KB5009543 or Cumulative update Jan 2022 for Windows 10 and Windows 11 is currently breaking IKEv2 VPN connections. If you are experiencing an unexpected connection failure with a vague error message like “General processing error”, please follow the below steps.
Go to Program and Features -> Installed Updates and uninstall KB5009543. Reboot the box and the VPN connection should start working normally. Optionally you may disable the Windows Update for a period of time so that the same update will not get installed once again. Please note, Microsoft releases updates to their products quite often to resolve issues those were identified. Few times these updates open new issues, like the one happened with this particular KB.
While there are no straight forward methods available to “stop” Windows updates, you can use multiple methods to disable Windows update completely, which we don’t recommend. One of them is using group policies on the local machine.
We migrated to 11G R2 (220.127.116.11) for our Oracle Applications R12 few years back, yes few years back (2017) & lived with one of the worst experiences…
Connecting Oracle Developer 10g (Forms/Reports) suite to 11G database.
I have scavenged through community articles for long time before giving up. I hardly came across a single fix for the connection time that used to hang up the Developer suite at times…
Today, I decided to find a solution for the nagging SSH connection issues from Windows 11 to our LINUX application servers and realized that we didn’t update the DNS settings for them once after we decommissioned a domain controller. Once the SSH issues were rectified and addressed, my next attempt was to find a solution for “frmcmp_batch” taking long time to start compiling modules & I landed on the below post.
As we are already on 11G R2 18.104.22.168, patching was not required. All I needed was to alter the hidden parameter “_FIX_CONTROL” as mentioned in the article.
SQL> ALTER SYSTEM SET "_FIX_CONTROL"='8560951:ON';
(Use scope=spfile to make this change permanent. This will require you to restart the database.)
I opted to go without spfile for testing & as soon as applied, the “frmcmp_batch” started compiling the modules instantly, against the usual delay that ran into many minutes other times.
Out of curiosity, I tried to connect to the database from Developer 10g & the connection was instant! within a fraction of a second.
So DNS being one of the most important elements establishing successful connections, patches and fixes also play crucial role in providing stable connections. Were you stuck with the same issue? give the solution a try and let us know whether it helped you also.
We decided to retire one of our Windows 2008 (32-Bit) servers, hosting multiple classic ASP intranet applications. Our immediate choice was another VM, that runs Windows 2008 R2, 64-Bit OS with IIS 7.5.x as intermediatory until we setup a brand new VM running Windows 2019 & soon realized that we were in tight spot as any attempt to access intranet application(s) from the new host started prompting for authorization for applications that were using “Windows Authentication”. All our application servers are domain members, so are our clients.
We did an apple to apple comparison between servers/IIS setup, visited dozens of threads & yet were unable to fix the “problem”, that was the site/application asking for authentication for a user who is already authenticated by the Active Directory!
After referring third link, had the answer to our problem. Actually, if a client wants to negotiate authentication using “Windows Authentication” through a website by passing currently logged in user credentials, that website should be in Local Intranet zone, which was, for us controlled using a Group policy. This is strictly to make sure that user details are not shared with Internet zones, as a security measure.
Once the new site name was added to the zone list and group policies updated, we were able to access the intranet applications without further issues.
Today I re-installed Windows 11 on my computer. Actually I had upgraded from Windows 10 to Windows 11 on October 5th, 2021 the same day Microsoft released the half baked OS to public & all of a sudden I realized that, it was a blunder. So, after regretting over a month, I decided to re-install the OS and started installing all my development tools & you know what, I had to refer my Windows 7 post for installing Oracle Developer Suite 10g on my Windows 11!
Much of the post below is from the earliest post that I had for Windows 7, explaining hacks to install Oracle Database 10g and the Suite. Oracle Database 10g is not anymore significant, hence I removed the database part and posting the rest for few unfortunate Oracle developers out there. Well, 10g is used by many business application as on date & if you are looking for a method to install Oracle Database 10g on Windows 11, Please search the blog for Database 10g and you will land on multiple posts explaining to how (Refer Windows 10 articles)
Step 1 Setup Virtual Memory
If your computer has 8GB or more physical memory, all you need is to setup the Virtual Memory for the name sake. Limit the virtual memory to 2048 (2G) or max 4096 (4G). Please use the below images only for reference purposes. After changing the Virtual Memory, You will be asked to restart the computer and please restart.
Step 2 Setting up the Developer Suite
Depending upon the media that you are using for the installation, Oracle Developer 10g has 2 discs & I have copied the content from both disks inside a folder on my computer. (As you could see in the image above)
Open the Disk 1 folder and locate “Setup.exe’, right click and change the compatibility to Windows XP Service Pack 2 or 3 (doesn’t make any difference)
That’s all. Right click and run “setup.exe” as Administrator. If you have a JAVA installation already on the computer, you might receive a warning message for missing entry point, that you can safely ignore.
Follow the same compatibility setting for patch sets, if you have any. Let me know about your experience through comments.
If you have already installed Oracle 19c following instructions available here, installing Oracle database 21c is not much different. Basically 21c is “Innovation Release” & 19c is going to be the long supported version as on date. It plainly means, there is no need to hurry to upgrade your 19c to 21c as next release will be the next long supported version.
Let us see how to install Oracle 21c on Windows (Installed on Windows 10 21H1) & the instructions are same for Windows 11 also.
Extract the .zip and change the root folder to something like “Oracle12c” (or a name that prefer. Please avoid using spaces with the folder name, example: “Oracle 21c”)
I used a virtual machine with single drive, hence the zip file was extracted and I renamed the extracted folder root to “Oracle21c”
Once the folder is renamed to your choice, open the folder and execute the “setup.exe” as administrator. Please note, you must start the setup as administrator, regardless whether your Windows user account has administrator privileges on the system.
This will kick start the installation process and depending upon the resources available it could take minutes before the installation GUI appears for you.
Choose “Server class” regardless whether you are installing it on a Server OS or client OS. It’s all about managing the resources.
Now, this is a very interesting perspective. “The software directory is the Oracle Database home directory” & the path that you will mention in the edit box is going to be the Oracle base. I hope, now you understood why renaming the media extracted folder to a very meaningful name is important. As usual Oracle suggests you the defaults, however I recommend you to follow a pattern that you can feel comfortable with.
As you could see, the default installation sets up one pdb. You may rename the default PDB at this level.
Here I left everything to defaults as my intentions were pretty limited to installation. Unless you have a reason to set up Automatic Memory management, go ahead with the well trusted manual management, that gives you granular level control on how the memory is utilized by the database.
You can change the database character set to another from the “Choose from the following list of character sets” (Specifically for Arabic and other left to right languages)
You may choose a different location for the database data files. Just make sure that the current user has full access to the path.
Use the same password for a TEST installation & follow the Oracle recommendations for PRODUCTION environments. Please note, it’s better to use the complex passwords with expiry disabled for the default profile.
That’s all folks. It’s not like the earlier times when one had to hack the installation files to install Oracle database on newer Windows OS. Starting from 11g, Oracle database gets installed on Windows 7 and later OS without complaining as long as the OS is fully patched with updates and .NET components.
I started blogging once after upgrading to Windows 7 & posted mostly about the ridiculous bugs Microsoft exported with that OS. Gradually Windows 7 got matured (hardly ever fixing the yellow triangle network icon issue) & my entire attention switched to what I do for salaries, Oracle development & later much of my posts were about the stack.
Now Microsoft has released another half cooked OS, Windows 11. From a layman perspectives I cannot understand how someone could make such decisions that affect the established stability and ease of use of an OS that creates huge disappointments for general userbase!
Other than cosmetic changes and revamped settings area, I cannot defer Windows 11 from Windows 10, plus the disappointment of losing the start menu that I was getting used to after loads of patience and efforts. Among many of such grievances, connecting to VPN at work is so ridiculous, requiring 4 mouse clicks! So I decided to go with a cmd/powershell script this time to avoid those 4 mouse clicks.
After weighing the possibilities of extending , I decided to go with PowerShell (Version 5)
So let us check how it works. Copy the following in to a text file
rasdial.exe "Your VPN Name"
Save the file as “Dial VPN.ps1” or any other name you prefer with extension “.ps1”.
Make sure you wrap the VPN name using double quotes. “rasdial.exe” is not a powershell cmdlet, an old Windows OS friendly dialer. This executable is generally found in the Windows\System32 folder and there is no need to specify the path, unless you modified the PATH environment variable. Now create a new shortcut on the desktop and type/copy the following (Please adjust the file path as per your setup) as command for the shortcut
powershell.exe -File "C:\scripts\Dial-VPN.ps1"
Usually I keep all my scripts in a folder named “Scripts” on the C: drive. Hence the -File parameter clearly mentions the script’s path.
That’s all, you can double click and open the pre-configured VPN connection without going through the 4 click hassles on Windows 11 (or multiple clicks on other Windows OS versions)
Now, let us look at a fancier version of the above. What if you want to connect if not connected and disconnect if already connected? Please note, this script could be extended beyond this level depending upon specific requirements. I have started with the skeleton and will be happy to receive better scripts from you.
Please note, I am a beginner with PowerShell(Also) and always will be. As usual, I have provided the links to original codes & possible other links those helped me to device the above.
The above can, dial your VPN connection, warn you before you disconnect etcetera. For my ease, I prefer to use the extended version of the script as I keep on switching the connections. You may able to extend the script once again by accepting the VPN connection name, so that you can use the same script for dialing different VPN connections (if you have many)
Have suggestions? please pass them to me through the comments section.
I would like reiterate something Anoop has mentioned in his article. If you are using Microsoft SCCM or Windows Update Services (WU), then you must enable the local group policy as he has mentioned clearly in his post.
The image attached by Anoop could be bit confusing for the local group policy setup, hence I am uploading one with better visibility. The path is “Computer Configuration->Administrative Templates->System” & you need to open “Specify settings for optional component installation and component repair”
No need to reboot the computer for installing RSAT components. Follow Anoop’s thread and be a happy Administrator!
There are situations, especially while using Windows 10 gen OS (Windows 2016+ Servers included) a user might not able to type inside
Windows Search Textbox
WIFI Password Textbox
For some strange reasons, typing inside these text boxes are supported by “CTF Loader”(C:\Windows\System32\ctfmon.exe)” & that is loaded into computer’s memory normally after a restart/reboot.
This is facilitated by one of the Windows Tasks & certain attempts like using KMSPICO tool to activate Microsoft software, which is ILLEGAL and many times breaks this Task.
So, how do we fix it? There are two different approaches
Rebuild the Task
We’ll see both methods in detail now.
1# Rebuild the Task
If the KMSpico tool or other reason corrupts the Task, you will not find any entries in the folder “TextServicesFramework”
when an intact task should look like below
So how do we recreate this task, that is a custom handler?
Browse to “C:\WINDOWS\System32\Tasks\Microsoft\Windows\TextServicesFramework” & check whether you can find a file “MsCtfMonitor” inside the folder. If you cannot find the file in this folder, copy the file from another Windows machine that has the same version.
Copy the file to desktop and add the extension “.xml” to it.
Opening the file with notepad or another text editor should look like the following:
Go back to Task Scheduler and right click on “TextServiceFramework” and select “Import Task”
Point to the xml file that you have created in the desktop & apply. This should create a new task under the folder “TextServiceFramework”
Restart and confirm you can type in the search box and WIFI password text boxes. Alternatively you can use the Task Manager to check whether “CTF Loader” has been loaded.
Remember, registry entries might get removed through updates/new versions. However, as a temporary measure you can use the following hack to address the keyboard issues.
Make a full backup for the Registry. You must know, tampering registry could force you to a fresh installation of the OS!
Once a full backup for the Registry is made, browse to “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run”
Create a new string key and call it anything that you want. Example
I have called the string key as “CTFLoader” and for the Value make sure to enter “ctfmon”=”CTFMON.EXE”
Reboot the computer and check whether the typing issues resolved. Alternatively use Task Manager to check whether CTF Loader has been loaded.
Although both fix the typing issues, the right way is to recreate the missing Task. Choose wisely & don’t pirate! We know many interesting software are pricely and many of us cannot afford them. There are free alternatives for maximum pirated software like
And many more software that you need for Office/School/Home works! Piracy not only breaks the businesses that develop them, helps cyber criminals to unleash attacks like Ransomware through serial number generators and patches.
There are times when you come across the error “Windows cannot connect to the printer” (error 0x000003e3) while trying to connect to a “shared“ printer that is connected to another Windows 10 computer.
Quite possible that the drivers installed on the source machine is either not compatible with the client/target machine or not getting copied to the target machine. Now, install the correct version of printer driver to the target machine and try to connect again. There could be few other items you must check and insure for a successful connection.
Make sure both the computers network property shows the connection as either domain or private.
Make sure you have File & Printer sharing enabled for the network
Much of the times I use latest Oracle technologies for learning & they hardly make to any of the PRODUCTION environments those I support at work. Recently I wanted to see how to patch Oracle 19c installation on Windows and to be frank, it was buttery smooth.
Let us quickly see how to apply a patch to a Windows installation of Oracle 19c database.
Shutdown all instances & Windows services for Oracle. Make sure you have taken adequate number of backups for the database(s).
Check you computer’s PATH variable. Insure you have %ORACLE_HOME%\perl\bin, in my case “D:\Oracle\19c\perl\bin” as the first entry for PERL.
This is how the PATH information before I make the above changes to it.
Once the patching done, you can rollback the PATH variable according to your requirements.
Visit Oracle support and download the patch, the latest patch for Oracle Database 19c is “32409154”. Patch is only available to customers with a valid support contract.
Extract the archive.
I’ve extracted the archive within the Download folder and the path is
