[Fixed] WinSCP resets PuTTY configuration

I did a little investigating:

The settings I use to call KittyPortable is :

z:\testing\KiTTYPortable\KiTTYPortable.exe !U@!@ -P !# -title "!N"

The steps I used for watching registry changes

RegFromApp - https://www.nirsoft.net/utils/reg_file_from_application.html
1. Open RegFromApp
2. Open WinSCPPortable
3. In RegFromApp, select File | Start with exisiting process & select WinSCPPortable
4. in WinSCPPortable, connect a server. Select Options | Preference | Integration | Application & change putty preferences. Select OK
5. RegFromApp detects no changes.
6. Exit WinSCPPortable and no changes detected

RegistryChangesView - https://www.nirsoft.net/utils/registry_changes_view.html
1. Open RegistryChangesView
2. Take snapshot
3. Open WinSCPPortable & connect & close
4. Take snapshot and compare. There are some references to WinSCPPPortable in the following keys
- HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search\JumplistData
- HKEY_LOCAL_MACHINE\System\ControlSet001\Services\bam\UserSettings\{%CSLID%}

5. Open WinSCPPortable, connect to server.
6. In RegistryChangesView, take new base snapshot.
7. In WinSCPPortable, update options (see above) and close
8. In RegistryChangesView, take new snapshot. Changes include
- HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store
- HKEY_LOCAL_MACHINE\System\ControlSet001\Services\bam\UserSettings\{%CSLID%}
As above, both of these key reference WinSCPPortable EXE file in "Value Name", and updated Value data of a REG_BINARY string

9. In WinSCPPortable, connect to server using Open Session from Putty (with KittyPortable settings)
10. In RegistryChangesView, take new snapshot. Changes include
- HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store
- HKEY_LOCAL_MACHINE\System\ControlSet001\Services\bam\UserSettings\{%CSLID%}

The last key now includes references with WinSCP.exe, PuttyPortableLauncher.exe, KittyPortable.exe,& kitty_portable.exe

In Regedit, both the Compatibility Assistant and bam\UserSettings\{%CSLID%} areas appear to contain a list of every file I've run (including numerous PortableApps). As far as I can tell, no specific Kitty data seems to be stored. The path/filename is, but this appears to be the norm form other PortableApps too.

Hope this helps
