With todays nasty and destructive malware, I suggest you backup the registry everyday and apply the tweak that I explain below to change the number of backups that are saved.
Another benefit of having ERUNT installed on the system is that it keeps a cache of many important system files.
You can add the tweak even if you already have ERUNT installed.
The process to backup the registry is very quick and you won't even notice it!
Registry Backup and Restore for Windows NT/2000/2003/XP/Vista/W7
"ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed."
Here's how to backup the registry using ERUNT:
Vista and Windows 7 users: use (Right click, choose "Run as Administrator") when running .exe files.
You can find information on ERUNT HERE, please read through it.
(WIN98 and ME users....the registry is automatically backed up...no need to install ERUNT, check HERE on how to restore a copy of the registry)
Please download and install ERUNT using This Link
Double-click erunt_setup.exe to run.
Follow the prompts and install using the default configuration including adding ERUNT to the Startup folder.
Vista and Windows 7 users check HERE and HERE on how to configure auto backups.
Adding the tweak still applies though.
**The problem with Vista and W7 is the User Account Control (UAC), it blocks the running of ERUNT.
Turn it off and the default way of making backups will work....that's up to you though.
Here's the ERUNT Installation Tutorial w/pix
After you install ERUNT and have created a backup of the registry, apply this tweak:
This is for XP
By default ERUNT will save the last 30 copies of the registry, this is not needed.
Go to your Start button > Programs > Startup > Shortcut to AUTOBACK.EXE
Right click on > Shortcut to AUTOBACK.EXE and click on properties
The Target should already be highlighted
Right click on it and choose Copy
Paste it into notepad or Word, it should look something like this: (the path may be different on your computer)
"C:\Program Files\ERUNT\AUTOBACK.EXE" %SystemRoot%\ERDNT\AutoBackup\#Date# /noconfirmdelete /noprogresswindowNow add this to the end: /days:3
noprogresswindow /days:3 (note the space between w and /)
The number indicates the number of backups being saved, you can set it to what ever you want, 3 to 7 sounds good to me, make it more if you want.
It should now look like this:
"C:\Program Files\ERUNT\AUTOBACK.EXE" %SystemRoot%\ERDNT\AutoBackup\#Date# /noconfirmdelete /noprogresswindow /days:3Go back to the Shortcut to AUTOBACK.EXE, the Target should already be highlighted > hit your delete key > now copy and paste in the new target you created.
Make sure the Run: box says Minimized > click Apply and OK to close it out.
These automatic backups are stored in the C:\WINDOWS\ERDNT\AutoBackup folder.
Now the registry will be backed-up every day and available if needed.
If you already have ERUNT installed and you want to add the auto-backup, here's how to do that:
Navigate to the ERUNT folder (C:\Program Files\ERUNT)
Right click on AUTOBACK.EXE and choose Send To > Desktop (create shortcut)
Now copy and paste the shortcut into the Startup folder
To get to the Startup folder: Go to Start > Programs > double click on Startup
You'll have to add the Target:
"C:\Program Files\ERUNT\AUTOBACK.EXE" %SystemRoot%\ERDNT\AutoBackup\#Date# /noconfirmdelete /noprogresswindow /days:5The Start in: box should say: "C:\Program Files\ERUNT"
Note: to restore your registry, navigate to this folder......
C:\WINDOWS\ERDNT\AutoBackup\(date) <----with auto backup
C:\WINDOWS\ERDNT\(date) <----without auto backup
and run ERDNT.exe
Good Luck, MrC
