McAfee Support often hears from people who are experiencing PC technical issues that could have been prevented by taking one easy step. 

Create ‘Standard (limited)’ user accounts on your PC, and use those instead of an ‘Administrator’ account whenever possible. 

The ‘Administrator’ account has full control over the PC, and changes made by the Administrator affect all users of the PC.  The ‘Standard’ account, with only a few exceptions, can do everything most PC-users need to do on a regular basis.  For many reasons, you should surf and work on a ‘Standard’ account, only jumping to Admin mode when its necessary, for example, when you need to install a new program.

Microsoft recommends standard accounts be created for every user of the PC, to prevent users from making changes that affect everyone who uses the computer, such as deleting files required for the computer to work.

But there is more to this story.  A lot of malware wreaks havoc on PC’s when it infects one while logged-in under an Administrator account.  Why?  With Administrative powers at your disposal, as mentioned earlier, the changes made to a PC will impact not just the Administrator account, but all other Standard accounts, too.  If you get infected while on a ‘Standard’ account, the impact of the infection will often-times only be felt by this particular user. 

I’ve created a short video, showing how you create a new Windows ‘Standard’ account.  Create one of these for every member of your household, and your chances of having a PC-destroying incident are greatly reduced.
