Tip 1 – Set Windows Password
As far as I am concerned, not everyone likes setting a password to his or her Windows computer. At least I noticed that quite a lot of friends think it’s pretty annoying to enter the combination each time Windows is started. But this will be the primary risk you put your PC privacy in. For example, if you carelessly lost the laptop or stolen by a thief, you are losing more than just a computer, but all your privacy within uncovered. You never know who will use your computer. So pretty straight forward – set a password for your operation system and give your privacy the first lock.
Tip 2 – Make Backups Regularly
Backup has been proven to be the most effective way to prevent data loss. That's the reason why online data backup software such as DropBox, Google Drive are so popular nowadays. But if you are used to those software, buying an external hard drive is the easiest way. Just be a little bit diligent and make several more copies of your important papers or precious photography.
Tip 3 – Install a Data Recovery Tool just in case
If you are used to emptying the Recycle Bin or use other methods (such as Shift+Del and format the device) to get rid of files you don’t want, but later found yourself often make mistakes and also erased those valuable files. In this case a data recovery utility is recommended to be kept on your desktop as this kind of deletion or format is another word to make files “hidden”. Recuva is the best freeware data recovery software I strongly recommend for you.
Tip 4 – Prepare a File Shredder or Drive Wipe Utility
For those who want to delete files or folders permanently and make them beyond recovery even with data recovery tools, file shredders or data erasers come right to help. Even more if you want to donate your hard drive or clean the HD completely, a drive wipe utility is a must. These kinds of wipe apps are absolutely powerful to make data really gone forever.
Tip 5 – Clean Registry in Time
Registry cleaning means a lot to both your PC performance and privacy security. Every singer movement you do with your computer is recorded to be history (or footprint), including caches, cookies, search history, temporary files and more. With the passage of time, those footprints may take much disk space thus make your computer run slowly and far more important it records too much of your privacy. So getting rid of them is a must-do job in time if you don’t want them to be seen by others. As to the cleaning too, CCleaner is the best one I’d recommend. This program not only scans for those records, but also provides secure delete (means erase them permanently like file shredders do).
Tip 6 – Password Protect Disk or Files
As I said in tip 1 setting Windows password is the primary lock for your privacy, so password protecting a disk or file is the second lock. There are many freeware data encryption software out there. Some can encrypt a file or folder to .exe with password open, while some others are able to create a personal safe area on your partition (secured with password too). Those passwords you set are extremely hard to break unless you are the engineers who design them.
Those are the 6 tips I have that may help you make your PC privacy secure, there should be more helpful tips or freeware out there. If you know some, please share.
