During the last months Microsoft released several hotfixes to improve the startup time of Windows 7:

KB2510636 - An update that improves the startup performance of Windows 7 and of Windows Server 2008 R2 is available

Quote

Svchost.exe holds a lock on a service when the libraries for the service are loaded. This behavior prevents other services in the same Svchost.exe instance from starting until the call to the LoadLibrary function is returned.

KB2555428 - The Windows 7 startup process is slow when you create many restore points

Quote

Consider the following scenario:
You have a large hard disk installed a computer that is running Windows 7.
You create many restore points on the computer.
You try to start the computer.
In this scenario, the startup process may be very slow.

This issue occurs because the boot plan for the ReadyBoot feature exceeds the size limit of 512 kilobytes (KB). Each restore point creates a snapshot of Windows that Volsnap.sys must validate during the startup process. When you create many restore points, the boot plan for the ReadyBoot feature eventually exceeds the size limit of 512 KB, and cannot be stored. Therefore, startup I/O operations are not precached, and the startup process is slow.

Note The boot plan is stored in the following registry entry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\rdyboost\Parameters\BootPlan

KB2505454 - The startup process is delayed on a computer that has a large hard disk installed and is running Windows 7 or Windows Server 2008 R2

Quote

Assume that you install a large hard disk on a computer that is running Windows 7 or Windows Server 2008 R2. For example, the size of the hard disk is larger than 2 terabytes. In this situation, there is a short delay before Windows starts.

This issue occurs because the Microsoft Software Shadow Copy provider is being initialized.

So if you have one of those issues which slows down Windows boot, install the hotfixes.

New Hotfix:

Unexpectedly slow startup or logon process in Windows Server 2008 R2 or in Windows 7

Quote

When you perform one of the following operations on a computer that is running Windows Server 2008 R2 or Windows 7, the operation may take a long time to complete:

Start the computer
Log on to Windows

For example, the computer takes three or more minutes to start. This issue occurs because the Windows Management Instrumentation (WMI) component unnecessarily performs a full validation of the WMI repository.

Hi Magic Andre

Sorry to disturb you. Over the past few weeks I have applied these hotfixes in order to help with my boot speed. I just wondered if the hotfixes had any side effects? I can't be certain but I think one of these hotfixes has triggered this problem on my Windows 7 Ultimate (x64). Do you get this same odd behaviour & know how to fix it?

Basically I'll boot up my machine (alienware m17rx3) and then open ‘My Computer’. Then I’ll insert a USB stick or a dvd. Everything happens normally. However with ‘My Computer’ still open I will right click the USB stick and click eject & a message will always pop up. Most commonly ‘Explorer.exe – No disk’ ‘There is no disk in the drive. Please insert a disk into drive\Device\Harddisk1\DR1’. The box gives options to cancel, continue & re-try. If I click cancel the box will re-appear. Basically I have to click through it about 5 or 6 times before it eventually disappears. After that all is fine and dandy.

If I eject using the icon in the system tray I don't get the same problem. Likewise with a DVD, if I use the button on the top right of the laptop to eject the dvd the error message doesn't happen. It's only when ejecting using right click, eject on the drive within 'my computer'. I’ll get same message but instead of please insert to device\harddisk\DR1 it will say ‘Please insert a disk into drive D:’.

It’s also odd because it only does it once. Subsequent ejections of a dvd or USB stick are then fine. Until the next boot anyway. I have managed to stop / suppress the error by changing the errormode in the registry to 2. However it’s not a real fix & can suppress other error messages that I'd need to possibly see in the future.

As far as I can see there are no side effects, everything works absolutely fine but it does concern me. I have trawled google til I’m blue in the face with no joy. The common issue being that the USB stick has been assigned the C: letter and to change it in disk management but that doesn’t apply to me as it always gets assigned as E: whilst my DVD drive is D: I did try changing the drive letter for the sake of it but it didn’t help. Also tried disabling all start up items & clean booting with only MS services running – again no joy. Finally tried logging in with a new user profile and again no help. Other things I did was clear recent documents so nothing points towards either the optical or USB drives.

It’s getting kind of irritating. I am inclined to think hotfixes may of introduced this. But I can’t confirm this for certain as I don't know exactly when this started happening as I don’t normally eject this way. But now I have noticed the problem it is something I am keen to fix.

I did download process explorer to see if this gives a clue as to the cause but unfortunately I do not know what to look for.

Many Thanks,
Wayne

[MagicAndre1981]

remove all hotfixes and try if the issue is gone.

[Scottyboy99]

Ok thank you. I will try. Just worry risk of bricking the system by trying to back a hotfix out. Is it safe to do so?

Thanks,
Wayne

[MagicAndre1981]

sure, it is the same like uninstalling a normal update:

http://windows.micro...emove-an-update

[MagicAndre1981]

MS released a new Update which is called "Enterprise hotfix rollup" which also includes the Speedup fixes and many network related fixes.

An enterprise hotfix rollup is available for Windows 7 SP1 and Windows Server 2008 R2 SP1
http://support.micro...b/2775511/en-us


Download the Update from the update catalog (only works with Internet Explorer):

http://catalog.updat...spx?q=KB2775511

[vinifera]

wait this is for Enterprise SKU only or the patch collection is just named "enterprise" but work for all SKU's ?

[MagicAndre1981]

no, this update seems to work for all editions. It is only labeled Enterprise because it contains many network related hotfixes which are relevant in Enterprise environments.

To use this Web site's full functionality, you must be running Microsoft Internet Explorer 6.0 or later.

one would think after 10 years that this will stop being a problem

btw can anyone provide a normal installer link for this ?

I'd recommend you do not download hotfixes from any site other than Microsoft, there is no way to know what exactly you had tried to install.

[cluberti]

That error seems to indicate the publisher certificate is invalid - which would lead me to believe the package has been "manipulated" by whomever posted those "alternate" links. The Windows Catalog site requires an ActiveX control to work, hence it requires IE. Since you have Windows, you should have IE, and should be able to visit that site in IE, download/install the control, and get the hotfix.

[MagicAndre1981]

80073712 means WinSxS damaged.

[cluberti]

Indeed it can, although without the cbs log it's hard to tell which.

I removed it

[cluberti]

Well, that wasn't necessarily the best thing to do. Not sure what that buys you other than a feeling you made the box more secure (but didn't).

[vinifera]

there is a reason trust me and is securer

I'll try with portable version

[cluberti]

As someone who knows a bit about Windows Internals and how IE works on Windows (and IE internals), you should trust me that no, it doesn't. However, it's your machine, and you should do with it what you will - just know that no, it doesn't actually make the system more secure to remove IE.
