Undeletable folders on Windows 7 after move (part of library)

By -

So the other day I was doing regular housekeeping on my Win 7 desktop, and I was moving stuff around, to make space for all these games I acquired from the steam sale. I move the “Movies” folder from drive G to drive S. The move completes, but there is still a Movies folder in my G drive.

I can’t open it. I can’t takeown it. I can’t icacls it. And I am an admin.

Turns out – that folder was referenced from a library (the videos library). I opened the video library, clicked on the (8 locations) link, and removed the G:\Movies from the list. Poof! the folder vanished.

Windows Task Manager is lying to you, and I don't know how to make it stop

If you use Windows, you might be intimately familiar with Windows Task Manager, which has a performance tab that shows the utilization percentage of various hardware in your system. Today, we're looking at CPU utilization. It looks a bit like this: The problem is that the meaning of the word utilization is very tricky. There can be multiple meanings: At the current time, with the current settings, what fraction of time is it executing instructions vs lying idle? At any time, with the most optimum settings, this CPU could practically complete a number a instructions at a certain rate. What percentage of that rate is it currently working at? I think the Windows Task Manager is currently using definition #1 above. This is useful for a person to look at the graph and understand "is there a runaway process on my system that is pegging my CPU"? However, consider the alternate use-cases: I am trying to run a long-running program, am I getting my money's worth out of this CPU...

Laptop Surprises: Lenovo Yoga Slim 7i

By -
I recently bought a Lenovo Yoga Slim 7i (Model 14ITL05). I really like it. I am trying to write down everything that surprised me about the laptop in here. These are mostly things that did not understand about the machine from the product page on Lenovo when ordering. I'll start off with the pleasant surprises: There is some sort of radar sensor on the top on the screen, in the webcam area. When I come and sit on my chair in front of the laptop, it wakes the screen and then Windows Hello logs me in with face ID. This is great! There is a feature called Battery Conservation Mode . What it does is: it pauses charging the battery when it reaches somewhere between 55 and 60%. So you can get the full performance out the CPU without adding a lot of wear on the battery. It allows the CPU to go to full performance with all the wattage coming from the AC adapter without worrying about battery wear. However, I would like to know more about this, and exactly why the battery percent...

Trouble installing KB2881553

By -
EDIT: The error is back :( These instructions did not help. EDIT 2: The error is mysteriously gone :) I think Microsoft did some magic on their end. I am back on automatic updates! For a long time, I was having trouble installing KB2881553: Update for the English Input Personalization Dictionary on Windows 8.1. These are rough notes on how I resolved it . The problem: KB2881553 is supposed to be only offered on machines that have a touch keyboard with lots of usage. I think it was offered on my desktop accidentally, because I also use a tablet PC with touch on the same Microsoft Account. If you hide the update, it doesn't go away, because a new version of the file is offered on Windows Update within a few days, on the same KB number. The error code was 6B2. The solution: I was mostly guided by this very helpful post . The gist of the problem is that the previous update .msi cannot be found, so you have to convince Microsoft that either (i) your package is up to...
