  1. If your recent test on a FEW RULES shows that a they are redundant, it neither proves nor disproves the value of other rules. Windows 7, and also presumable Vista, has BLACK HOLES where data disappears over the Event Horizon. All the rules are broken. Abandon hope all ye who enter ! ! ! I have just posted information on this problem at :- http://forum.piriform.com/index.php?showtopic=29618 Alan
  2. Please note that by default %LOCALAPPDATA% does NOT work on XP, even with SP3 I found this useful information, If anyone has a better source please update me. http://wapedia.mobi/en/Environment_variable?t=5.#5. I have a cleanup script for removing remnants of a specific application. It worked well on XP WIN 7 has crippled CMD.EXE with JUNCTIONS (reparse points) that partially support older software designed for XP. The command CACLS and the test "IF EXIST ..." tell lies or worse when routed via JUNCTIONS. I fixed all my problems by starting my script with IF "%LOCALAPPDA
  3. After DELETING a R.P. it is utterly pointless to retain previous R.P. Previous R.P will retain valid snapshots of the registry hives as they were, but the deleted files/folder data can NOT be reconstituted. CCleaner does NOT delete any R.P. - it merely purges the registry hives, so you still have a valid restoration chain of all files. Typically it will on my XP remove from an average R.P. a 55 MB registry snapshot, but leave a residue of 10 MB of modified/deleted files available for restoration. Alan
  4. Thank you Marmite Using Disk Management C:\ has free space = 8.67 GB and Capacity = 15.01 GB Windows explorer shows properties of 8.66 GB and 15.0 GB, and Used space 6.33 GB I am content that the discrepancy is merely that Management rounds up and Explorer rounds down. Using Windows Explorer if I select all files and folders contained by C:\, then the Size on Disc is significantly less 6.33 GB because my daughter's profile is not accessible to me, hence the quantity of files and folders and size on disc of her profile is excluded. That is why I logged out of my profile and asked
  5. First things I did when I got XP were :- Show Hidden Files and Folders ; Unhide extensions Unhide protected system files. C:\ is a 15 GB partition with 6.29 GB "Used Space" and 8.71 GB Free space When I select all the contents of C:\, properties shows me the "size on disc" To that I added the "Size on Disc" of my daughter's profile when she was logged on, and got close to 6.29 GB. I was content that with a bit of a struggle, Windows would show me all the files. One year later I discovered the existence of 168 MB of Metadata, and since Windows explorer was unable to show me any m
  6. marmite Sorry I distracted from original OP concerns. I accept your advice that Metadata is not wiped, and will now investigate what data is held in C:\$Extend\$UsnJnl:$J etc. which might be leaked when it is updated / fragmented. Thank you for the advice. Regards Alan
  7. I know that Perfect Disc excludes ten Metadata items from defraging, but I do not know if the exclusions are to avoid damaging the Operating System, or if it is to avoid wasting time trying to defrag items that are fully protected by the Operating System. The items I know of are :- C:\$MFT0::BITMAP C:\$MFT0Mirr C:\$LogFile C:\$Volume C:\$Bitmap C:\$Boot C:\$BadClus:$Bad C:\$Extend\$Quota C:\$Extend\$Reparse C:\$Extend\$UsnJnl:$J It shows that there are 387 excess fragments in C:\$Extend\$UsnJnl:$J and all the others have zero fragments. A separate table shows the sum total of A
  8. WHAT ABOUT METADATA ? Is there universal agreement or understanding of what Metadata is and does ? Do they all get wiped ? Do some or all escape wiping ? Do any that are not wiped have the potential to carry "private data" and leak when fragmented or upon next reboot ? Are the answers to the above dependant upon the O.S. and the tool used to wipe "free space" ? i.e. Mostly this topic has referred to various tools that run under Windows, but at least one referred to a DOS tool, and I am sure that Unix/Linux boot discs can also do powerful stuff ! ! On my system PerfectDisk
  9. Wireless Routers/Firewalls are vulnerable, especially if the Wireless link is not encrypted adequately. WEP is not adequate. Also WAP is not adequate according to http://blogs.techrepublic.com.com/security/?p=708 I use WAP2 so I have no fear - yet ! ! When WAP2 is broken then a neighbour MIGHT steal some of the bandwidth supplied by by ISP. I assume my hardware firewall "protects" my computer only from malware delivered by my ISP, and any wireless hack could enter my computer direct via the wireless without the hardware firewall being aware of it. This is yet another rea
  10. A Comodo software firewall protects me. Recently a Netgear Wireless Router / Modem was added. This gives a better connection speed than the Speedtouch modem I previously used. Netgear is set to allow "outgoing only", but I was amazed at the incoming it also allowed which should have been blocked. I have a dynamic IP address, so some days I inherit what was used by a more social animal, and the Comodo logs would show many incoming attempts from his Peer to Peer and Bit Torrent friends trying to resume yesterday's experiences. Far less often, I would get hit by a trojan army - pe
  11. I use Comodo Software Firewall, recently supplemented by Netgear Modem/Router/Firewall. The Netgear Modem gives better speed than the Thomson Speedtouch I previously used. Given perfect security, and freedom from errors by users, nothing nasty should come on-board. If any keyloggers get in, or if the P.C. is recruited into a BotNet army, software Firewalls give much better protection against "outgoing" than hardware firewalls. I like the fact that the hardware Firewall uses zero computer resources to block most of the attacks. BUT I have more confidence in Comodo. I have rea
  12. Hi I am sorry, my explanation was to concise. This has never happened before !!! I omitted to explain a stage I deliberately omitted from my recommendation. It is too late for Philip, but this may help others who see and act upon this thread. SYSTEM RESTORE IS NOT NEEDED - DO NOT WASTE TIME WITH IT !!! I suggested SYSTEM RESTORE at the point where you have broken the system, but if you are carefully checking only one extra option at a time, and running CCleaner with that extra option, if you test the system and determine it is not broken, then you can check and test th
  13. Hi I suggest being less ambitious !!! With a restored system that connects to the internet :- Run CCleaner with all 9 off Advanced settings unchecked, test Internet to make sure it is not broken by anything else; Mark one of the 9 check boxes in advanced settings, run CCleaner, test Internet etc. etc. Mark another check box in advanced settings, run CC and test internet etc. etc. and so on and so on. Finally, Internet will be broken and you now know what box killed it, and you can refrain from doing that one again, or you can come back for more specific advice - or just possibl
