Privacy is a hot topic lately in all circles so naturally themes like private or incognito browsing pop up immediately as discussion topics. Naturally, when discussing private or incognito browsing it is very important to understand what exactly private or incognito browsing is, what does it do and how it works in order to shed some light on is it really private and safe as we are told. So, when you browse the internet normally websites have tendencies to save your browsing data, save cookies, remember passwords, etc in order to provide you with a better surfing experience next time you visit that same site. Private or incognito browsing treats you as a completely new user which is the first time visiting a given website. It clears all your data, including your browsing history, cookies, etc., on exiting. Every website you visit in private or incognito mode treats you as a new visitor, even if you have visited it before in incognito mode. And basically, that's it. So is it really private? No, it is just a non-remembering mode of internet browsing where after your browsing session history and other data is cleared from the browser, but while you are on the internet you are pretty visible to all like any other normal user. There are a lot of misconceptions and wrong thinking about browsing the internet in this mode so let's take a look at some typical ones.

1. The government and other companies can not track me

   Many people think that the Government cannot trace their identity when they surf privately. This is only a myth. There are many ways by which the Government can reach you if you do something illegal. When you surf online, you are connected with an ISP of your area, which helps the officials track your location.

2. Virus and other malware can not infect me while in private or incognito mode

   Many people think that private mode protects them from virus and malware attacks. It is not true because malware and viruses can enter your PC through a software download, phishing email, etc. To protect your PC from virus and malware attacks, you should have good security software.

3. My IP address is hidden when I am in incognito or private browsing mode

   This is not 100% true. If you search “What is my IP” in incognito and standard mode, you will get the same results. This means that websites can view your IP address in private mode also. Using a VPN would be a good option if you want to hide your IP.

4. I can not be tracked via ads

   Since cookies are deleted after exiting private browsing, many people think that ads cannot track them. When you surf in incognito mode, the browser saves cookies in a temporary mode, allowing ads to track you during your entire private browsing session.

5. I am not visible when I am in incognito or private

   You may think if you sign in to your Gmail or other social media accounts in private mode, no one will see you online. This is not true. It does not matter whether you have signed into your account in normal mode or incognito mode; others can always spot you online.

In your regular browsing mode, you may have some addons, extensions, themes, etc installed and you can use them. They may track your activities. The data is deleted when you exit the browser. When you use the private browsing mode, the browser is loaded in its original form, typically without the installed addons, extension, themes, etc. The data gets deleted when you exit the browser. This mode doesn’t save data to disk but keeps it in memory during the current session. If you are really concerned about your privacy we have articles about using DuckDuckGo and deep web where you can be sure that your browsing sessions are encrypted.

Raptor Lake, a new and upcoming Intel 13th generation CPU will break the 6GHz barrier for the first time ever in normal working mode, overclocked mode in Intel words will go as high as 8GHz. CPU will be 15% faster than Alder lake in single-threaded tasks and a stunning 41% faster in multi-threaded workloads.

The current world record for overclocking is 8.72GHz done with AMD FX-8370 and Intel is aiming at breaking that record with Raptor Lake, of course, this kind of extreme overclocking will require some top-of-the-line nitrogen cooling systems.

Raptor Lake will run on the current LGA 1700 socket, so you will not need to buy another motherboard for CPU and they will also be manufactured on a 10nm process which means that you will need to take care of cooling and power supply if they really go over 6GHz.

Mid-range Intel Core i5-13600K processor will come with 14 cores inside and 20 threads running at a maximum P-core frequency of 5.1GHz, while Core i7-13700K will have 16 cores and 24 threads and run on 5.3GHz max P-core frequency. Best i9-13900K will come packed with 24 cores, 8 of them will be P-cores, and the rest 16 are E-cores, and 32 threads. It will reach 5.4GHz frequency but it was stated it can go to 5.8GHz with Thermal Velocity Boost.

After this statement, we can clearly see that the 6GHz breaker CPU will probably be an i9 special KS variant. In other words, specially tested and picked existing i9 running at higher speeds as was with Alder Lake as well where normal i9-12900K ran at 5.2GHz while i9-12900KS was running at 5.5GHz.

Option 2 – Troubleshoot the missing Msvcr120.dll_clr0400.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the application again.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:WindowsSystem32
  • x64: This PC > C:WindowsSysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 5 – Scan your computer using Windows Defender
