Windows 7 – Upgrading From Vista

Posted on May 16 2019 - 10:20pm by Rohit Shetty

For those still running Windows Vista and who may be interested in upgrading to Windows 7, I decided to document my experience of upgrading from Windows Vista Home Premium to Windows 7 Home Premium to provide a list of the things to watch for, what needs to be considered, an idea of how long the process will take, and a general feel for how it all works. Although in my case it was with the x64 (64-bit) Home Premium versions of Windows, the same should be true for the x86 (32-bit) versions.

The PC I did this on was built from new components in late 2009 and is an Intel Core i7 920 with 6GB DDR3 RAM, two linked CrossfireX graphics cards, 1TB SATA2 (C:) and 300GB SATA (D:) hard drive. Your mileage may vary in terms of the time the process takes for you.


Prior to inserting the Windows 7 DVD, I took a few steps to cover myself against unexpected complications. These involved the following:

My C: drive contains the operating system and programs only. All my data is on another drive, and I have important C: drive data backed up elsewhere.
Downloaded the Windows 7 version of my network card driver to my desktop.



Downloaded the Windows 7 version of my video card driver to my desktop.
Disable all third-party software that starts automatically.
Disable antivirus software, as the install program recommends.*
That was it, really.

Everyone says it, and I’m no different: backup any data that you cannot face losing before you start.

Note: I dual-boot between Windows and Wubi Ubuntu Linux, so that’s worth considering below when I mention Windows boot menus, It is likely that most Windows-only installations won’t show a menu most of the time, and it also shows that this process will work if you multi-boot your PC.

First Run — Compatibility Check

Upon inserting the DVD and running SETUP.EXE, I told it to install Windows 7 which, among other things, got it to run a compatibility check.

It flagged a number of devices and programs that “might not work after installing Windows 7”:

Device drivers: IDE storage controller and Canon USB scanner (ten years old now and only usable via VueScan’s generic scanner driver).
Programs: iTunes (reminded me to de-authorise it first), DaemonTools, and the ATI Catalyst software for my graphics cards.
The install software automatically removed the driver software, but this caused some issues for my SATA DVD-RW drive until I made a BIOS change (forced ACHI emulation instead of IDE), then I removed the programs as recommended.

Now for the install process, as I experienced it (time is shown in hours and minutes):

0:00: Step 1: Ran setup.exe on the Windows 7 upgrade DVD. Performed and passed compatibility checks, then started the installation proper (“copying Windows files”).
0:05: Step 2: Gathering information.
0:25: Step 3: Expanding Windows files.
0:30: System rebooted, Windows boot menu showed a “Windows 7 Installation” option which was automatically selected.
0:40: Continuation of file expansion.
0:50: Step 4: Installing features and updates, the screen flickered a few times (video drivers, etc).
0:53: Reboot. Same boot menu option automatically selected.
0:55: Step 5: Transferring files, settings and programs.
1:15: Reboot. Boot menu now showed “Windows 7” (rather than “Windows Vista”).
1:27: Reboot. Came up doing video performance checks. It made me enter my license key at this point,** and then began the post-install setup process (update installation schedule, clock, and time zone, network and firewall settings, etc).
1:32: The Windows 7 login screen appeared. Once I logged in with my existing username and password it followed by preparing the desktop, personal settings, etc.
1:38: Finally at the new Windows 7 desktop. Windows Update ran at this point and downloaded 65MB of updates. It included driver updates for my motherboard and peripherals (NIC, audio, video, etc) and I let it do all of them, figuring Microsoft had had so many problems with third-party driver updates over the years that they must have got it right by now. Sadly not.
1:46: When updates were all installed the machine wanted to be rebooted, so I did.
2:00: Upon coming back up I realized that my network connection was no longer working. Windows Update had got the NIC driver update (this is why I downloaded the Windows 7 version of the driver before starting the upgrade process). Ran the software to install the driver manually, and everything began working correctly. Did a manual installation of the video card drivers as well. This required another reboot.
2:25: All done.
The initial compatibility check run was first performed an hour before all this, so — including the preparatory work of downloading drivers and removing incompatible drivers and programs — the entire process took about 4 hours. It is fair to say that you should be able to do it in an evening, providing you have second-guessed Microsoft’s track record and you know what you are doing.


With the exception of the third-party driver updates screwing things up, it all worked perfectly well after a bunch of installations and 6 reboots. The rest of the work to be done was adding the removed software, re-enabling the software I wanted to automatically startup on boot, and general customization. Everything was running fine.

The final aesthetic changes I made are as follows, though you may prefer to skip these:

Disabled Aero Peek. I think it’s a resource-intensive gimmick, though I can see how others would like it.
“Unpinned” everything from the Taskbar.
Re-enabled the Quick Launch Bar.
It has now been a few months since I performed this upgrade, and I am still very pleased with it. It is a much more solid and usable platform than its predecessor.
