Windows 7: How roll back windows without reinstalling it.

I am tired of reinstalling Windows every time due to viruses and slow down on PC.



I read some where that there are softwares called 'disc imaging software' or something that can restore windows back to the way it was when it was installed (Freshly installed windows) .

Please suggest me a good software for this.

Windows 7 has it's own built-in imaging tool.

Backup Complete Computer - Create an Image Backup

Some folks find this tool to be very limited in what it can do so they use other free imaging programs like:

Macrium

Paragon

EaseUS Todo

And still others use the paid versions because of even greater versatility.

One scenario is to do a clean install of Windows 7, install an anti-virus suite of choice, and then install all Windows Updates. Once that's been done, make a system image and save it to an external hard drive. Install any other programs, applications, etc that you use and make a second system image. Then, set up a schedule that suits your needs for additional backups of only new user data and a schedule for additional system images.

I think most people recommend saving backups and images to an external hard drive just because they are more reliable than disks, they have a greater storage capacity, and in the long run it's cheaper to buy a 1TB external hard drive that an equal number of DVDs ( about 225 DVDs that are able store about 4.5GB per disk.) Also, if one disk fails to burn properly the entire set of backup or image disks becomes useless.

Imaging with free Macrium

I see. Can you recommend me a linux distro that does the same as the above software (Macrium, Paragon) ? It should have both backup and restore features.

All of the different variations of Linux such as Ubuntu, Knoppix, Mint, etc are operating systems just like XP, Vista, 7 and 8 are variations of Windows operating systems. I might be completely wrong on this but I don't believe any of the Linux distros incorporate a backup or imaging capability because of the many free software programs like Clonezilla, Macrium, Paragon, etc that are available. If I misunderstood your question my sincerest apology.

I meant I want a recommendation of a cold backup linux distro like clonezilla, PING etc

A quick google:

Partimage

However, for imaging Windows OS I would recommend the suggestions made earlier.

Unless they updated it, and the last time I checked, they said they were NOT going to update it, PartImage (which PING uses) does not work with Ext4 filesystems -- which is the default filesystem that several Linux distros have used for years. Better solution in the Linux world (and the one I use) is Clonezilla. If you go to their website and do some reading, there is a way to install Clonezilla to your hard drive so you can boot from that, instead of having to burn a CD, or write a USB, and boot from that.
