How to Fix Search Companion in Windows

1. Login as Administrator to Windows. You can also login with any username that has computer admin privileges.
2. Click 'Start' and then 'Run.' Execute these strings in the 'Run' box: 'regsvr32 /i %windir%\srchasst\srchui.dll' (without the parentheses) and then 'regsvr32 %windir%\system32\jscript.dll' again without parentheses. You should see the message 'DllRegisterServer in <filename.dll> succeeded for each DLL registered, so two in total.
3. Log off and then log back on, and check the Search Companion window to ensure that it is now working correctly and isn't displaying blank. If it's still blank, you'll need to repair the search components using a specific Windows INF file.
4. Click 'Start' then 'Run.' Type '%systemroot%\inf' and then click 'OK.' Don't include the parentheses in the string. Now a window will open. In the window, locate the file named 'srchasst.inf,' right-click it, and choose 'Install.' You'll now be prompted to insert the Windows XP CD, so do so and point to the i386 folder on the CD. If you installed Windows XP Service Pack 1,2, or 3 separately after installing Windows XP, point to '%windir%\ServicePackFiles\i386' instead. Search Companion is now reinstalled and should operate correctly.
