitive.
Check Caps Lock and try various of Capital combinations.

Or
Log in to any account with Administrator access.Go to User Accounts in
Control Panel.
Select yourself.
Then Change Password.
Or
Reboot to Safe Mode, select Administrator, leave password blank.
Then go to User Accounts in Control Panel.
Select the user and change the password.
If you are using Windows XP Pro and have encrypted data, you may
permanently lose access to the encrypted data.

Another option is to install Windows XP on another partition and take
Ownership of your data.
You could also perform another installation on the same partition,
although this is not a permanent fix and it is recommended to perform
a Clean Installation after retrieving your data.

After this is resolved, take precautions to not lose the password.
