Why, oh why! I can't select more then one file in the Vista Explorer - it's not important which view i select. And the order columns are missing in most of the views...

Next UAC takes like hours when I try to open OrcasBeta1VSTS_VPC_8PartsTotal.part01.exe - it is 700 MB of size, but why does UAC take that long? Looks like a bug to me!

It's driving me nuts!

I prefer 7-zip for compression/decompression. It can also handle rar and iso.

I'm  pretty sure it takes ages because winrar has to check for all connected archives to the one you're opening ..  The same thing on an xp machine, trying to open a large winrar compressed archive, cpu load is pretty much stays around 1-4%, extracting uses as much cpu as possible ... so its more to do with hard drive performance, the less read/writes to the disk the faster it will be at opening the archive up.

I have had that problem for a very long time (but i am stuck on RC2 here). The thing to do in this case (as I read on some obscure forum) is to do the Reset Folder thing in the Folder Options Dialog, View tab. Repeat this for every type of folder: Picture, Music (Album, Artist. etc), Videos, Documents, then restart your computer. This will fix the problem till it happens again, at an arbitrary point in time.

MS never fixes UI bugs. They prefer to call them "features". In very best cases they are providing some "workarounds".

I believe explorer checks every single executable before executing it (I think it searchs for a digital signature).

1.  What can be the No.1 annoyance? Removed toolbar buttons and gave me stupid "Burn" and "Organize" buttons. Give me back my Cut/Copy/Paste/Properties/Copy To/Move To/Up. But this is largely solved now due to an addon I found. QTTabBar. It's a .NET addon however so it slows down Explorer startup. It also has some other goodies to change the behavior of the misbehaving rude Vista Explorer.
2.  Has complete amnesia. Doesn't remember a thing. XP's Explorer has partial amnesia.
3.  Back button doesn't behave the same.
4.  'Apply to all folders' doesn't really apply to ALL folders. There's a registry tweak I found for fixing this.
5.  Broken breadcrumb in FTP.
6.  No simple search for non-indexed files. MS says that Vista's search searches both, indexed as well as non-indexed, but only the indexed search is fast. The non-indexed search is much much much slower than XP's non-indexed search, so it takes sometimes a lot of time to find a single file in the same folder. This issue is also now sort of resolved because I use Agent Ransack on Vista for non-indexed search. And there are plenty of search utilities.
7.  Some commands like "Open command window here" only appear when Shift is pressed. Also, it doesn't appear in the left pane.
8.  The preview pane is too slow for videos, sometimes photos too. Large videos absolutely start killing the CPU if the preview "pain" is enabled.
9.  Although copying and replacing is improved, there is too much to read in the dialog and the dialog is too large and occupies a large area of the screen. I'm not a baby to press 3 large buttons when a file conflict occurs. Because the description/explaination is so long, I've to read it many times if I don't remember the position of the button.
10. Cutting and pasting across drives leaves empty folders on the original drives. It should remove them when moving is complete. Definitely a bug.
11. It tries to select the entire row in all views, even in list and details view. So if you click on a white space beside a file, the file gets selected! This is a huge pain when selecting multiple files. Thankfully, they added a relief in the form of check boxes.
12. Applies the wrong template when there are mixed files.
13. Renaming files selects only the filename minus the extension (Resolved by QTTabBar!)
14. Sorts in reverse, that is, when clicked on any column, first sorts in descending order.
15. Auto-refresh/autosort/autoarrange. This is my most hated feature of Explorer and is absolute rudeness to the user according to me. Suppose I paste 5 files, they're all sorted by name and scattered across.
16. Does not show the "free space" remaining in the status bar on all folders unlike XP Explorer.

Not to mention the slow file operations which are reportedly "fixed" in SP1.

The problem here is quite subtle.

When you open an executable file, the process manager has to load the entire program out of memory before it can execute it, which for 700 megs can be a reasonable amount of time, but is still less than a second.

The problem now is that UAC needs to discover whether it should ask you for a permission hike. The best way is to scan that 700 MB for the manifest file. If this is near the beginning (i.e. is a vista file with embedded manifest) and this returns no, then we just set up the process and away we go.

If there is no manifest, we scan the entire file. This can take some time, but is still only in the region of 400ms per gig of executable. If we don't need to elevate permissions, then we can now set up our process nearly a second after we double clicked.

The real problem comes if we do need to elevate permissions.

Firstly there is no way to send user-level memory to administrator-level memory. This means we immediately dispose the 700 MB of user-level memory and set up a new process in administrator memory and reload the file. There's another second gone.

But wait, it gets worse. Because UAC is actually a second process, if too much time elapses between when it wants to start up and when it gets to the point where UI is available, any user interaction might force focus elsewhere - and this means that the UAC gets minimised.

Which means that for large executables with no embedded manifest which need elevation, you might end up waiting 3 seconds or more to see that anything at all is happening, and even when you do you might have accidentally minised the UAC dialog, and you'll then need to wait for the toolbar icon to appear before you can get on with your program.

To reiterate:

Small executables = very fast.
Executables with manifests and no elevation = very fast
Executables with manifests and elevation = slow
Executables with no manfiests and no elevation = fast
Executables with no manifests and elevation = very slow.


Btw, a good way of speeding up admin-needing apps with no manifest is to open a command window with admin permissions (small exe = fast) and then ask it to open the offending app, which gives it admin permissions by default, and can therefore just run the damn app. If you're making a big app (>100mb) that needs admin permissions and isn't an installer, split it in half, and get the first one to get admin permissions and immediately launch the second half.

I've just realized I've replyed to a eight month-old thread. Stop necrobumping!!

That is not true. The executable is memory mapped into the address space of the newly created process. It is then demand-loaded by page faults triggered in the virtual memory manager when the memory-mapped addresses are accessed. It is not loaded into memory in advance.

A lot of the delay in UAC is from the digital signature check it does.

But UAC's digital signature check requires running an algorithm over the entire file to hash check it, which requires the entire file be loaded into memory.

I also cannot tolerate Vista because of Explorer. Other things are tolerable, but Windows Explorer has changed so much, they should have given it a different name, that's what I think sometimes, it's not the same anymore. The experience I would call is RUDE. And because of Explorer, the whole UI of the OS changes, so the whole experience changes - Control Panel, (My) Computer, Recycle Bin, Network Connections, Network browsing. They've also spoilt Address Book and Add/Remove by making those 2 part of Explorer. Add/Remove although faster at populating apps than XP's Add/Remove is unbearable for me because of the new Explorer and it's ~!@#$ context-sensitive toolbar. Simply too many things are different.

UAC seems to take a while for large files. For instance, if I try to install Fear Combat, it takes about 5 minutes before I get a UAC popup. after double clicking the file.
