In space you can't scream!
TH2 purged CCleaner, but so far it seems like my other programs survived.
Only removed speccy here. CCleaner was left intact.
I realised that it had been purged (at least from the All Apps section) because I couldn't run it, despite having CCleaner Reg backups in my Documents folder.
The latest installer was in my Downloads folder, which is where I copy installers just prior to installing the software (i.e. I don't copy installers to W10 without running them).
No problems with CCleaner after the 10586.3 or 10586.11 th2 + cumulative updates here or the start up menu app folder and apps in there and pinned apps including my custom ones .
On one of the other PC's here during a 7x64 licenced upgrade to 10586.3 Speccy got removed and so did something else like that I cant remember .
I never could get Speccy to work in Windows 10 so I uninstalled it on this box a good while ago .
