What is SuggestedSites.dat file? Problem in removing SuggestedSites.dat file from Windows 10

Old title: SuggestedSites.dat

I am running Windows 10 Pro, and have disabled Internet Explorer. I have a file, SuggestedSites.dat, that keeps appearing on my computer even after I run CCleaner to remove it, or go into the folder and delete it manually. It re-downloads itself within a couple of minutes of being deleted.

It can be found under, C:\Users\[my username]\AppData\Local\Microsoft\INetCache\Low\SuggestedSites.dat

Is this something that can be removed, or is it like everything else in Windows 10 that is forced on you, no option, and you are to dumb to make changes?

Does it perform some essential function that I am missing?

Brian

Windows 10 freezes up more than any OS I've ever had. Other than not working, it's not too bad.

Hello,

Thank you for posting your query in Microsoft Community.

Why you're trying to remove that file?

Does it causing any issues with your system performance?

Suggested Sites is an online service designed to suggest other websites you might be interested in based on the websites you visit most. This is accomplished by the file called SuggestedSites.dat. When you turn on Suggested Sites, your web browsing history is sent to Microsoft, where it is saved and compared to a frequently updated list of related websites. You can choose to stop Internet Explorer from sending your web browsing history to Microsoft at any time. You can also delete individual entries from your history at any time. Deleted entries will not be used to provide you with suggestions for other websites, although they will be retained by Microsoft for a period of time to help improve our products and services, including this feature.

You can disable this by turn Suggested Sites off in Internet options. Follow these steps to do the same:

  1. Open run command by pressing Windows Key + R, type inetcpl.cpl and hit Enter key.

  2. Under Internet options, go to Advanced tab then uncheck the option Enable Suggested Sites in Browsing.

  3. Click Apply and then OK.

With regard to Windows 10 performance issue, there might be some drivers or application might be degrading the System Performance. If your PC is running with Some third party Antivirus software then there might be changes that will cause Windows 10 to perform poor. Try disabling it for a moment and check if it works. Also ensure the your system is running with all compatible Windows 10 drivers. Check and confirm the same from Manufacturer website.

Note : Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it for any purpose, you should re-enable it as soon as you're done.

Keep your system up to date with all Windows Updates. Check and install all the available Windows Updates, if any pending out there.

If problem still persist,  then perform a clean boot in Windows and check if it works. A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program. Follow the below mentioned steps to perform Clean Boot:

a. Press Windows Key , type msconfig in the search box, and hit Enter.

b. On the Services tab of the System Configuration dialog box, tap or click to select the Hide all Microsoft services check box, and then tap or click Disable all.

c. On the Startup tab of the System Configuration dialog box, tap or click Open Task Manager.

d. On the Startup tab in Task Manager, for each startup item, select the item and then click Disable.

e. Close Task Manager.

f. On the Startup tab of the System Configuration dialog box, tap or click OK, and then restart the computer. Once you reboot your PC experience if any difference in performance.

Now it indicates that some other services are causing the issues. I suggest you turn on 5 services at a time which are disabled before, reboot and then see if the problem reappears, keep repeating this until you find a group of 5 services, which are causing this issue, then check the one by one, till you find the one which is causing your issue. Perform the same divide and apply for Startup's too.

Refer the below article on "How to Perform Clean Boot". As the article is designed for Windows 8.1, Windows 8 and Windows 7. Unlike launching step for 'System Configuration', options and steps to Clean Boot are same for Windows 10.

I have disabled Internet Explorer, but it keeps automatically downloading the file. This means that IE is not actually disabled. I don't like it when I delete/disable something and it doesn't do so. I don't need the file, so there is no reason it should auto install when I delete it.

I use the Windows Defender antivirus.

I've checked all the drivers and had Microsoft update them. Spent quite a bit of time going piece by piece on every bit of hardware.

The problem is sporadic (sometimes it is once every few hours. Just a few minutes ago it froze up 5 times in about 7 minutes).

I will try to disable all the startup programs and system configuration options as you suggested now.

Thank you for the response.

I see no "Enable Suggested Sites" option under "Browsing."

After disabling the programs it still froze up yesterday (too early to tell, but it seems it took longer before it froze). Now it does really long slow downs and then finally works again. When it froze I was running Firefox (Some web pages and music streaming) and Access 2013 (one file), plus the other 90 some background processes.

I am now attempting to test half at a time. The problem is sporadic. It could happen after 10 minutes, or 6 hours, of the computer being on, so narrowing each step down may take days.

I have all the non-Microsoft startup programs disabled, and all of the services disabled. Everything but Microsoft stuff is disabled. Had 3 slowdowns (Access stops working for about 2 or 4 minutes, music stops streaming, then both finally work again), and then it did it a 4th time and totally froze again.

I was running Opera and Access. So, it's not the browser (it does it with Firefox, Opera, and Edge running). I'm pretty sure I've had it freeze without Access running before too (just have to use it for work lately, which is being greatly disrupted). All the startup and non-Microsoft background programs are disabled (so it's not something I have installed).

I assume it must be Windows 10 being a terrible operating system. Windows 8/8.1/10 are amazing reasons to switch to IOS or Linux. IE11 and Edge/IE12 are really good reasons too. I really hope Microsoft would either start to listen (and I don't mean spying), or just finish destroying their company.

I'm so sick and tired of trying to deal with this defective product. Shouldn't this have been sorted out in Beta?

Hi,

As many other people who care more than everage about their computer I also stumbled upon this "SuggestedSites.dat" sticky file.

At first glance I was happy to see the advise "uncheck the option "Enable Suggested Sites in Browsing"! - but I beacame quickly disappointed when I saw it actually WAS already disabled !

I never use Internet Explorer, nor edge. In my opinion, native microsoft browsers are far behind what it should  be expected in our times. Just take a look at Firefox !

So anyway, as I see there is no way so far to get rid of this - for me absolutely useless - "SuggestedSites.dat" file.

Maybe, if you have a better idea, would you mind to make a more powerful suggestion, wouldn't you?

By the way, before you posted this fake hint,...

"You can disable this by turn Suggested Sites off in Internet options. Follow these steps to do the same:

  1. Open run command by pressing Windows Key + R, type inetcpl.cpl and hit Enter key.

  2. Under Internet options, go to Advanced tab then uncheck the option Enable Suggested Sites in Browsing.

  3. Click Apply and then OK."

... have you tried it out at all ?
