I've run into this situation more times than I care to remember: A friend calls upon my aid because he's messed up his PC by unknowingly installing programs that, while they may not technically be termed "malware," nevertheless slow down the machine or cause it to start misbehaving in one way or another. Of course, a good option is to boot up with a security program like the one included with most antivirus suites. An excellent way to fix the problem is simply to restore the friend's PC to an earlier working state.
That's exactly what Restore Points let you do.
And they don't affect any documents, photos, email, or other data files that you acquired more recently than the restore point — only the system and programs. That's a key difference between creating a full disk image backup — which also reverts your personal data files to the earlier state.
If a PC user has created a Restore Point within a reasonable timeframe — say, the last couple of months — you can usually get the sick machine back in tiptop shape by running System Restore.
Windows automatically creates restore points when a new program or system update is installed, so there's a good chance that you'll be able to revert to a good state even without any forethought.
But just to be safe, let's all create a Restore Point today. And do this the next time you're visiting your novice PC user friends. The small bit of effort it takes will most certainly pay off when it comes to much simpler troubleshooting sessions at later date.
