The best idea is not to let your son your computer at
ALL! Get him a different computer, perhaps an older refurbished computer or laptop he can use for schoolwork or entertainment.
If that's not possible, some suggestions are:
1.) Do
NOT give him a Microsoft account login; instead create a
LOCAL login on your computer if you haven't done this already with the account you mentioned you created for you. This will keep him from purchasing any kind of apps you are not aware of with your Microsoft account that has full access to the Microsoft online App store and any Credit Card information you have stored there.
2.) Use the Microsoft Family application kemical mentioned.
3.) Use the Family protection accounts that are free from major antivirus makers such as
Norton, Avast, and McAfee. Most of these can be downloaded from the antivirus maker's software site for free and are general included in the Internet Security Suite versions of their software. They used to give that module to you free and you just turn it on in the App User Interface. But, not they have you create an account to register your Software and then they let you download the Family protection module for free and give you usage instructions to view/download/print.
4.) Consider using a 3rd party Parental Control software such as
K9 Web Protection. This is an excellent software and with a little time and patience you can keep your child from ever seeing any kind of gambling, porn, or violence-propagating sites that you may inadvertently visit on your account. They use an advance learning AI that is quite similar to the one in Microsoft's Family Protection and the AV Maker's Parental Control add-on apps. I've installed this on a couple of Client's who wanted their child to have Internet access but were concerned about them seeing or visiting bad or questionable sites. Age group of 8-17 is targeted for various levels of non-access. This is the best one I've yet see. After visiting the Client's site on follow-ups, zero bad sites were accessed, yet several up to hundreds of bad sites were attempted by the Child. Child only sees a Restricted error message telling them they cannot access a particular site without their Parent's permission.
Personally, I haven't used Microsoft Family protection either, as kemical mentioned; but I have experience with #3 and with #4 and they are both really good. In fact, one computer I did for a 12-year child of a Client I used both #3 & #4 to really lock down the computer. These programs actually wrap the Child's Microsoft account as well as your Microsoft account in protective "wrappers" that block out bad sites at the kernel OS level of Windows and also use ACL along with AI methods to do so; the best personal account security available on the market today
. This way, if your Child brings a friend or school-mate over who's more computer "literate" or is a "hacker", these softwares will defeat them from getting access to your account and seeing what you have or access. Of course, there are 12 year olds who have hacked government computers, so no system is 100% safe.
And, no system is a substitute for parental supervision.
I recommend to my Clients that absolutely no Child should be left alone in their room with a computer with Internet access under 10 years of Age and the door closed or locked!
It's vital that you as a parent take responsibility for monitoring and checking what your Child does on the computer, where he goes, what sites he visits, and what time of the day/night he/she does so. The software mentioned above help you do this, but don't take over your job of monitoring and guiding in any way; they are tools to assist you in that job, not "bot-replacements".
If you implement some or all of the above precautions and they still get through your security protection, possibly through a knowledgeable friend or school-mate, or older teenager, it's time to get them off your computer for good and get them onto their own computer that you can properly physically secure and monitor.
Penalizing them for a period of time, whether weeks/months/years is also something to consider if they breach your computer security. Cyber-parenting 101 there.
Hope this proves helpful to you.
