<p>If you have issues with your XP system that automatically logs you off upon a successfull logon which can be caused by Spyware (in most cases). One of those spyware applications is &#8216;Search Assistant&#8217; which is usually located in the &#8216;<span style="color: #003366;">C:\Program Files\WindowsSA</span>&#8216;</p>
<p>It can also contain &#8216;<strong>omni*.*</strong>&#8216; files in the Windows\System32\ directory that are linked to &#8216;<strong>Userinit</strong>&#8216; key. If you delete these files using your anti-virus or anti-spyware application, you are not able to login.</p>
<p>To be able to use the registry on the machine where you&#8217;re unable to login, you have two options:</p>
<p>&#8211; Use the recovery console<br />
&#8211; Use another machine on your network and run the registry editor. Select <strong>&#8216;File&#8211;>;Connect Remote Registry&#8217;</strong>. In the prompt box, enter the computer name of your PC.<!--more--></p>
<p>Ok, here&#8217;s what to do when you access the registry:</p>
<p>1. Navigate to<br />
&#8220;<span style="color: #003366;">HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon</span>&#8221;</p>
<p>2. If there is a key named &#8220;<strong>OldUserinit</strong>&#8220;, delete the &#8220;<strong>Userinit</strong>&#8221; key and rename the &#8220;<strong>OldUserinit</strong>&#8221; key to &#8220;Userinit&#8221;.</p>
<p>3. The &#8220;<strong>Userinit</strong>&#8221; key should now say<br />
&#8220;<span style="color: #003366;">WINDOWS_PATH\system32\userinit.exe</span>,&#8221;</p>
<p>&#8220;<strong>WINDOWS_PATH</strong>&#8221; is a variable to where you have your windows installed.<br />
It usually is like this &#8220;<span style="color: #003366;">C:\WINDOWS\system32\userinit.exe,</span>&#8221;</p>
<p>After this Windows logon should work normally and you should be able to run a full system scan with your anti-virus application.</p>
