Error 1753 - What is it?

Error 1753 is an RPC endpoint mapper error code. This code is typically displayed as "EPT_S_NOT_REGISTERED" or sometimes as the hexadecimal value 0x6D9.  Error 1735 indicates that there are no more endpoints available from the endpoint mapper. To understand this better, basically, RPC is an inter-process communication (IPC) method. This is used by clients and servers for communication purposes. RPC is used by programs to execute programs on a server computer. The perfect example of this is Microsoft Outlook. You communicate with Microsoft Exchange Server using RPC. This enables you to send and receive emails. When you use Microsoft Outlook to send emails, your computer sends a message to the server computer in an obscure coding. The server responds to your computer with another message that contains the results of the executed program. This is all being carried at the backend of the running program. Integral to this is the endpoint. The endpoint includes the name, port, or a group of ports on a computer that is monitored by the server for incoming client requests. This is a network-specific address to be precise. The endpoint mapper is the part of the RPC subsystem that is responsible for dynamically assigning endpoints to the server. When this function fails it leads to error 1753 message display. It shows that RPC service is not available.

Solution

Error Causes

The error code 1753 indicating RPC endpoint mapper service failure is triggered due to multiple reasons. These include:

• Windows registry damage and corruption
• Malfunctioning of the hardware
• Spyware intrusion or viral infections
• Device driver conflicts

There are times when you install a Windows update to your Windows 10 computer but you only got an error message saying, “The update isn’t applicable to your computer”. This is unusual as Windows was the one that downloaded them in the first place. To understand the reason behind this error, read on as this post will also give you a couple of suggestions you can try to fix the problem. One of the main reasons why this error occurs is that your computer might not have the required installed updates and many more. Other reasons include:

1. The update might be replaced. There are instances when a newer Windows version is already available on the computer and that the version you are trying to manually install is an older version which is why the Windows update failed.
2. The update might already be installed. There are times when the update process is still in progress and the earlier payload might have already been installed.
3. It could also be that it’s a wrong update for architecture. As you know, updates are designed accordingly based on the architecture of the computer so if the update you are trying to install does not match the architecture of your CPU then it’s no wonder you’re getting an error message.
4. Your computer might be missing a prerequisite update. There are Windows updates that depend on other updates so if you missed one and you’re installing another one, it could be the reason why you’re getting the error.

To fix the problem, here are some suggestions that might help.

Option 1 – Try verifying the package and the Processor Architecture

As pointed out earlier, updates are made according to the Windows versions. Thus, if one of the updates failed to install, you need to check if it’s applicable or not. The best way to do that is by searching the Windows update name on the official website of Windows. It could be that the Processor Architecture is not compatible with the Windows Update you are trying to install. If you have an X86-based processor, you can’t install x64-based installations of Windows and vice-versa. This usually happens when you’ve downloaded the update manually and then tried installing it.

Option 2 – Try checking if the update is old

The issue might be because you are trying to install an old Windows update which is why it didn’t work. To check, go to Settings > Update and Security > View Update history. From there, you can look for the update.

Option 3 – Try checking if the update is already installed

To verify the update, just go to the Windows Update history once more as you did in option 2, and then see if the update is already installed or not.

Option 4 – Try checking the prerequisites

AS mentioned earlier, there are some updates that depend on other updates before they get installed on your computer. The best way to verify is by checking the Microsoft Knowledge Base (KB). And to verify if the prerequisite updates are installed or not, just run the command below in PowerShell:

get-hotfix KB1111111, KB2222222, KB3333333

Note: In the command given above, you need to replace “KB1111111, KB2222222, KB3333333” with the actual update KB numbers.

Option 5 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

• Go to Settings and click on Update and Security.
• From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
• After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses?

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.

What Does 0x8007045D Error Code Mean?

The 0x8007045D error code is an I/O (input and output) error that is associated with the registry. It indicates that the Windows operating system has become overloaded with invalid system references in the registry. This may prevent you from executing reading and writing to and from devices successfully.

Error Causes

Registry is the main database of your PC. This portion of your computer saves all the activities that you perform on your PC including the junk files, temporary internet files, invalid entries, bad registry keys, and more. This clutters the hard disk. If the unnecessary files are not removed from the registry, it may lead to I/O errors like 0x8007045D. On the hard drive, some parts of the drive may fail to function. If this is not fixed on the time it may lead to serious disk damage and registry corruption eventually resulting in system failure. System failure can make you lose all the valuable data saved on your system for good.

How to Fix the Error Code 0x8007045D?

Error codes on your PC are like warnings. These codes indicate that your PC has some issue. Therefore ignoring it is not wise. To spare yourself from such serious PC damages, it is advisable to take correct measures timely instead of prolonging and making the situation go from bad to worse.

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin. However, there are some servers that don’t have an associated MIME type to support MP4 files and so they fail to play these files. In such cases, you will encounter the “Unsupported video type or invalid file path” error, especially when you use the Internet Explorer browser in Windows 10.
