NotepadCheck Dist Utility & Defrag

Check Disk Utility & Defragment

Check Disk Utility & Defragment

This lesson covers the Check Disk Utility and Defragment functions.  We examine what these processes do, how they differ and are similar, why they are an essential part of good system maintenance and what exactly happens that makes them effective.

For example, what happens to files and folders located on the drive when you perform a check disk scan vs. scan & fix and what triggers the need to perform this system check?

You’ll also learn what happens the hard disk drive during the defrag process by diagramming and examining the hard drive components


NotepadManage Windows Update options

Critical updates and security updates are the most critical.  Windows updates

XP no longer is being updates.  Update your system to at least vista or windows 7 asap.

Windows updates provide Bug fixes

Set update config- Download/Install Automatically

Download but ask to install.

Ask download/install

Set time to install

May require restart.

Windows will check for updates and let you know when to install

Never Check for updates



NotepadPatch Management

Patch management is the process of applying updates, bug fixes security patches  service packs and new drives and new software to our system after testing thoroughly  don’t just take a patch and install as unexpected consequences may happen.  Make sure the update is tested thoroughly.

Patch management cycle:

Keep inventory of all the that need to be updated

Determine patch cycle – each program or vendor have different cycles.  Keep record so we keep updated.

Check once per vendor’s update cycle at the beginning of the update cycle.  Research patch risk vs the benefit…may not want to deploy.

Patch deployment process. Engineers testing (core group)test and repeat as necessary. Don’t deploy before thoroughly tested.

Deploy patches and verify deployment. Not just enough to put the patches out there but test and make sure computers that are not fully patched are not on the network.  Don’t need to make a mistake and plug as many holes as we can.  Critical updates must be pushed our as soon as possible.  Knowing how to wave some patches is important.


Research the patch and verify deployment


NotepadPreventive Maintenance

Tools –

Critical tool is backup

XP has  NT backup/files/folders

Vista – Back/Restore center (files and folders)

Windows 7 – Backup and Restore files and folders and computer image.

System restore tool allow us to create restore points. Allows to  go back in time to a previous setup.  It does not delete restore or change any of our folders or files where we actually save documents, files pdf.  Wont delete them.  Can be good and bad.  We created a restore point .  System restore can not be an antivirus.  System restore will not  remove the virus system restore will not delete the virus. It will still be there in that file or folder.  If we downloaded from intranet as it will still be in that file or folder.


Chkdsk is a command\program that scans the hard disk for bad sectors  is a good utility to run. Run as scan only or run as scan and fix. We can run through a command line through terminal or graphical interface. 

Recovery Image – is a section of our hard drive dedicated to a factory restore image.  Wipe out all we did. Run recovery takes back to out of the box.  Remove pictures and all additional items that were put in.   Other tools will need to be run so it can be passed on.

Defrag- Organizes and data more contiguous.  Defrag can be scheduled.  Tell it to scan to see how much is fragmented.   Don’t preform a defrag on a solid state drive.

Tools for preventative maintenance – Keeps computer up to date.  Keeping the computer running smoothly.


Backup tools – different operating systems.  Each tool has different capabilities.

xp is nt backup allows to save files and folders but if we needed to create an  actual image backup then we would need to create an image backup using 3rd party software

Vista we would use our backup/restore center

Windows 7  we would use backup and restore(files, folders and computer image.

System restore tool – Allows to create restore points. Does not delete, restore point or change any of our files and folders.  Can be good if we created a restore point.  System restore is not an antivirus.  It will not completely remove virus. The malware will still be there. Files and folders will still be there with the malware.  System restore will not change or remove that file or folder. It will just revert some of the settings.

Check Dsk command – chk dsk allows to scan hard disk for bad sectors or corrupted files or sectors that we want to recover we can run as scan only or scan and  fix .

Can Run through command line or run through a graphical interface.

Recover Image is a factory restore image.  Clean slate by running factory reset.  Deletes pictures, documents etc. is not a secure way to wipe  to sanitize to give to someon else.  

Defrag organizes fragmented data.

Do not run a defrag on a solid state drive


NotepadSoftware & Driver/Firmware

Software updates & Drivers -hardware specific 

Can roll back drivers go back to previous driver.

Driver properties will allow you to rollback.

Firmware – Bios, Firmware on devices that may function in properly and may need to have update.  Firmware controls and  manages the hardware.  If not installed properly it is Bricked.  Avoid bricking device may not to recover or may need to send back to company to be re-setup.  Firmware is hard coded and may need to be updated by manufacturer.  May need special tools to re-brick the device.

Windows updates are not the only updates needed.

Other updates like Java, Adobe, etc will let you know when it needs to be updated.
