Fixing “The .NET Framework 4.7 is not supported on this operating system” Error in Windows 10

Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!

How to speed up Windows 11?

1. Disable startup programs

There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.

To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.

This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.

2. Expand your memory and storage

If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.

Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.

3. Clean up disk space

If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now. 

Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).

A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice. 

For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.

Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.

4. Install pending updates

This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.

5. Disable visual effects

As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.

To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.

Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.

6. Get rid of bloatware

Bloatware is one of the biggest culprits of slow computer speed. 

Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.

To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’. 

Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.

Summary

These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!

intel's first gaming card that will hit the market soon has been shown in its innovation event, the Intel Arc A770. In its core ticks ACM-G10, coming with 32 Xe-cores and all the way up to 16GB of GDDR6 memory (the basic entry-level version will have 8GB of GDDR6). The card will support ray tracing and supersampling with Intel's XeSS.

This is Intel's first gaming desktop GPU and after testing with some YouTube channels it turned out that the card itself sits somewhere between nVIDIA RTX 3060 Ti and an RTX 3070 so it will still be low in performance compared with the new RTX 4090 or AMD's new RDNA3 upcoming lineup. But as stated this is Intel's first gaming graphics card and having this kind of performance is no small feat for the first-time product.

One thing that is really great tho and that is going for Arc A770 GPU is its price! The Limited Edition card will cost $329 which is at this moment most cheapest GPU currently on the market in that performance range. nVIDIA is between $500 and $700 for comparison and if Intel can hold on to its performance with almost half the price card could be a great hit among gamers. GPU itself will launch on October 12th.

If you are using a Windows 10 PC that has different processors clubbed together, chances are you might encounter an error saying, “MULTIPROCESSOR CONFIGURATION NOT SUPPORTED” during a Windows upgrade or software installation. This error is actually caused by a bug check with a value of 0x0000003E. This error also indicates that the processors in your computer are asymmetric in relation to one another. So if you want to upgrade you need to have all the processors of the same type and level. But worry not for this guide will help you in fixing this error. The MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED error can occur in several cases such as during an installation of Windows 10, or when the driver is loaded, or when Windows Start or Shutdown and the chances of you getting a blue screen is very much high. To fix this error, refer to the options given below and make sure to follow them carefully.

Option 1 – Try to disable the Hyper-Threading in your BIOS

Hyper-Threading in the BIOS lets a processor (multi-threaded) run various tasks in a simultaneous manner. To disable this, here’s what you have to do:

• Restart your computer and boot into it right after. To do that, tap the F2 key.
• Once you’re in the BIOS, locate the Hyper-Threading option which should be located under the Performance section along with other options like Multi-core support, Rapid Start technology, and many more.
• Disable Hyper-Threading and then make sure to save the changes and exit BIOS.

Note: Although Hyper-Threading is only used when necessary, there are some OEMS that don’t have the option to disable it and if that’s the case, you need to try other options given below.

Option 2 – Try to disable the Virtualization in the BIOS

Virtualization in the BIOS allows users to run a single physical resource such as the server or storage device to appear that it is running as multiple logical resources. It is also properly termed as “HYPER-V”.  To disable it, refer to these steps:

• Boot into the BIOS as you did earlier.
• Then look for the Security options.
• After that, from Security options, look for Virtualization Technology or VTX among the options given.
• Then turn it off and restart your computer.

Note: Although Windows 10 offers features such as the Device Security for Core Isolation and Memory Integrity, if you turn them off at the software level, it will not help at all. If you’re able to resolve the error, you can do some further research and see what software or hardware you can use to further help you.

Option 3 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the MULTIPROCESSOR CONFIGURATION NOT SUPPORTED error. You can just go to the OEM’s website as they offer utility software that can download BIOS firmware and update it without any problem. BIOS updates usually offer enhancements and fixes to some issues like this one.

Experiencing issues while using Remote Desktop connections is not uncommon. One of the issues that users encountered recently while trying to connect to their Remote Desktop network is the error saying, “Your credentials did not work, The login attempt failed”. If you are one of these users, then you’ve come to the right place as this post will walk you through fixing the problem. When facing this kind of problem, the first thing you can try before you do some troubleshooting steps is to verify the credentials. But if you are certain that you’ve entered the correct credentials just like what other users reported, then it’s completely a different matter. Based on the reports, this error is common on newly installed versions of Windows 10 or after reinstalling the operating system which could mean that the problem might be due to the Windows security policies or the username might have been recently modified. The latter case is a possibility especially if you’ve reinstalled Windows 10 and had entered a new username. In such a case, you will really have a difficult time connecting to your Remote Desktop connection since its credentials do not really automatically change. If you’ve verified that your credentials are correct, then now’s the time you troubleshoot the problem with the help of the potential fixes provided below. Just make sure that you follow each one of them in sequence.

Option 1 –Try to run the Network Adapter troubleshooter

To run the Network Troubleshooter, refer to these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
• Restart your computer.

Option 2 – Try to change the network profile from public to private

According to some reports, this error occurs on systems where the network profile was set to public. Thus, you need to change the network profile to private to resolve the problem. How? Refer to these steps:

• Go to Start and from there click on Settings > Network & Internet > Status.
• Next, click on the “Change connection properties” option.
• After that, set the radio button of Network Profile from Public to Private.
• Wait for a couple of seconds until the system is done applying the changes you’ve made and then see if you can now connect to the Remote Desktop connection.

Option 3 – Try changing the account username

As mentioned, one of the possible causes for this error is the reinstallation of the operating system. You might have changed the username for the system but it does not really change the username of the Remote Desktop connection as well. Thus, you have to change the username back to what it was before you’ve reinstalled Windows 10.

Option 4 – Try modifying the Windows Security Policy

You can also try to edit the Windows Security Policy as it could help in resolving the error. This Windows Security Policy, when enabled, will not allow non-admin users to log on to the Remote Desktop connection. So if you want to allow non-admin users to use the Remote Desktop connection, then you need to modify this policy. Note that you can only do that if you are the admin of the system yourself.

• Tap the Win + R keys to open the Run utility.
• Then type “secpol.msc” in the field and tap Enter or click OK to open the Local Security Policy.
• After opening the Local Security Policy window, select Local Policies > User Rights Agreement located on the left pane.
• Next, double click on “Allow log on through Remote Desktop Services” located in the right pane.
• And in the next window that appears, select Add user or group.
• After that, type in the username of the intended non-admin user under the “Enter the object names to select” column.
• Once done, click on the Check Names button to fix the username and then click OK to save the changes made.
• Restart your computer.

Option 5 – Use the Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer Configuration > Administrative Templates > System > Credentials Delegation.
• Double click on the “Allow delegating default credentials with NTLM-only server authentication” policy setting located on the right pane to edit it.
• After that, shift its radio button to Enabled and click on Show.
• Then type “TERMSRV/*” in the Value box and click OK.
• Now repeat the same for the following policy settings:
  • “Allow delegating default credentials”
  • “Allow delegating saved credentials”
  • “Allow delegating saved credentials with NTLM-only server authentication”

• Once you’re done, restart your computer and see if the problem is fixed.
