Solution

Error Causes

Error Code 0xc00000fd can arise when program files are not recognized properly by the operating system, when the operating system is no longer compatible with the program being run, when files are missing or corrupted, or when the program has been changed in a substantial way. Each of these causes requires a different method of resolution.

Further Information and Manual Repair

Several methods can be used to attempt to resolve Error Code 0xc00000fd on your computer. Basic users can use some of these methods, while others require familiarity with advanced tools and options in Windows. If you have trouble implementing the steps below, contact a qualified professional to assist you. Here are the top ways to deal with Error Code 0xc00000fd on your machine:

Method One:  Check for Updates using the Windows Update Tool

In some cases, compatibility issues can be resolved through updates and patches available directly from Microsoft via the Windows Update tool. This is most likely the case if you have not kept up with regular updates on your machine over time. In your settings, open up the Windows Update tool and run a scan to see if there are any required updates available for your programs or for the operating system itself. If there are updates, install them, then reboot your computer to make sure that all updates are able to be fully applied to your operating system. Attempt to open the program that caused the error after you are finished to see if this method addressed the problem fully or if an additional method needs to be used.

Method Two:  Roll Back to an Earlier Version of the Updates

Sometimes, an update can cause a compatibility issue. If you have previously been able to open the program in question without any problems, but have recently installed an update on your computer, that update may have been the source of the problem. If this is the case, roll your system back to an earlier stage of updates to see if that fixes the problem. If so, you may need to wait to reinstall the updates until Microsoft corrects the issue.

Method Three:  Run Scans on Your Registry, Antivirus Software, Drivers, and Update Troubleshooters

If there truly is a corrupted or missing file within the program that you are trying to run, you can open up several tools to scan for the file that may be causing the trouble and attempt to fix it. Run the following tools to try to fix the problems:

• Windows Registry Repair Tool (this particular tool may take some time to complete)
• Windows Update Troubleshooting Wizard
• Windows Drivers Updates
• Antivirus software or Microsoft Security Essentials

After running each of these tools, restart your computer to allow any necessary changes to be applied to your system. If the above methods do not fix error Code 0xc00000fd on your particular device or if you do not have the confidence and knowledge to implement these steps on your own, get in touch with a Windows repair professional who can help you to resolve the problem.

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.

About Potentially Unwanted Applications

Have you ever discovered an unwanted program running on your PC and wondered exactly how the heck it got there? A PUA / PUP (potentially unwanted application / potentially unwanted program) is a software program that comes bundled with freeware/shareware and you agree to install on your computer. These are programs you certainly don’t want on your computer since it doesn’t provide any useful service. Despite being regarded very dangerous, PUPs aren’t necessarily computer viruses or malware What makes a PUP different from malware is the fact that whenever you download one, you are doing it with your consent – though in most instances unwittingly and unwillingly. PUPs might not be malware but still, they’re harmful programs to your computer. At best, these unwanted applications provide hardly any benefit, and at worst, they could be quite damaging to your computer.

What do PUPs do on your computer, really?

Most Potentially Unwanted Programs will come in the form of adware, which typically aims to exhibit numerous irritating pop-up ads, banners, coupons, and bargains on websites you go to. PUPs that come as browser add-ons and toolbars are readily identifiable. They’ll track your online activities, redirect your search results to unsafe websites where spyware and adware can be downloaded, hijack your home page, and slow your internet browser down to a crawl. PUPs load up a dangerous bite if kept unchecked. They will often include things like information gathering program code which could gather and send your sensitive information back to 3rd parties. These are programs that don’t really do anything good for you; in addition to occupying space on the hard drive, they also slow down your PC, often alter settings without your authorization, the list of annoying features goes on and on.

Great tips on protecting yourself from unwanted software

• When setting up anything on your computer system, always study the fine print, like the license agreement. Don’t accept terms of use that are for bundled programs. • Only Use the “custom” or “manual” install method – and never blindly click Next, Next, Next. • Use an advert blocker/pop-up blocker; Install anti-malware products such as Safebytes Anti-malware. These software programs could establish a wall between the computer and cybercriminals. • Think twice before you decide to download any type of freeware or shareware. Just before adding a plug-in or web browser extension, think about whether it is really necessary. • Only download programs from the original providers’ websites. Avoid download portals because they use their very own download manager to pack extra programs along with the initial download.

Further Information and Manual Repair

Error code 0xd0000272 may be resolved by simply waiting until later – a few hours at most – to reattempt activation. If, however, the activation process fails, proceed with the methods suggested below or contact a Windows repair technician.

1. Method One: Verify Internet Connection to Activate Windows

Are network connectivity issues preventing your machine from activating Windows? Check for this issue by verifying whether or not you are connected. Once you’ve been able to check your connection via your Internet settings and troubleshoot your network where necessary, proceed to the Product Activation Wizard.

The Product Activation Wizard will check if you have permission or authorized access to the version of Windows you are attempting to activate. This process usually involves the use of a product key. Once you enter the 25-character code – in the correct order, of course – proceed by selecting the activation option.

If the process is successful, you will be able to complete the activation and access all the features of the Windows edition you have activated. You will also notice the absence of the error code 0xd0000272 message. In cases where this manual repair method is unable to successfully resolve the issue, however, move to the next manual repair procedure on this list.

2. Method Two: Run Windows Update Troubleshooter

Another tool available to Windows users is the Windows Update Troubleshooter. You may access the Windows Update Troubleshooter offered on Windows 8 since it does not require an internet connection and runs most of the functions required. To do so, follow the steps below.

• Step one: Swipe to the right of the screen and click Search
• Step two: Type Troubleshooting

Afterward, restart your computer then check the Product Activation Wizard to verify whether or not you can activate Windows 8 or 8.1.  If the problem persists, however, and error code 0xd0000272 reoccurs, proceed to the third manual repair method.

3. Method Three: Disable Proxy Settings

Your computer’s proxy settings may in some cases interfere with the activation process, resulting in issues like error code 0xd0000272. To fix this problem, first, disable your proxy setting then reattempt the activation process using the Product Activation Wizard.

• Step one: Press Win + C keyboard combination
• Step two: Select Settings
• Step three: Click Change PC Settings
• Step four: Select Network, then Proxy
• Step six: Switch proxy server settings to Off

Open the Product Activation Wizard once you’ve disabled the proxy settings. Complete the activation process based on the instructions provided. If you are successful, you will no longer be bothered by error code 0xd0000272 as the symptoms of the error code will not occur.
