NVIDIA drivers consume 12GB disk space

Today I noticed a new optional package on Windows Update with the name NVIDIA driver update for NVIDIA Quadro NVS 150M and I made the mistake of installing it to my Windows 8.1 computer.

nvidia-update

When the message displayed that Windows started to download the 300MB installer I naively thought, that it is no problem, because Windows will use only the few-megabyte really useful files and drop the rest. On the contrary, a few minutes later I lost 12 GB free disk space from my C: drive. Losing 12 GB free disk space on an SSD drive is always frustrating, but when it is your last 12 GB, it is especially painful.

WinDirStat clearly showed that the C:\Windows\System32\DriverStore\FileRepository folder consumes the majority of my disk space. This folder contained a number of 300MB folder which name started with “nv”. I could peek into the driver store using DISM from the command line:

dism /online /get-drivers /format:table

But I prefer to use the free DriverStore Explorer from CodePlex which displays a nice GUI (this is my driver store after the cleanup):

driverstore-explorer

If there would have been only a single NVIDIA driver in this list I would have clicked the Delete Package button, but in my case this list contained at least 30 NVIDIA items. So which can I safely delete?

In Windows 8.1 the Disk Cleanup utility has an option to delete unneeded device driver packages, so I tried it:

driver-cleanup

Unfortunately it could reclaim exactly zero bytes disk space, which didn’t really help.

The Program and Windows window showed that I installed the 327.02 version from Windows Update, so I went to the NVIDIA Drivers Download page where I happily saw that a newer, 331.65 version is already available. Although this package is also over 200MB in size, the manual installation may give me more control.

After successfully downloading the latest version, I uninstalled the old one, and using the Next-Next-Finish installation wizard I installed the new driver. In this way I not only had the option to install nView or now, but by checking the Perform a clean installation checkbox I could clean up all the remaining parts of the previous version:

clean-install

The installation was quick and seamless, and I not only got my free disk space back, but I also have a more up-to-date driver (this is WHQL tested as well).

I think this was my last attempt to install an NVIDIA driver from Windows Update.

Launching Lync Web App instead of the Lync client

Sometimes happens that you receive a Lync meeting request, but when you click on the meeting URL the Lync client cannot join the external SIP domain. In these cases the simplest solution would be to launch the Lync Web App, however it won’t start in the browser if you have the Lync client installed.

The quick solution is to append ?sl=1 to the end of the meeting URL.

For example: https://FQDN/organizerID/meetingID?sl=1

You can read more about the internal launch logic of the Lync Web App: Launching Lync Web App.

I am not sure that this is a best practice to follow in 2013.

Run as Administrator on Windows 8.1

I use Windows 8.1 for four weeks now with a non-admin account of course. When I need admin privileges, I start the app with the well-known Run as Administrator option. I search for the app:

RunAs-1

Then comes the usual UAC dialog:

RunAs-2

Where I enter my user name and password:

RunAs-3

And when I hit Enter, nothing happens. Nothing. What? It worked for years, how can it be broken now?

I was angry about it, because this was the only issue in Windows 8.1 that made me upset on a daily basis. Then, after weeks, I suddenly realized that it was my fault: I didn’t read the instructions. Do you see now?

Note to self: RTFM!
