Windows 11 Launch Internet Explorer
Raiquen Courcelle
I would like my app to open urls in Internet Explorer only. The end users in my organization use google chrome, however, the website I need to link to only run in internet explorer. The URLs to the site are stored in a table, and when viewing and filtering data, I would like for the end user to just click the link and pull up the website in IE, even if they are using the dashboard application in google chrome.
Is it possible to write a launch statement that forces the URL to open in IE? Or maybe there is another way of doing it.
Alternatively, if your organisation supports it, you could look at implementing a custom protocol handler to force the use of IE over the default browser eg iebrowse://google.com. I'm actually not even sure how well this is supported anymore, however, this Microsoft document may be of use:
Like many a techie, I've read the recent flurry of advisories on a new criticalvulnerability in the Internet Explorer legacy scripting engine (jscript.dll), and how it's beingactively exploited. On its own, this can happen, right. But what annoyed me was the portend of gloomand doom around the Web. Mostly panic, with very little focus on trying to analyze this problem, andsee if it can be mitigated in an elegant way.
In fact, Microsoft has listed a workaround - you can deny access to the affected library. But thisalso causes side effects. You may see problems with printing, access to the group policy editor, and afew other issues. So I sat down and thought, is there a way to reduce the impact of thevulnerability, without actually making the system go all wonky?
The vulnerability exists in the (Internet Explorer) scripting engine. This means that any programthat calls on this engine could potentially trigger the memory corruption, and potentially lead to anarbitrary execution of code. Prevalently, this means Internet Explorer, possibly Microsoft Office, andmaybe some odd legacy applications, which are not likely to be found in the typical homeenvironment.
The solution is to not run Internet Explorer - and avoid opening strange files or links in otherprograms. Now, this is always true, regardless. The problem is, what if you "accidentally" openInternet Explorer against a page that could trigger this vulnerability?
Windows has had the option to disallow certain applications for a long time. This can be implementedthrough the registry or the group policy editor (for pro version users), and will prevent listedprograms from running. Specifically, launch gpedit.msc, go to User Configuration > System, and thenopen the policy that reads: Don't run specified Windows applications.
Now, this works as advertised - but only if you use Windows Explorer or the Start menu to launch theprogram. It will not block access by other means, nor does it stop applications from using thejscript.dll library. Don't worry, we will get there. I am progressing slowly, linearly.
We have talked about this super-useful and powerful feature in the GWX context. You can use it to change how any whichprogram on your system behaves. Basically, we will use the Debugger functionality, and thus change theexecution of iexplore.exe from its default behavior to running an empty cmd shell. Basically, a dummyrun that does nothing and invokes no Javascript libraries.
What this will do is let you "run" Internet Explorer, but the entire run will just be a spawning ofthe command prompt shell that simply exits. This means that no matter how you invoke Internet Explorer,it will not really run, reducing the risk of the jscript.dll library being loaded into memory.
Now, please note, this only affects Internet Explorer, and does not prevent other programs fromusing the library, like say Microsoft Word showing a document with a malformed embedded object thatreferences the jscript.dll functions. But it reduces the risk of the library being used, especially bya network-capable program like Internet Explorer. Other tools on your system may still require thislibrary, but if they don't necessarily connect to external network resources, then the risks arereduced.
Lastly, if you use anti-malware software, some may see this as a potential IFEO Hijack. Be aware ofthis fact, and then move on, and perhaps even embrace a smarter way of doing computer security. Butthat's a topic for another time.
Now, my work above does not fix the problem. It works around it by reducing the chance of InternetExplorer running. The proper fix is to update the library. Technically, you could "just" copy the newpatched version over the old one, and you're done. But the Windows Update mechanism is a bit morecomplex.
So the mitigation is to remove the executable permission from the library. You can do it on thecommand line, as the advisory says, or you can do it using Windows Explorer. The reason for the commandline is to take ownership of the (system) library, to be able to change its security settings.Alternatively, you can manipulate the permissions by opening cmd (or explorer) through ExecTI, autility that lets you run programs with the highest privileges, as I've shown you in my list of must-have Windows admin utilities.
What you want to do is remove the Read & execute checkbox mark for all of the listed groups orusers. But then, the side effects! For example, the aforementioned Group Policy editor will not launchcorrectly if execute is denied for Administrators. This also emphasizes the importance of running as standard user, as you could have no execute for Jscript for Users, andyou would still be able to use Internet Explorer then, without any effect on system functionality.
But then, since this is all there is to it, you can disable Read & execute, and toggle it whenyou need it, until you can apply the official patch - provided you actually want to apply it. In somescenarios, you might not want to, or be able to, and you might even have to use Internet Explorer. Butthis is not likely in the home setup. And I'm not talking enterprise security here. So lower yourpitchforks. Finally, you can do the same thing for Internet Explorer - remove the executepermission.
Then, if you do need to use Internet Explorer, you can disable Active Scripting under InternetOptions. This is old news really, so I'm not going to focus too much on this here. A more practicalthing is to avoid accidentally executing Javascript files stored on your local disk, through theMicrosoft Based Script Host. This is the default, even on Windows 10. But in reality, there are veryfew reasons why you'd need to run Javascript files locally, outside the context of your browser.
What you want to do is create a dummy Javascript file, something like file.js. Right click > Openwith, and then select a text editor of some kind (under More apps). This means that even if you dodouble-click on a locally stored Javascript file, it will open as a text file.
Don't let panic be your compass. Some security problems are serious and require scrutiny. But othersare not necessarily as dreadful as they may seem, based on the Internet chatter. In this case, yes,this is not a good thing. On the other hand, not running Internet Explorer pretty much solves it. Also,don't be an n00b and randomly execute files left and right, and you should be fine.
In this article, I tried to give you a somewhat calmer overview of what gives, and the options youhave. Most importantly, you can use the fabulous magic of IFEO to prevent Internet Explorer fromrunning, no questions asked. This way, you reduce the risk of nonsense, be it an old game launcher thathard-codes to iexplore.exe for messages or announcements, or your own twitchy fingers. You can alsodisable the execute permissions for the library, and if your system is set up with a standard user, youmight not even need to compromise on reduced functionality due to the disabled library. There we go.Enjoy your Webz.
I work on Internet Explorer. first i launch the internet explorer with URL . then open two pages one is URL web page and another is blank page. i want to open only URL web page. but i facing this issue. please help.
Not sure how the public channels have been affected, but IE is end of life, so those actions may be in jeopardy of leaving soon. It may be a good time to move that operation to Edge, Chrome or Firefox for compatibility with PAD going forward. That being said...
Actually i using same attach to running internet explorer but by using this, first open URL page is important. thats why i am using Launch new internet explorer . but using this opening two web page. please find below attached screenshot. please help me to resolve issue.
When PAD opens multiple pages on the Launch New actions, that would imply that PAD wasn't successful the first time, so it tried again and was successful. There may be some settings blocking PAD from getting that initial response from Internet Explorer. Also IE is EoL and our strong recommendation would be to switch to a modern browser if possible.
