This article was previously published under Q295299
This article describes how you can use the System Restore utility to create, enumerate, and restore previously created restore points by using Windows Management Instrumentation (WMI).
RequirementsTo run WMI, you must have administrator privileges. You can use System Restore by means of WMI and the Srclient.dll file.
The following VBScript code excerpts are minimal examples. This code must not be implemented without prior error checking and full testing.
To Create a System Restore Point
To Disable or Enable System Restore for a Particular Drive
To Enumerate System Restore Points on a Computer
The dates are returned in yyyymmddHHMMSS.mmmmmmsUUU format, where:
yyyy= a four digit yearNOTE: You cannot filter items based on specific dates. The filter process begins at the first restore points and enumerates from that location. If you want to filter items, you need to script a filter to narrow down the dates that are based on the values that are returned.
mm= a two digit month
dd= a two digit day of the month
HH= a two digit hour of the day (00-23)
SS= seconds (00-59)
s= plus (+) or minus (-) sign to signify the positive or negative offset from coordinated universal time (UTC)
UUU= an offset in minutes that the originating time zone deviates from UTC
To Roll Back to a Specific Restore PointNOTE: Do not use this function without also calling a computer shutdown. System Restore may not work properly if a restart of the computer is not initiated immediately.
