I don't know if this should be a suggestion or a cry for help.
Patch MY PC will stall during the update of certain software like Skype or Chrome, and this is due to the updating application still running. Looking at the options the more reliable is to restart in safemode when running the maintenance. OR Have dSS run before the loading of user applications but just after loading of essential system services during startup.. This way user other than a cancel button the user has less chance of interfering with the maintenance cycle, and may help with some of the other maintenance items, not just the PMPC. I am all ears if others are using another application updater with better success (Please not Secunia)
IF you tell me we already have this ability.. I'll go and re-read foolishIT site from start to end as punishment (or education)..
The Second Suggestion is a Warning panel.. if the cleanmgr is selected to run and is run for the first time it can take a very long time worse on older machines -ie in service more than a year, and or large well used HDD's. Defraggler, again very fragmented, and large and well occupied Hdds - had a 500gb 20% used, 6% fragmented take 5 hours, similar story with a2cmd scan again with heavily used HDD's.. Is it considerable for a Warning to display, saying "This step if it is running for the first time, or if major changes have happened to your PC, May take considerable time to complete" - I was going to ask if a cancel this step button to appear after 5 or 10 minutes -but realised that with the range of 3rd party applications this would be too much of a write.
