File Locker did not work for me (access denied), but Windows UI tool worked perfectly. It has less options, but it does a read lock, which is what I was looking for.

I am running Windows 7 x64 both as a host and a guest VM using VMWare Workstation v9. Here are the figures of Windows Experience Index for each instance, so you can estimate virtualization efficiency: Host Windows 7: Guest Windows 7 - VMWare Workstation v.9: Guest VM is allocated 2 cores, out of 4 cores total on my Intel i7-4770. As you probably have heard, Windows 7 uses logarithmic scale for its performance score.

Problem By experiment, I discovered that Visual Subst no longer works in Windows Server 2012, as good as it did in previous versions of the OS. Specifically for the purpose of referencing a DLL from a locally mapped drive. See below for more information. Assumption In Windows 2012, 32-bit and 64-bit processes use separate network drive mapping (later - Z:). Did not find a confirmation on the internet. Research 32-bit processes understand subst command, 64-bit need something else.

Firewall could not start because of error 1068 - some dependency failed to start. Outgoing connections work, incoming are blocked. I drilled down to Windows Firewall Authorization Driver malfunction.

Somehow my Windows 7 partially remapped a drive letter to another entity. It happened suddenly with some unexpected behavior. I noticed it when it could no longer connect to a network share. I removed the mapping and tried recreating with no success. The drive could not be deleted. Restarted, the drive is not mapped, yet it's still not available.

I got this 'Invalid class' error when querying disk performance data (Win32_PerfFormattedData_PerfDisk_LogicalDisk). The server was running Windows 2003 R2 Std x64 SP2.

For those who don't like to read stories, here's the extract Proceed with installation, even despite it appears to be a clean install. In the end you will get a working version, with all configuration preserved.

I recently upgraded to a larger hard drive and went from 1TB -> 2TB. Now the task was to make backup task in Acronis use the new location. I created new destination folder, moved all previous backups there. Then I changed Acronis backup task to do backups to the new place. Quite obvious so far, isn't it? Not with Acronis.

Some time ago I researched compression in various systems, ranging from software archivers (like WinRAR, WinZip etc.) to database solutions (like Oracle data compression). Then I figured there is one more type of compression that I did not touch yet - NTFS compression. People on the net say it's pretty much useless, still I decided to give it a try.

You happen to own an ATI video card, and updated to Catalyst 10.12. Now most likely you have this weird mouse lag in the top right corner of the screen. Some people report it appearing in other corners as well, both while gaming and staying on Windows desktop.
