Ok, I went ahead and upgraded to Windows 10. everything went smoothly, all my settings and installed apps preserved and work without a hitch. I am loving the interface and getting along with Cortana pretty good.
But after a while I encountered a weird issue: Appstore installed apps – e.g. Calendar, Mail etc. even Windows AppStore itself wouldn’t launch. I’d either get a cryptic error message, something along the lines “Application did not start, please contact system administrator” or very briefly a window would appear and immediately closed.
Looking into Event log was a bit more explanatory, but not too much: “Microsoft.WindowsStore_8wekyb3d8bbwe!App failed with error: Access is denied. See the Microsoft-Windows-TWinUI/Operational log for additional information.”
If you google it – you will find many possible explanations of the problem and many possible ways to solve it offered, but none of those worked for me. Finally I figured it out (and Event Log entry gave me a clue): C:\Program Files\WindowsApps folder was missing necessary permissions:
Namely, “ALL APPLICATION PACKAGES” was missing read & execute permissions on that folder (had to to uncheck “Hide protected operating system files” in Control Panel, File Explorer options to be able to see it). Once I added correct permissions – appstore apps started launching with no problems.
I spend ungodly amount of time trying to solve this issue, there were many similar issues reported on Lenovo forums, but no solutions and contacting Lenovo support is akin jumping thru hoops of fire.
The problem began after I plugged my brand new Thinkpad w540 into external monitor and set it to mode “Extended display (monitor + built-in screen). For a while everything worked fine, but then laptop own screen went black – and nothing could revive it. The external monitor worked fine and the maddening part was – when laptop booted – Lenovo logo appeared bright and shiny on laptop own screen, so I knew graphics card was OK. I ran full Lenovo System update, I updated NVidia drivers from Nvida site – nothing helped.
Then I tried to update Intel drivers for laptop’s HD Graphics 4600 card. Intel installer refused to install them because “The driver being installed is not validated for this computer“. To bypass that I
1. Unzipped the installer package into it’s own folder (you can use WinRar to unpack actual EXE or you can download Zip version of the package).
2. Went to Device Manager, right clicked on “HD Graphics 4600 card” driver and selected Update.
3. When prompted I selected “Browse my computer for driver software”
4. Selected “Let me pick from list of Device Drivers”
5. Clicked “Have disk” and browsed for an INF file inside of GRAPHICS folder of the unpacked driver files from Step 1
Installation commenced and lo and behold – laptop’s display sprang to life.
These instructions are specific to this laptop model and videocard, but I imagine they might be helpful in other similar situations. And hopefully Lenovo will take notice and finally update their drivers.

This will re-register MSXML and the error will go away.
If you have Windows 7 (or, God forbid, Vista) and trying to run games designed for older Windows version, you may experience 2 issues – game crashes on start and game starts, but displays weird colors. Classic example is “Worms Armageddon”.

A while back I wrote how my old Windows Vista (may she rest in peace) went into sleep mode while burning DVD-R. Well, it looks like much-bragged-about Windows 7 isn’t much better. During burning of 7Gb dual-layer DVD+R (using its own native burning app no less) it went into sleep mode. Argh! I see now how people become avid linuxoids. Is it time to switch to Ubuntu permanently yet?
