Standard user account will not accept Admin password

[ronnox]

In Windows Vista, when I try to execute a program from a standard user account that requires the admin password, it says the password is incorrect. It is the correct password because using the same password, I can log in to the Admin account.

Can someone help?

Welcome
Lets first make sure that the problem is not worse than it seems
Run an sfc check

Make a full anti virus scan
Download and run a full scan with malwarebytes.
If all are negative
Open another user account and see if the problem persisits, it may be corruption in one account.

Hello Ronnox, and welcome to Vista Forums.

As a test while logged in the administrator account, change your password. Afterwards, see if it will allow you to enter the new password while in the standard account.

Hope this helps,
Shawn

Tried that but it still would not work.

Hello ronnox and welcome to the forums

Can you do the following for me please?

CKScanner

Please download CKScanner from here to your Desktop.

Make sure that CKScanner.exe is on the your Desktop before running the application!

Double-click on CKScanner.exe and click Search For Files.
After a very short time, when the cursor hourglass disappears, click Save List To File.
A message box will verify the file saved
Attach the log CKFiles.txt that has been created on your desktop with your next post

Malwarebytes Anti-Malware (As Rich instructed)

Download and install MBAM from here
Run a full scan and attach the log with your next post for me to analyse

OTL

Download OTL to your desktop.
Double click on the icon to run it. Make sure all other windows are closed to let it run uninterrupted.
When the window appears, underneath Output at the top change it to Minimal Output.
Under the Standard Registry box change it to All.
Check the boxes beside LOP Check and Purity Check.
Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.


Once OTL has completed its first scan it will save notepad copies of the scans in the folder that OTL was started from. Unless set to produce an Extras log it will only produce OTL.txt in subsequent scans.

A copy of an OTL fix log is saved in a text file at

:\_OTL\MovedFiles
in most cases this will be C:\_OTL\MovedFiles
