Startup and Visibility:

• Hide Status Window  –  (Premium Edition only.)  Removes the status window so the maintenance runs completely silent/invisible to the user operating the PC.
• Show Cancel Prompt  –  Offer a cancel prompt before starting a maintenance routine.  This option will always override the silent operation offered by the previous setting.

Maintenance Tasks:

• Clear Print Queue  –  This will forcefully remove any stuck jobs in the print queue if they exist.
• Delete Temp Files  –  This deletes all Windows temp files, Windows update related temp files, and all temp files from each individual user account on the PC.
• Delete Temp Internet Files  –  This deletes all temporary internet files from the Internet Explorer, Firefox, Chrome, Chrome Canary 64bit, Chromium, and Comodo Dragon web browsers, for each browser profile in each user account on the PC.  This option will close any open web browsers.
• Delete Internet History  –  Deletes all internet browsing history from the Internet Explorer, Firefox, Chrome, Chrome Canary 64bit, Chromium, and Comodo Dragon web browsers, for each browser profile in each user account on the PC.
• Delete Cookies  –  Deletes all cookies from the Internet Explorer, Firefox, Chrome, Chrome Canary 64bit, Chromium, and Comodo Dragon web browsers, for each browser profile in each user account on the PC.
• CleanMgr.exe  –  Automates CleanMgr.exe, an internal Windows utility for user run maintenance.  CleanMgr will be run with the options selected to cleanup everything except MS Office setup files (which can be needed by office,) Compress Old Files (with today’s hard drive space you should never do this!!), Empty Recycle Bin (because you may have something important in there), and cleanup memory dumps (which can be useful for repair technicians to troubleshoot PC issues.)
• Delete %windir%$NTUninst dirs  –  This option removes Windows update and service pack backup directories to free up lots of hard drive space, however after this is performed Windows updates will not UNinstall successfully if you should ever need to uninstall a Windows update.
• ProcessIdleTasks  –  This is a Windows internal API called to perform a lot of under the hood maintenance in Windows, including defrag/prefetch organization and other misc optimization tasks.  This option can take a LONG time, 2-20 minutes even, depending on how much maintenance needs to be done, or the last time this API function was run.  This API function actually runs automatically in Windows every 3 days, however it will only run when the computer is IDLE (meaning you aren’t using it for anything else) and these days that only occurs if you leave your PC on all the time.  If so, this option is redundant, if not, such as the case of a laptop, then you will want to ensure this option runs.

Internet / Networking Related:

• Set Homepage  –  If you place a URL in this field, it will reset the homepage of Internet Explorer, Firefox, Chrome, Chrome Canary 64bit, Chromium, and Comodo Dragon web browsers to that URL.
• Clear Proxy Settings  –  If you aren’t on a corporate network, you aren’t running specialized proxy software on your PC/network, or you don’t know what this is, then you don’t have the need for them and these settings should never exist.  Frequently these settings are used by malicious software to force your internet browser to display malicious content before you actually reach your intended destination.
• Disable IE Work Offline mode  –  Disables the “Work Offline” mode in Internet Explorer, which will switch off internet browsing in that browser.  This setting is sometimes accidentally enabled via shortcut or menu by users and often they don’t know how to restore internet within IE.  This option will close any open web browsers.
• Reset HOSTS file to default  –  Sometimes used to block ad content by specialized software you may have installed, this can also be used by malicious software to redirect you to a malicious web payload instead of your intended destination.

Finish Actions:

• Scan with MSSE / Windows Defender  –  This option scans with Microsoft Security Essentials (if installed, Windows XP – Windows 7) or if not installed, it utilizes Windows Defender (built-in on Windows Vista – 8.x)  This function will fail if Defender has been disabled.
• Email on Completion  –  (Premium Edition only.)  This option utilizes the email settings you have configured on the SMTP Configuration page to send you an email of the maintenance report when a maintenance routine completes.
• Create Restore Point  –  This option creates a Windows System Restore point after the maintenance routine, so you can restore your computer to this point in time should this become necessary in the future.  You must name the restore point in the box below.
• Force a reboot of the PC  –  This restarts the computer after maintenance has completed.  A good practice, but not necessary.  Options under this allow you to optionally shutdown the PC entirely, and to offer a cancel prompt first in case you may be at the PC and need to cancel the reboot/shutdown operation.
