The following folders need to be backed up:

  • C:\Users\[user name]\Desktop\
  • C:\Users\[user name]\documents\
  • C:\Users\[user name]\pictures\
  • C:\Users\[user name]\Documents\
  • C:\Users\[user name]\Downloads\

If you use an email program like Outlook Express, MS Mail, etc., then you should export all your emails and address book entries to some safe place so that you can recover them afterwards. You can take backup of all the mails in the Inbox, Sent Items, Outbox and Drafts, unless you think it’s not required.

Take backup of the bookmarks on your web browsers by using the export bookmark feature of your browsers. You can easily export bookmarks and then import them to your favorite browsers after reinstalling Windows. If you are using special settings and add-ons on your web browser, then make a list of these details as well.

Therefore, make a list of all the programs, which are currently installed on your computer, so that you can reinstall them afterwards.

While taking backup you can create an Excel spreadsheet for storing this information. Benefit of using an Excel spreadsheet is that it can be password protected, which is necessary for securing such sensitive information. However, if you want to open Excel file after reinstalling Windows, then you will have to install MS Office before you could open that file. Using WordPad or Notepad can be risky as you cannot secure such files with a password.    

If you don’t have Excel installed on your computer, then you can use a piece of paper to note down all the usernames and passwords.

6. Drivers for Hardware (Optional)

There are a core set of drivers that you will have to install on your Windows depending upon the hardware installed on your computer.

If you are upgrading your Windows, then make sure that the drivers you are collecting as backup are fully compatible with the new Windows version you will be installing.

7. Service Packs (Optional)

If the Windows you are using has its latest service packs installed, then you must take backup of that service pack before reinstalling Windows. You can get the latest service pack for your Windows by using Windows Update, from Microsoft Website, through CD/DVD, etc.
