Windows 7

Remote Desktop mstsc.exe slow will not start windows 7

Had a painful problem today with the mstsc.exe application in Windows 7 64 Bit Ultimate today.


An otherwise happy install suddenly failing to start, or if is started it would be very slow.

Once started, it would not close from the task manager, even if I killed the process with the end process.


I suspected that it was possibly a virus etc. However I found that there are a lot of people on the net with this exact problem.

I then set about a solution, and figured on out myself, that involves replacing some of the files use by the MSTSC.EXE application.

Basically there are 4 files that I replaced with the same version from another computer that was functional and healthy. They are:








I would create a .zip copy for download except I fear giving out some stored connection settings in the files I already have. So sorry, you will have to find your own backup files.


The Bitch of it

The annoying problem is that you cannot just copy the 4 files into the two folder locations as Windows 7 in all it’s wisdom will not let you copy files there, as you are not the “Trusted Installer”.

You might be like me, Administrator and God of your computer that at any time can take to it with a hammer and replace it with a Mac, but Windows 7 knows best… so let’s show you what you have to do to hack that crap!


Give Permissions

First, go to the folder or set of files that you need to change permissions for, right-click on them and choose Properties.


Next click on the Security tab and then click on the Advanced button at the bottom:


Next click on the Owner tab and you’ll now see that the current owner is TrustedInstaller.


Now click on the Edit button and choose who you would like to change the owner to, either your account or the Administrators. If your account is an Administrator account, I would suggest just picking Administrators.


You can also check off Replace owner on sub containers and objects if you need to delete more than one file in a folder. Go ahead and click OK. Now you will see that the Current owner is the account you picked.


Click OK until you have closed all properties windows and are back to the Windows Explorer screen. Then right-click on the folder or file again and choose Properties again.

Now click on the Security tab again, but instead of clicking on Advanced, you need to click the Edit button.


Now click on the user name in the list that you want to change the permissions for, which should be the same as who you changed the current owner too. If the user name is not in the list, click Add, type in the name and click OK.


Since I had changed the current owner to Administrators, I clicked on Administrators here and then clicked on the check box next to Full Control. When you do that, all the other boxes get checked too.

Click OK once and then click OK one more time to get back to Windows Explorer. Now you can replace those files without any UAC messages telling you that you can’t! Enjoy!

Solution to – Windows 7 Slows with Thumbnail Previews of Images

Windows 7 Slow to Thumbnail Preview – Solution

We have found for the problem that we have experienced significantly with Windows 7. The problem is found when viewing in Thumbnail Preview a directory with a lot of image files in it.

Like you would a directory of icon images used in a graphic design company, or even a general user with a lot of images in your folder.

What happens is that the system stalls and chokes while a green progress bar slides from left to right taking anything up to 40 seconds to complete.


While the thumbnails are not displayed, but the default icon is in place while the computer has a good old think about that it will do next.

Strangely enough, this was something that worked well on the Microsoft Windows India (AKA Vista). Some how the US boys broke the thing when they took the code back from the Indians to pump out Vista (Rebranded Windows 7).

You can see where I am going with this… or at least can tell that I am completely fed up with the fact that massive computer system running a RAID Stripe with 3 of the fastest hard disks on the market, struggles to generate thumbnails from a file that the operating system has already created and hidden.

When my old iPhone 3 generates icons as fast as I can view them.

So that got me thinking how I can fix this.

Got me thinking back to solutions from Windows 95 days. There were thumbnail generating programs back then that worked faster than Windows 7.

Even had me thinking about breaking things apart into folders with less files in it.

But then it came to me….

The fix.

I am a proud mac owner. What the hell am I busting my hump trying to work out how to fix a problem that Microsoft created and never fixed since the release of Windows 7. I should stop thinking like a Windows Server Administrator and think like a user.

So User… what you going to do.

1. You already have Drop Box syncing the files since Microsoft Killed the pleasure you once had with Folder Share / Live Sync / (Some Busted Ass junk that no longer works since MS purchased Folder Share).

2. The directory is already on the mac, because Drop Box just works!

3. Just surf the images on the Mac.

What a pleasure. The experience was so good, that I just played with it fir 10 min or so, seeing how fast I could scroll and see if it could keep up. It could.

I went from this:

Solution found!  (I had to write this because it ticks me off so much that the basic features of Windows Still don’t work after soooo long!)

Thumbnail Generation is just one of many.
