How to fix VirtualBox bidirectional clipboard without rebooting

This happens to me from time to time. Attempting to cut or copy text from within my VirtualBox guest (Windows XP) fails to work on my host's clipboard. The quick-and-dirty solution is to end the VBoxTray.exe process in the Windows guest's taskmgr (if your guest is *nix, you'll need to find the PID in 'ps' and kill it by PID), and then run VBoxTray again from the Guest Additions directory (for example, C:\Program Files\Oracle\VirtualBox Guest Additions) Came across this tip from the following VirtualBox bug ticket #6150 trail: https://www.virtualbox.org/ticket/6150

usoclient.exe in Windows 10 wakes up my PC with Wake Source: Unknown

Image
So for a few weeks now, I've been dismissing this new Windows 10 Creators Update nag dialog. Some days I wake up to find that my PC is already awake. It turns out that Microsoft's been doing something sneaky behind the scenes. I thought I'd done all the usual methods to prevent that scenario, such as disabling the mouse from being able to wake up Windows.  Looking in Event Viewer (eventvwr), I see the wake source is Unknown. We can run a command in Windows Powershell to list all Scheduled Tasks that could wake the PC: Windows PowerShell Copyright (C) 2015 Microsoft Corporation. All rights reserved.

How to block the Admiral anti ad-block detection message

Image
I don't mind seeing the occasional banner or text ad while browsing web sites. What I do mind is malvertising, auto-playing videos (despite steps taken by browsers to stop auto-play) and excessive ads that slow down my browser to the point where it affects the user experience. This is on a modern quad-core desktop PC with 16 GB of RAM.  To that end, I gave in and installed uBlock Origin a few years ago. If ads and third-party tracking hadn't gotten so bad, I would not have had to resort to an ad-blocker. These days, sites are fighting back. They're using ad-block detection scripts in order to request that you whitelist their site. In some cases, I am happy to do this. Recently, I've seen a new one with the logo "Powered by Admiral", which pops up a modal and asks you to whitelist.  These are usually on sites that have a ton of auto-play videos and Taboola ads ("Doctors hate this one weird trick!"). I get it. Sites need ad revenue to fund thei...

Diskpart - "The volume you have selected may not be extended" on Windows 2003 Server when enlarging boot disk (C:) in VMware ESX 3.5

This solution may apply to anyone trying to extend a primary boot volume in Windows 2003 Server (mine happened to be the R2 Enterprise edition, but may apply to prior versions of 2003 Server).  I was following VMware KB  1007266  to extend the boot volume on this Windows 2003 guest VM on ESXi (3.5).  This is a separate issue from the Microsoft KB # 841650 . Everything was fine when I attached the newly extended VMDK file to my helper VM.  But I kept getting the "The volume you have selected may not be extended" error and couldn't figure out why.  It turns out I didn't read the KB carefully enough.  Make sure you assign a drive letter in the Windows Disk Management UI first! Before assigning a drive letter: DISKPART> list disk   Disk ###  Status      Size     Free     Dyn  Gpt   --------  ----------  -------  -------  ---  ---   Disk 0 ...
