Security Permissions Prob on XP SP3

I've just done a clean install of XP to SP3, after a HDD failure

Everything was going along swimmingly, until a short while ago

As part of the process, once I've got all Win updates onboard, I then move on to the Optimization of the System, using different tweak tools; I then compress the drives; I also use Partitions, which I've optimized using Easus Partition Master and do some Registry Cleaning and optimization, with a usually very safe and reliable tool; and once it's up & running safely, I use Doug Knox's Hotfix Backup Removal Utility

I'm not sure which of these caused the problem (perhaps Easus or TuneUp, both usually very reliable) but I now have no Drive Icons under Windows Explorer:

At first, I wasn't even shown 'Computer' and the drives under it! Just the Desktop and the folders there; and on my Start Menu, nothing I do will show my 'Computer' on the Start Menu

This has all kinds of follow on probs; Saving things via my Edited Places Bar means I can actually save things where I want, but if the Places bar isn't set to show during a save, I can't - it has to be the Desktop; This is only the least of the probs, but I think of it as the main marker for the effects of the problem. Cookies aren't working correctly; I can't give write permissions to some applications that need it on C:\, so they won't work correctly etc

At first, I thought this had to do with the Security 'Permissions' Properties; When the HDD failed, I needed to get something up and running in a hurry (My whole life's on the damn thing!) so went with my Christmas Present of Win 7, despite feeling it was too early for my liking; In my hurry -and due to a outbreak of general stupidity- I messed up the Security Permissions and found it a nightmare to sort out, once I'd calmed down, so much so, I went back to my old, trusty XP, on a different, new HDD

Despite that, I'm half convinced some ghost in the machine is carrying over some aspects of previous installations, something I've thought before; this isn't as daft as it sounds, since, one of the many benefits of Partitions\Multiple HDD's is Data security (Along with Quick Daily multiple Security Scans of the most vulnerable areas; quick, small, daily Image backups; Games can be easily re-used by just re-entering the serial, they don't usually need reinstalling; General Data Security etc etc); all I lost with the failed HDD was my OS Partition, my Program Files Partition and some Archives of DVD's, Games etc. The other partitions, such as Data, Games, Media, Backups were all re-utilized with Win7 (And Yah-Boo-Sucks to the 'Anti Partition Brotherhood'!) But I suspect I've caused another problem with the Security Permissions for C:\ on XP

I found a problem with the 'Creator\Owner' Security Permissions, so removed them and tried using my account name (which is Admin) on all Partitions, along with an Everyone LUA account, System, Administrator, Users, Authenticated Users, but I can't say I've ever completely understood these Permissions in their entirety

So, it's still not working right - and on other, preferred File Managers, it's even worse, as the Tree View doesn't even show the drives under Computer; and I can only get at the other Partitions via the Address Bar, previously setup Hot Keys etc, but it's not ideal and I'd like to sort the problem

I should also mention, I've an application that needs to write to My accounts' Local settings Folder, but that is stuck at 'Read Only' and I can't switch that off permanently, for some reason.....

So maybe, it's not the Security Permissions; I've removed all the backups for the Updates I applied, seemingly successfully, so can't undo them and see if that's the prob; the Reg Cleans I have as Backups, so can be re-merged with the Registry, but I've checked them and can see no reason for this; I've checked the other things I used and can see no reason for them to be the cause

Is this likely to be a Security Permissions problem? Can I solve this with a simple Registry Edit? Is this a known XP prob I just haven't come across before?

I should mention, I had Easus Partition Manager open and was about to hide my Dedicated Swap Partition, so it wouldn't show in Explorer etc, but coudn't remember whether this was a good idea or not (whether it invalidated the Swap Drive or not....?) So I had set it to 'Hidden' but then undid that and it seemed to be after that that I noticed the problem; but I wasn't convinced this caused the problem and nothing I can do with this tool seems to have the reverse affect or similar

All help much appreciated, so long as you don't tell me I need to do another clean install! (I HATE having to do that!)

Thank you
 
The next time you do a reinstall and apply the Windows updates, I strongly recommend stopping there. Tweak tools are tools of the devil.

Have you tried taking ownership of the files as opposed to just checking the individual permissions?
 
All your "optimisations" do seem a bit... psychotic. XP really isn't that bad that you have to butcher it. Makes finding the source or your problem much harder.

Should put Windows 7 back on. And stay away from permissions as evidently you and them don't mix! :p

Seriously, remove your optimisations as much as possible and see if the problem goes away.

Lol .... maybe a bit much, but a fellas' gotta have a hobby!

I've tried undoing most things, without effect, such as decompressing C:\ the optimizations etc

These are things I always use and always without a negative effect...mostly harmless, though obviously, somethings got the permissions messed up and I can't track it down

And yes, me & they don't mix, at all! I get a bit confused and it's not as though they're clearly explained..

I've tried taking ownership of the Drives -in the limited way you can with XP compared to Win7- (In particular C:\) but can't sort it and if I 'Replace Permissions on child objects...' all it does is mess things up more and I have to do things like remove\reinstall the graphics drivers etc

I'm resigning myself to having to do another clean install and maybe I won't be so manic when I do, but can't promise anything....

Thanks for the reply, chaps; All suggestions welcome!
