A Quick Guide to Fixing the Stop C00002lA Fatal System Error

Stop C00002lA Fatal System Error- What is it?

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down. The stop C000021A error message is displayed in the following format:

Stop c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.

Error Causes

The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen. Here are some of the underlying causes for the stop C0000021A error:
  • The incompatible third-party program
  • Hard disk issues
  • Service pack installation has failed
  • Mismatched system files have been installed
  • Bad and invalid registry keys

Further Information and Manual Repair

To resolve the stop C000021A Fatal System Error on your PC try the following solutions:
  • Remove Incompatible Third Party Programs

If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program. To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list. Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.
  • Repair and Restore the Registry

This procedure is slightly long and tricky. To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT. Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive. Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST. Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1. This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002. Now locate the following registry key: HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open. Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys: HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation. This will resolve the stop C000021A error.

Combine Hard drives with storage spaces
Why combining hard drives with storage spaces? Ok, I will admit it, I am a modern digital hamster when it comes to digital goods. I like to collect stuff and more than anything else I like to have all of that at the tip of my fingers. And how digital goods grow in size themselves (movies on Blu-ray are like 50GB each) and the collection grows in size single hard drive is starting to be completely obsolete when it comes to storage. Sometimes we will need large storage for these kinds of personal collections, sometimes we will need it for work reasons. Whatever your reason might be Windows 10 is offering us a solution via Storage spaces. Storage spaces is an integral part of Windows and it is meant as a tool to provide you with a RAID environment without a RAID controller. Of course, combining multiple hard drives via storage paces instead of RAID will not be so fast or stable but for home use of storing a large quantity of data is perfectly enough. With Storage Spaces you will also have an option to reduce some space for increased security of data loss if by any chance one of your HDD fails.

How to Create a Storage Space

To create storage space in Windows, press ⊞ WINDOWS + R to open the run dialog. keyboard with windows and r markedIn the run box type in Control Panel and press ENTER run dialog with control panel typed inIn Control Panel find Storage Spaces and left-click on it. Control panel with storage spaces markedOnce storage spaces open, left-click on Create a new pool and storage space storage spaces manage storage spacesOnce you click on create new, you will be greeted with a list of hard drives you can use for this operation. storage spaces select drivesPlease note that all hard drives you choose will be completely erased and formatted and then assign a single drive letter. Click on Create pool. storage spaces resiliency type optionsYou will find yourself in new storage options where you can assign a drive letter, give storage space a name, etc.

Storage spaces types

One thing I would like to focus on here is resiliency type, when you expand the resiliency type drop-down menu you will see 4 options inside. Simple, Two-way mirror, Three-way mirrors, and Parity. Simple: If you choose Simple as an option, you will have maximum hard drive space but no resiliency at all, meaning that if by any chance any of your hard drives malfunction, you are losing your data from that drive completely. Two-way mirror: This option will save your data if one of your drives fails but you need at least 2 drives and storage space will be limited since some of it will be a safe backup option for the case of a drive failure. However if one of your drives fails, you can replace it in a second and keep on working as nothing happened. Three-way mirror: This option similar to the previous one will offer you safe data-keeping from a hard drive failure. this option will save your data even if 2 hard drives malfunction but it will require having 5 of them connected in order to be able to choose this option. Parity: Maybe the most popular option among people who want to have 2 or 3 drives merged but do not want to lose too much space of the two-way mirror option. It offers some protection and it does not take so much space as two-way does, let us say it is a kind of win-win situation.

Conclusion

I personally go for simple and have an important backup on optical drives but only for reason I could use more space, know that this way is requiring from me to always have a backup in optical media and that I will need to restore all of it back if even one HDD fails which could take time. But if this way is ok with you, go for it, you will have more space to use.

Removing Search.schooldozer.com hijacker

What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do.

This is in contrast to what it states in its Privacy Policy:
“Install applications the easy way and without the hassle, using the Schooldozer downloader. The Schooldozer platform stems from years of experience with installing applications, resulting in a highly optimized process, yielding faster downloads, better user experience, and more successful installations.”

ERR_CERT_COMMON_NAME_INVALID error in Chrome
In case you don’t know, when you visit a website that uses HTTPS, it also offers an SSL certificate to the browser in order to verify the website’s identity. Although it may contain lots of things inside it, one of them is the URL of the website. So if the certificate does not match the URL to what you entered, you will most likely get the “Server’s certificate does not match, ERR CERT COMMON NAME INVALID” error which indicates that the connection is not private and the site may try to steal your data but worry not, as this post will guide you in resolving this issue.

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.
