What does Windows System Restore do on your computer? Is it worth having System Restore on all the time, or is it wasting resources you could use?
System Restore runs quietly in the background doing nothing but monitoring your computer’s programs, system settings stored in the Windows registry; what files are on your hard drive and which have changed in some way. So it doesn’t consume much computer resources by running constantly. SO, you won’t gain performance by turning off System Restore.
System Restore saves your computer’s current state to a file called a Restore Point when one of the following events happens or is about to happen:
• When software is installed using the Windows Installer, Package Installer or other installers which are aware of System Restore.
• When Windows Update installs new updates to Windows.
• When the user installs a driver that is not digitally signed by Windows Hardware Quality Labs.
• Every 24 hours of computer use or every 24 hours of calendar time. Such a restore point is known as a system checkpoint. System Restore requires Task Scheduler to create system checkpoints. Also, system check points are only created if the system is idle for a certain amount of time.
• When the operating system starts after being off for more than 24 hours.
• When the user requests it.
In Windows Vista, copies created during File Backup and Complete PC Backup can also be used as restore points. Be aware that restore points can consume a healthy chunk of your hard drive.
By default, Microsoft Windows slots up to 15 per cent of your hard drive’s available space for the saving of restore points. When this space is filled with restore points, the oldest restore point is deleted on a “first in, first out” basis.
If your hard drive is getting close to being full, Windows may also delete some older restore points to free up space.
Changing the System Restore Disk Space Amount
• Click Start, then Control Panel. (On XP, select “Classic View”)
• Click System, then click System Protection (On XP, click System Restore).
• Select a drive and click the Configure/Settings button. A dialogue box appears that lets you
o Turn System Restore protection on or off for this drive.
o Set the percentage of disk space devoted to restore points
o Delete all stored restore points (Vista or Win7)
Remember, when using System Restore, programs installed since the last restore point was created will be lost.
System Restore can also be a way to get rid of malware but, it is not an effective measure. Frankie On Call can help with your virus and malware removal.
