When downloading files for patching or drivers you may need to verify the file is complete. This can be done by verifying the MD5 checksum from the steps below on your PC or Mac workstation.
Solution:
Windows
Open the Windows command line. Press Windows + R, type cmd and press Enter. Alternative: You can also open command prompt or Windows PowerShell from the Start menu, of course.
Go to the folder that contains the file whose MD5 checksum you want to check and verify.
Command: Type cd followed by the path to the folder. Tip: You can drag and drop a folder from Windows Explorer to insert the path.
Type the command below
certutil -hashfile <file> MD5
Replace <file> with the filename.
Tip: You can use the Tab key to have Windows complete the file name. Example to get the MD5 hash for the file Example.txt:
certutil -hashfile Example.txt MD5
Press Enter. Compare the resulting checksum to what you expect:
Mac
Open Terminal.
Navigate to the folder that contains the file whose MD5 checksum you want to verify.
You can open Terminal right at a folder from Finder.
Type md5 followed by the filename:
md5 <file>
Dragging and dropping: You can also type md5, then drag and drop the file you want to check onto the Terminal window.
It can be frustrating to see that the PC you spent a lot of money on only uses half the RAM you put on it. There are numerous factors that can cause this issue and, fortunately, they do have fixes.
If you have been experiencing the issue that only half of your RAM is usable, the first fix below might do it for you already.
So, if you’re asking why only half of your RAM is usable, these are the most common causes and the fixes to unleash your RAM to full capacity.
Only Half of RAM is Usable: Causes & Fixes
Windows installation
We’ll start by trying to determine why only half of your RAM is usable on Windows 10.
If you remember how you installed your Windows operating system on your PC, you should know if you have installed the 64-bit or the 32-bit version. To double-check, you can open the systems information application and check your PC’s specifications.
On your Window search bar, type systems information and open it. Once you open it, go to the systems summary tab and you will be able to see a ton of information about your computer. Look for “System Type” and you will see if you are currently running a 32-bit or a 64-bit Windows.
Another way to check is by opening “Dxdiag” from your computer. You can search it on the Windows tab or run the keyword on the Command Prompt. When you open Dxdiag, look for your operating system and it should say something like “Windows 10 Pro 64-bit”.
The reason you are checking this is that if you are running a 32-bit system, your computer can only access 4GB of RAM. The difference between a 32-bit and 64-bit system is immense.
At this point, if you see yourself running a 32-bit system, you have identified the problem right away and the only way to fix it is by reinstalling your operating system (Windows) to a 64-bit installation.
Memory Limitation
Another possible issue would be your computer having a set limitation for the usable memory available on your computer. It has to be manually applied but it does happen that this might be the cause of the problem.
To fix the issue, go to your search bar and open “run”. Type “msconfig” to bring up the system’s configuration settings.
You can also just search system configuration on the Windows search bar and open the application. On system configuration, go to the boot tab and click advanced options.
You will see “Maximum memory” with a check box. Make sure to untick the check box so that your PC can freely use all the memory your PC has at the moment.
Check if your RAM is connected properly
Before you blame your PC for only using half the RAM available, check your RAM physically if it is connected properly on your motherboard’s DIMM slots. Use a trial-and-error if you see that it is properly connected.
This is to check if the RAM is faulty or not. Attach one RAM at a time and boot the PC up.
Open the task manager and check your memory usage. Just open the performance tab and check the memory capacity and usage if it aligns with the RAM you just connected to your PC. Do this for each of your RAM sticks by turning off the computer and reconnecting the other RAM stick after booting.
Generally, you might want to do this option last since you might be able to fix your memory with the other methods especially if you are unfamiliar with building PCs.
Registry Editor
Export your Registry Editor first so you can restore it to the original settings if you do something wrong. This is important because if you make mistakes in deleting or editing other files here, things can go wrong when you use your PC.
Once you open the Registry Editor, look to the left table and find the HKEY_LOCAL_MACHINE folder. Under that, find Systems and then CurrentControlSet (1 word). Find Control under the CurrentControlSet and then Session Manager. Under Session Manager, find the Memory Management folder. This should be the last folder out of this long list of steps.
To sum it up – HKEY_LOCAL_MACHINE > Systems > CurrentControlSet > Control > Session Manager > Memory Management
Inside the Memory Management folder, switch to the right table and find “ClearPageFileAtShutdown”. Once you open it, you will see the value name, value data, and base. Just change the value data from 0 to 1. If it was already set to 1, it is already fine.
Conclusion
It is best to go in order when you follow these steps in fixing your usable RAM.
It can be risky to break open your PC or tweaking the registry. If you have no choice, it is better to take precautions on how to carefully open your PC to check your RAM because all the parts are fragile.
If you absolutely have no idea how to open your PC, it is best to just bring it to a computer store and have it checked for a fee. Most likely, they will be fixing everything for you.
If you have a broken RAM, you can check how many RAM slots you have and also see how to check your RAM type for your current PC build. Both can be done through the task manager and researching your motherboard’s specifications. This is for adding new RAM sticks for your PC build if you really need more memory.
This article will help you to fix Windows Update error code 0x800f0922 received after failure of update installation in Windows 10.
It is often recommended that you install latest available updates in your Windows 10. However, sometimes you may not be able to finish installing updates due to an error code. 0x800f0922 is one of such error code which you may receive with Windows Updates. In this article, we will see why this error code appears and how you can fix Windows Update error code 0x800f0922.
You can see in the above screenshot, the error code 0x800f0922 appeared while installation of a cumulative update is failed. You can receive this error code on any of the Windows edition. In Windows, technically the error code 0x800f0922 interpreted as CBS_E_INSTALLERS_FAILED. When you’re getting this, it means processing advanced installers and generic commands failed. This error code is not specific to Windows Update, as it a general error code. It can be often spotted while installing .NET Framework.
The error code 0x800f0922 can appear due to following reason. PerfCounterInstaller, the installer Windows Update is using, may have its counter database corrupted. You can easily fix it using Command Prompt.
Here’s how to fix Windows Update error code 0x800f0922.
Fix: Windows Update Error Code 0x800f0922
FIX 1 – Using Command Prompt
1. Right click Start Button or press W8K + X keys and select Command Prompt (Admin) to open Command Prompt as administrator.
2. In the Command Prompt window, type following command and press Enter key. It will simply fix the counter database.
lodctr /R
If the command execution is successful, you would receive ‘Info: Successfully rebuilt performance counter setting from system backup store’ message.
3. Next, execute the following command to make the counter consistent and resync them with Windows Management Instrumentation (WMI).
winmgmt.exe /RESYNCPERF
Once these command executed successfully, you can try installing the updates again. You’ll no longer receive the error code 0x800f0922 now.
FIX 2 – Using DISM Restore Command
If FIX 1 doesn’t solve this issue for you, try running DISM restore command.
In the Command Prompt window, you can execute following command:
