New Windows vulnerability discovered

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system.

The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges.

The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control.

Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.

Using ???? and other emoji in Windows
Did you know you can use emoji in file names inside Windows 10? It is no secret that emojis are basically everywhere and Microsoft has seen this and integrated them into Windows itself, so you can name files using emojis or combine them with text. Placing emojis in file names or in the text is extremely easy, all you have to do is press ⊞ WINDOWS + . and the emoji dialog will open from where you can find which emoji you would like to use. And that's it, you just used emoji for the file naming.

!!!NOTE!!!

In theory, some applications may not like these emojis if they don’t support Unicode characters. However, modern applications are designed to work with a broad set of languages that should properly support emojis. For example, the classic Windows Command Prompt can’t see emoji characters in file names properly, but both PowerShell and Microsoft’s new Windows Terminal can display them properly. If you do run into a problem, you can always open File Explorer and rename the affected files and folders to remove the emoji characters. You can then use those files in applications that don’t properly support emoji file names.

The PrintNightmare vulnerability finally fixed
PrintNightmare vulnerability has been a struggling issue for Microsoft in the past weeks, each time it seems to be addressed and fixed something new popped up and it still had issues. Microsoft finally addressed the issue but with a price. The default behavior of Point and Print is changed. From this fix onward, the Point and Print driver installation and update behavior will require administrator privileges, which should prevent the exploit to the Windows Print Spooler that could be used by malicious individuals to gain administrative privileges in Windows. The drawback of this fix from Microsoft is that non-elevated users may have difficulty adding or updating printers. Microsoft feels that the security risks caused by PrintNightmare are worth the tradeoff, though. If you really want to let non-elevated users add printers, you can follow the instructions in this Microsoft Support article to disable this mitigation with a registry key. However, doing so will expose you to this known vulnerability and isn’t recommend.

Should you buy used GPU in current market?
Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU? Short answer: NO, long answer: keep on reading to find out why.

GPU 1080tiGPU shortage and its cause

As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised. Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage. Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world. Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.

Be prepared for the worst scenario

Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU. What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked. Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks. There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.

Age of the GPU matters

Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action. Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state. On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.

No return policy and seller rating

Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase. Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store. Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.

If you really must buy a second-hand GPU

Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU. In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is. Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.

Conclusion

It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.

Fix user account is not authorized
If you encounter an error message saying, “The connection was denied because the user account is not authorized for remote login” when you try to establish a remote connection, read on as this post will help you resolve the problem. This kind of error occurs when the targeted host does not allow you to access that system remotely. Based on the error, you are not authorized to log in remotely which means that you need to obtain the correct permission. There are several potential fixes you can try for this error. You can try to check the Remote Desktop Users group or add users to the Security group or check the Remote Desktop Service itself. Refer to the options provided below for more detailed instructions to fix the “The connection was denied because the user account is not authorized for remote login” error.

Option 1 – Try checking the Remote Desktop Users group

You can encounter this error when the Remote Desktop Users group does not have any permission for your user account that you are using to establish a remote connection. Thus, you need to make sure that your user account is a member of the Remote Desktop Users group. How? Refer to these steps:
  • Tap the Win + R keys on your keyboard and then type “cmd” in the field and tap Enter or click OK to open Command Prompt.
  • After opening Command Prompt, type the “lusrmgr.msc” command and tap Enter to execute it.
  • Alternatively, you can also search for “lusrmgr.msc” in the Start Search and once you’ve opened it, select Users and then double click on your user name to open its Properties.
  • From there, switch from the “General” tab to the “Member Of” tab.
  • Next, if you can’t see any Remote Desktop Users group under the Administrator, you have to add it. To do that, just click on the Add button.
  • After that, on the newly opened window, click on the Advanced and Find Now buttons, respectively.
  • And in the Search results box, double click on Remote Desktop Users.
  • Now click on the OK button to save the changes made and check if you can now connect to a remote host or not.

Option 2 – Try to add a user to the Security group

You can actually block or allow a user from logging on through the Remote Desktop Services. However, if you do not have the right setting, you won’t be able to use this functionality. Thus, you need to confirm this setting. To do that, follow the steps below.
  • In the Start Search, type “secpol.msc” in the field and tap Enter to open the Local Security Policy panel.
  • From there, go to User Rights Assignment.
  • Next, look for a policy named “Allow log on through Remote Desktop Services” located on your right-hand side and then double click on it to open its Properties.
  • If you were not able to find the Remote Desktop Users under Administrator, then you have to add it by simply clicking on the Add User or Group button.
  • After that, enter “Remote Desktop Users” in the blank field and click the OK button to save the changes made.
  • Now restart your computer and try connecting again to the remote host.

Option 3 – Try checking the Remote Desktop Users group

There is a service that’s supposed to be running and needs to be set up correctly for you to connect to the remote host. And so you need to ensure that this service is up and running. To do so, follow these steps:
  • Tap the Win + R keys to launch the Run utility.
  • Then type “services.msc” in the field and hit Enter or click OK to open the Services Manager.
  • Next, look for the Remote Desktop Services and double click on it to open its Properties.
  • After that, go to the “Log On” tab and select the “This account” option and then click on the Browse button.
  • On the next screen that appears, look for the Advanced button and click on it and use the Find Now button to search.

Fix Windows Update Error 0x80240020
There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade
Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

Other Windows 10 error messages include error code 0xc000021a.

Solution

Restoro box imageError Causes

Your blinking or flashing desktop after logging in might be the result of problems with the bushell.dll shell extension, which is a part of the Norton Security Suite. Another possible cause for this annoying problem is an issue with your display driver since not all systems will use the same display driver and will depend on what graphics card you use.

Further Information and Manual Repair

In fixing the bothersome blinking or flashing desktop after logging in problem, you can do a manual repair method to address the root problem. You need to be familiar with the Windows command line to successfully go through the process. However, if you are not knowledgeable or confident enough to do this on your own, it would be best to seek help from a professional. Or, you might want to consider using an automated tool to solve the issue.

You need to identify first what’s causing the blinking or flashing of your desktop after login to properly address the issue. The following methods can be done if your issue is caused by bushell.dll shell extension issue:

  2. Start a Command Prompt as an administrator by choosing the File menu then Run New Task.
  3. Type exe. Make sure to tick the checkbox “Create this task with administrative privileges.”

NOTE: Text input is most probably affected by the explorer restarts so you might need to repeatedly type some letters or to carefully input texts.

  1. In the Command Prompt, type taskkill /f /im explorer.exe. This will stop the blinking or flashing.
  2. Type cd “Program Files” afterward, type dir /s bushell.dll to locate where the dll is. (For example, purposes, use c:\program files\Norton Security Suite\Engine6422.5.2.15 as the location)
  3. If the dll file is not found, you can try repeating step 5 but this time, use “Program Files (x86)” However, you can proceed with the next step if you already located where the bushell.dll is.
  4. Type cd ”c:\program files\Norton Security Suite\Engine 6422.5.2.15” to change the name of the directory you found the dll in.
  5. Type ren bushell.dll bushell-crash.dll
  6. Restart now the system by typing shutdown /r /f /t o in the command line.

Method Two: Uninstall Programs

  1. Log out then go to the sign in screen
  2. Press the Shift key as you simultaneously click on the Power button on the screen.
  3. Continue pressing on the Shift key as you click
  4. Continue pressing on the Shift key as you wait for the Advanced Recovery Options menu to appear.

  2. Press the Shift key as you simultaneously click on the Power button on the screen.
  3. Continue pressing on the Shift key as you click
  4. Continue pressing on the Shift key as you wait for the Advanced Recovery Options menu to appear.

  10. Click on the Services tab then choose Disable All. Afterward, click on
  11. Once you’re prompted to reboot your computer, go ahead and reboot in Normal Mode. Check if the issue is still present.
