dirkvdp 0 Posted February 22, 2014 Report Share Posted February 22, 2014 I downloaded Emsisoft Emergency Kit yesterday, and tried it out on my computer.Looks like a fine and extremely useful program to carry on my USB stick, but I've got one remark:When I try out a "portable" program (which obviously comes without an uninstaller) I monitor the first run with Ashampoo Uninstaller. I found out that the changes to the Windows registry (Windows XP SP3) where within acceptable limits, but when I tried to undo the changes with Ashampoo Uninstaller, I discovered that the following registry entries were left behind after running the uninstaller routine: Registry changes.txt. They also appear to be unremovable manually in regedit. I'm fairly sure that these references to the "legacy driver" cleanhlp32.sys are harmless, but as your program was obviously able to enter them into the registry, it appears to me that there must also be a way to remove them. Just out of interest: is there a way to remove these entries? (I'm not unfamiliar with the Windows registry.)Merely my personal opinion - but I feel that a portable program ought not to leave anything behind on the PC it's being used on (which may be somebody else's...) Tks for you help. -- Link to post Share on other sites
Masood 1 Posted February 22, 2014 Report Share Posted February 22, 2014 Go to safe mode and see if you can remove them sometimes you can remove registery keys cause a process may have the key open. Link to post Share on other sites
GT500 854 Posted February 22, 2014 Report Share Posted February 22, 2014 You're not supposed to remove those entries. Windows expects that LEGACY registry keys will never be deleted. Link to post Share on other sites
dirkvdp 0 Posted February 22, 2014 Author Report Share Posted February 22, 2014 Maybe I could remove them in safe mode, but it might not be awise thing to do, considering Mr Wilkinson's reply.. So be it! But I still think that true "portability" should imply leaving no registry traces behind (except for the normal MRU keys and the like). Thanks both ... and am still interested in other peoples opinion on this item. -- Link to post Share on other sites
dirkvdp 0 Posted February 23, 2014 Author Report Share Posted February 23, 2014 I checked some other sources, and to summarize briefly: the keys can be deleted - using programs as PsExec (http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx) - but are better left alone...

GT500 854 Posted February 25, 2014 Report Share Posted February 25, 2014 But I still think that true "portability" should imply leaving no registry traces behind (except for the normal MRU keys and the like). Unfortunately, Windows isn't designed that way. At least not when you have to use drivers to perform functions. If you do want to try deleting the registry keys, then I recommend first creating a new System Restore Point, and then creating a UBCD4Win disk just in case you need to restore the registry. You will need a Windows XP or Windows 2003 disk in order to build a UBCD4Win disk. Link to post Share on other sites
dirkvdp 0 Posted February 26, 2014 Author Report Share Posted February 26, 2014 I'm going to leave the LEGACY keys untouched. I know now that they do serve some purpose in Windows - there not just useless leftovers ("registry garbage"). quote Unfortunately, Windows isn't designed that way. At least not when you have to use drivers to perform functions. unquote Of course you're right - certainly when sys drivers are involved. But portable software makers can try to be as "clean" as possible. (That's why I appreciate so much what the people on http://portableapps.com/ and similar sites are doing.) To people who are more or less aware of what windows does "under the bonnet", having a clean registry, appdata folder and the like is not unimportant. As far as I'm concerned this thread can be closed now. Thanks for your reaction. It really helped to make sense of all this. -- Link to post Share on other sites
