How To Identify Programs That Slows Down Your Computer During Startup

Frustrated that your Windows PC is slow when booting, or logon takes forever to complete? Wish you could stop programs from auto starting or worried you may have spyware?

For many Windows users this is a common occurrence that seem impossible to fix unless your a seasoned System Administrator.

Many tools exist that will help dig inside your Computer but end up being incomplete with identifying all possible locations where programs can hide.

Fortunately a tool called Autoruns does exist and is capable of hunting down every program that autostarts during boot or when you logon.

Autoruns is a powerful Windows utility that shows you what programs are configured to run (auto start) during system bootup or login. Included locations are programs in your Startup folder, Run, RunOnce, and other Registry keys, browser add-ons and File Explorer add-ons.

Autoruns works on all versions of Windows including Windows XP, Server 2003 64-bit Edition (for x64) and can be downloaded from Microsoft Technet site (formally Sysinternals).

Once downloaded, unzip the contents into a folder and run autoruns.exe. The first tab Autoruns displays is everything that autostarts on your Computer.

 

Autoruns includes 15 tabs that you can select to display areas such as Internet Explorer, Services, and Logons where programs can auto start.

 

Autoruns Modes

Three modes exist for displaying programs that can be set in the Options menu:

Include Empty Locations - will display locations of known location that programs can autostart. By default this setting is uncheck.

Verify Code Signatures - will display on Systems that support image signing verification (icon next to program name). "Not Verified" will display if an image does not exist.

Hide Microsoft Entries - omits images that have been signed by Microsoft.

After selecting a mode, you will need to refresh the list from the menu under File.

Autoruns Features

Autoruns has an interaction feature by right clicking on a program. You can Search Online for programs that you do not recognize, or Jump To the location of the program such as the Registry or Startup folder, or display Properties of the selected item.

If you also have Process Explorer running, Autoruns will switch to Process Explorer to show process information for the program that was selected.

One feature that make Autoruns standout from other utilities is the ability to take save a snapshot of all entries, then compare the entries after installing applications or making configuration changes. When comparing changes, items diplayed in "green" represent new items. To save, select Save from the File menu.

Word Of Caution

When troubleshooting your Computer for slow startups or logon problems, it is best to isolate one program at a time by deselecting the program. Make sure you document all changes in the exact order you made before testing and BACKUP all personal data. Although you can delete programs, it is recommended not to delete unless you are a Computer Professional.
