System Restore is a component of Microsoft’s Windows Me, Windows XP, Windows Vista and Windows 7, but not Windows 2000 operating systems that allows for the rolling back of system files, registry keys, installed programs, etc., to a previous state in the event of system malfunction or failure.
System Restore backs up system files of certain extensions (.exe, .dll, etc.) and saves them for later recovery and use. It also backs up the registry and most drivers.
The following resources are backed up:
- Files in the Windows File Protection (Dllcache) folder.
- Local user profile.
- COM+ and WMI Databases.
- IIS Metabase.
- Specific file types monitored.
System restores are normally created when software is installed using the Windows Installer, when Windows update installs a new update and there are so many other conditions. Don’t you think it must be vital function clipped with your software? Well, I dare say it must be! So, get the source code from below, and just do it.
Please note that this source code has been provided for Visual Basic .NET, which natively works with Microsoft Visual Basic 2008 and 2010 (including express editions).
Public Shared Sub RestorePoint()
‘Pointing to system restore
Dim restPoint = GetObject(“winmgmts:\.rootdefault:Systemrestore”)
If restPoint IsNot Nothing Then
‘Checking if its created successfully or not ‘Name of restore
If restPoint.CreateRestorePoint(“System Restore Test”, 0, 100) = 0 Then
‘Error message in the case of failure
MsgBox(“Operation failed, but you can still continue!”, MsgBoxStyle.Exclamation, “Ooops!”)
You must run this code in a seperate thread so that your software’s performance may not go negative. The tutorial for it goes here: https://hattedgeek.wordpress.com/2011/05/19/running-a-code-on-seperate-thread-or-background-worker-vb-net
