System Restore may not work if anti-virus software is preventing the program from creating a restore point, or if third-party drivers have interfered with the restoration process. System Restore also requires 300 megabytes of hard drive space to store restoration points.Continue Reading
One of the most common reasons System Restore fails to work is the feature not being enabled on all hard drives. System Restore must be enabled on any hard drive that the user wishes to restore at a later date.
It is also common for drivers and system services to prevent restore points from being created. This is usually only an issue with drivers that aren't made by Microsoft. To check whether drivers are causing a problem with System Restore, try creating a restore point after booting into safe mode. Safe mode only loads essential features of Windows. If there is an error in the hard drive data, this can prevent System Restore from successfully creating a backup. Errors can often be fixed by running the Check Disk program in Windows.
Another potential reason for System Restore not working is that the system administrator has disabled it on all accounts. The only solution to this is for the administrator to manually re-enable it.Learn more about Computers & Hardware
