Changed BAT File Association And Can't Get It Back
Jun 4, 2010
I went to Control panel->Default programs->Associate a file type with a program and changed the association to file .BAT to explore.exe.Now, when I click on a bat file with the mouse, the whole desktop starts shaking. I think it goes into a loop.The problem, when I go back to Controlpanel-> Default programs->Associate a file type with a program.The extension .BAT is no longer there! It is gone.And when I examine the file property of some .bat file, there is no option to change what to open it with. There is no open with... only OPEN option.There is also no way to add a new file extension in Control panel->Default programs->Associate a file type. I can't add .bat again.I did Control panel->Default programs->Set progream access and computer defaults but still the .bat file association is broken, and when I double click on it, same thing happens.Now when I right click on a .BAT file from exploer, I also do not see the EDIT option any more.

My wife recently downloaded PCHealthDoc, and somehow or other it has changed the file association for .msi install files. That's fine, I know how to reassign it, but where exactly is the Windows Installer, and what's the name of the file?

i needed to pawn my laptop for a short time and didnt want my files to be viewed by anyone while it was not in my possesion, so what i did i changed the file permissions of my c: drive so that only admin had fulll control and no one else. well now i cant access my c: drive with my admin accrt. nor will it let me change the file permissions either. also a hand full of other things will not work such as the internet explorer icon on the task bar or start menu but i can open i.e. from the recently viewd submenu from the i.e. icon on the start menu. also i can open files on my c: drive from any old shortcut icons i had left on my desktop but i cant acces them directly from explorer. so i found some work arounds but really need to get full control of my h/d.

I stupidly got the "Windows 7 Security Center" virus from an attack site that neither my browser (Firefox) nor Microsoft Security Essentials caught in time. I immediately knew what happened, but it had "hijacked" all of my programs to redirect to it (I'm guessing this lead to the broken association), so that I was unable to open my actual security program or Malwarebytes and clean up (I'm accessing the internet at work ATM).I managed to identify the invading process, shut it down, and revoked all of its permissions which seems to have it in remission as far as interrupting things. It's still there, of course, though. Now when I try to open any executable, I am met with a permission error. I am no expert at all on these matters, but it appears as though the virus changed the exe association to direct to itself, and changing the permissions only nullified the effect of accessing it.
How can I go about setting exes to open correctly so I can get rid of this thing?I haven't done much yet (I attempted a lengthy virus scan on my Linux laptop using Clam that failed miserably), so I can't rule a lot out so far. I do know that I do not seem to have the "command.com" tool that a lot of solutions for repairing the registry reference. I checked the directory and everything it doesn't seem to be there.I have a recent restore point; would that help? Could I make use of the command line in Safe Mode provided it runs?

Previously there were no issues in opening PDF files using AR. Then I could not open PDF files. I uninstalled and reinstalled AR twice I forced W7 to associate PDF files with AR I drank 7 cups of coffee while considering an alternate calling in life - perhaps an island without computers None of the above has helped. I still cannot open PDF files on this machine. I have not purchased the tickets to the computer-free island as yet s

I have a problem trying to change the program associated with a particular file extension. I was trying out different programs to find out how they could handle that particular file type, setting them as the default program and trying to open the file. But after setting the default to one program in particular, it seemed to "lock" the file type,This is true only for that particular file extention, all other extensions have this option enabled and the association can be changed. If I open the default programs control panel, and try to choose a different program to be associated with that particular extension, the entry does not change after choosing the program and clicking "OK" - it stays at the previous setting.

i have been attempting to open some .exe files but keep on getting the message 'not a vaild win32 application'. A scan with Super Anti spyware shows the following - System Broken File Association HKCR\.exe. I am assuming that something is wrong with the .exe link. I have checked the list of defaults and noticed that the .exe default was missing. I have also tried some fixes which appear to attempt to change the registry, but these have not worked. Do i need to manually change some registry content?

I received an email with an attachment showing as a pps extension, which is Power Point. Win Live Mail cannot open it. When I go to the file association panel, I have 3 extensions listed, to use Power Point Viewer (I do not have Office), but .pps is not one of the 3 listed ones. How do I add .pps to that list?

I have Microsoft Power point and in the association list, power point is designated as the software to be used for .pps files. When I get a power point downloaded attachment to my email client (.pps) and I click on it, I get the message that "it could not be opened because the helper location could not be found". I'd like to get this to work. I do know that I can save the attachment, open power point and view it but merely clikcking on it should work

At work i use 2 different PDF viewing software. One is Adobe for editing and the other is Foxit for quick viewing. They have their pros and cons and so I use them interchangeably.For some work I will use Foxit for several hours at a time and only open something in Adobe on an as needed basis using the right click "open with" context. The opposite is true, for some work I use Adobe for hours and then use Foxit as needed with "open with" context.I want a registry file or some application that will enable me to simply double click on it and KNOW that my file association for PDF is now Foxit (or Adobe depending on what batch or registry file I double click on).I see there is "HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrent Version ExplorerFileExts.pdf" which changes when I edit the file association in control panel. It does update, but I can't manually change the "UserChoice" Progid item. It changes only through file association in control panel.I realize there are some in HKEY_CLASSES_ROOT but they don't update when i update it in file association in Control panel.I don't know what to do or where else to look.It is tedious to have to go to the control panel -> file association manually.

When I put a DVD movie in my computer, right-click it and choose 'Play', I get the message: "This file does not have a program associated with it for performing this action."Until recently, Windows Media Player would play the movie. I suspect the problem has arisen since I installed RealPlayer SP. However, doing a system restore isn't practical.I can't see how to restore the relevant file association.

I'm running windows 7 on my PC. I have Adobe Master Suite CS5 and recently installed Master Suite CS6 as well. I've found that all of my files created in CS5 are now being associated with CS6... and this is a problem. I'd like the projects I create in CS5 to remain associated with CS5...

I mistakenly associated Windows Media Player with opening an email with a Power Point attachment. When I try to open the attachment, I'm told WMP can't open it. I have Power Point Viewer (which can open the attachment), installed but I can't find a way to delete the WMP association. The .eml file type (email) is being opened by Thunderbird, my email client.

Is there a way to change a file association for all users who use windows 7? I intend to roll windows 7 out within my company and prefer not to have to make this change per user if I could avoid it.

How can I create a custom command line to be used when I double click on a file with a specific extension. For example for a .jar file I'd like to have this:
javaw.exe -jar "%1" -myOpts
Can you have more than one custom command line for an extension and use the RightClick context menu to chose the one you want to use?

On a brand new laptop the user copied some word files over, and they opened on the new computer just fine. Then they copied some more .doc files and they could not open them, so (they claim) they choose word as the default file association (which is fine, except it should not have prompted for that in the first place). After that all the word document shortcuts they created on the desktop changed to a shortcut with IE's 'e' symbol - clicking them flashes up a screen that instantly goes away (ie I assume) and ie's download file dialog then opens. Further, an attempt to open ie acts the same way. Worse, running system restore does the same thing - flash, then ie files downloaded dialog - asking if I want to open one of the files listed (which are the .lnk files to the word documents on the desktop). So short of doing a full system restore, and also short of manually copying the registry files from the last restore point (which I'm not sure is even possible on a windows 7 drive) what can I do to resolve this mess?

I recently ran a memtest86 program to check my ram so I had to change my boot priority to get the program to work. Now it seems I cant change it back. I've changed it and saved it but my cdrom still wants to boot up first. I even reset the bios with no luck.

I have a problem with the entries in the start menu. Normaly I have Swedish which is what the system is set to use. But for some reason the entries in the start menu is english now!How can I change that back? Maybe it hapened when I installed and run the program "Advanced System Care" which was suposed to be a good program, but I'm not sure. I didn't help to uninstall it by the way.

I changed it was because I tried to optimize (my mistake) by reducing it. My router is set to 1365 MTU manually after a support tech from Linksys asked me to change it for a previous problem. I used the "netsh interface ipv4 set subinterface "Wireless Network connection" mtu=nnnn store=persistent" command to change it around to find what MTU Windows uses automatically. It was set at 1500 (for both LAN and WLAN). I set the WLAN to 1365 to see how it would perform, didn't see a noticable change I believe so I switched back. Now I see a slight lag when loading sites. I also compared the time against another pc that I did not tamper with (which by default was set to 1500) and that one worked normally.I fear I may have overridden Windows defaults for handling MTU since after manually setting it to 1500 (was originally 1500 when it was untouched) it lags a little. For the time being I set it to 1365 to get the performance that I normally got with default settings.
My question is if it's possible to get the original performance back with the MTU set back to what it was originally (1500)?Also I learned my lesson and won't be trying to change settings without first making sure they are completely reversible. Also I'd like to do this without using System Restore.

So i returned to my work computer after lunch and the resolution had been changed to 800x600, very odd.Now i have spent 2 hours trying to get back my resolution to the 1680x1050 that is was before but i still can not choose anything higher then 1600x1200 under Screen Resolution settings. The one with the correct ratio i can choose is 1280x960 and i'd like to bigger one back.I have updated the driver for my graphics card (ATI Radeon 3000 Graphics accoridng to Device Manager). I have updated the driver for the Monitor (HP LE2201w), but the monitor still shows up as Generic Non-PnP Monitor under Device Manager and now i am out of ideas... I really have no idea what the hell happened when i was gone.(And yes, the computer was locked so it wasn't someone else changing something)Uninstalling the driver for the Generic device does nothing, it pops back up again after installing the correct display driver, or after a restart. It's like the display driver i downloaded from HP is not being installed, no idea why.

I have a USB external hard drive that I keep all my documents etc on (had it for years)I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.
