Android apps inside Windows 11

Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

The New and upcoming HAF 700 Evo from Coller master is a beast of a case, but so is its price. The case itself is still not released but as sources say it will be soon, well at least we hope so. The price will be around $500 which is a little on the expensive side of things but the features it is bringing are very impressive.

HAF 700 EVO Size and its advantages

HAF stands for High Airflow and with this case, you are going to get it but first let us talk about other characteristics of the case. Firstly case is ATX full tower, pretty big going 24.64 x 11.45. x 26.22 inches in size but like all full tower cases it can hold all motherboard types including Mini-ITX, Micro-ATX, ATX, E-ATX. The large case size also lets you place a pretty big GPU, going to 19.29 inches (490 mm) in its length covering currently all available Graphic cards on market.

Being a very big computer case is not just placing motherboard and big GPU, there are other great advantages of it, firstly that you can go wild with your CPU cooler, going all the way to 6.5 inches in cooler height will satisfy all users and having 12x 2.5 or 3.5-inch internal bays will. And if even that is not enough you have 8 expansion slots available.

Inside HAF 700 EVO

Inside the casing you will also find 2 front fans with 200mm diameter, 2 rear fans sized 120mm, and 1 bottom fan of 120mm. You can also manually mount standard 120mm fans on top of the case for maximum airflow.

Front panel and outsides

The front side is filled with 4x USB 3.2 Gen 1 Type-A (5 Gbps), 1X USB Type-C (up to 10Gbps), 3.5mm both headphone and audio jack along with a reset switch. Also, the circle in the very front is a hi-resolution LCD customizable display, you know, just to add more flavor and personal touch to the case. Fron is also filled with glass panels emitting RGB light.

Of course, you must also have a Tempered Glass Side Panel and well weight of 53.57 pounds (24.3 kg), yup you read that correctly, beside its hefty price tag this cooler master beast also is pretty heavy. Granted all of the weight comes from the glass front panel it is still a little hard on moving and taking out of the box.

This is also the case where you will not need a single screwdriver, everything is made to be assembled with your hands alone pushing easy assembly into the front row.

Conclusion

So in the end what are my thoughts about this expensive and heavy PC case? Would I recommend it? The answer to that question could depend really on your budget, let us be really honest here if you can afford it, YES, wholeheartedly I would recommend the case, it is great, it feels great, it looks great and the airflow is amazing. However, if you are tight on a budget, there are other great cases with excellent airflow and you might want to skip this one.

If your VPN software blocks and disconnects the Internet or Wi-Fi connection as soon as it is connected, read on as this post will give you fixes to resolve the problem. This kind of issue is odd but not unheard of. Many users use VPN for privacy and security but if it causes internet connection problems, you have to pin down the root cause of the problem and fix it in order to continue browsing the internet with privacy and security. Here are some suggestions you need to check out to resolve the issue between your VPN software and network.

Option 1 – Try installing the latest version of the TAP adapter

Since all VPN software uses a TAP adapter which is mostly from OpenVPN, you might want to download and install the TAP adapter driver to resolve the problem.

Option 2 – Run the Network Adapter Troubleshooter

• 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.

Option 3 – Configure the client computer to use the default gateway

This kind of connection problem can occur when you configure the VPN connection as the default gateway on the remote network. In such a case, the VPN settings override the default gateway settings (TCP/IP settings). Thus, you have to configure the client computers in order to use the default gateway setting on your local network for internet traffic as well as a static route on the remote network for VPN-based traffic.

Option 4 – Try to use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could help you resolve the internet connection problem caused by your VPN. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Try checking the settings of your VPN software

If your VPN software has a built-in “kill switch” it prevents any internet usage every time there is a problem in connecting with the VPN server which explains why your internet connection is disconnected when your VPN software is connected. In addition, you could also try to change your VPN software’s protocol since all VPNs support multiple protocols. It could be that the protocol your VPN uses is blocked so try changing to another protocol and see if it fixes the problem.

Option 6 – Update the Network Adapter drivers

You might also want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
