Is Windows 8.1 an update for Windows 8 or an upgrade? In other words, is it a service pack or is it a new version of Windows?
Let’s find out.
Update: Bad link fixed
In computers, deleting a file is analogous to tossing a piece of paper into a trash can. Anyone could simply retrieve that piece of paper from the trash can; so could anyone undelete the file.
Proper data erasure, however, is possible; it is analogous to tossing a piece of paper into a shredder or burning it. Read the rest of this entry
VMware Workstation can import a Windows XP Mode virtual machine, enabling the owners of this product to have a VMware-compatible Windows XP within minutes. However, an imported copy of Windows XP Mode virtual machine will remain dependent on Windows XP Mode. This post will teach how to resolve this issue. Read the rest of this entry
I was using a Windows 7 Professional Edition machine to browse a network share on a Windows XP Home Edition netbook. The share contained two JPEG image files which I had put there. Seconds after browsing the network share, a
thumbs.db file appeared beside the two image file.
Like all badly-written error messages, it did not make any sense. I was not trying to open any file; I was trying to open Photoshop itself. I was sure that none of the Photoshop’s files were changed. (A look on the access date of the files confirmed this.) Moreover, I was sure that even if Photoshop was somehow automatically updated, the file system access permissions were not changed. (AccessEnum tool confirmed this.) So, what was the problem? Read the rest of this entry
Finally I feel safe to share this trick: Adding a “Run As…” command to .MSI files and .MSP files in Windows XP and Windows Server 2003.
In my earlier post, I discussed Run As… command which makes using limited user accounts more convenient. However, if you right-click a file with .MSI or .MSP extension (Windows Installer) you will find no “Run As…” commands. So, you may encounter difficulties installing or patching using alternative credentials under a limited user account. In fact, you may know no other options but logging out and into another user account.
This post does not apply to Windows Vista and later, which use User Account Control in conjunction with Windows Installer service. Read the rest of this entry
There are cases of emergencies when a Windows system administrator wishes to know if system is started up or shutdown in a particular date or time. Fortunately, you can use the Event Viewer in Windows XP to determine the approximate time and date of startup and shutdown. Read the rest of this entry
Perhaps you know about Microsoft’s effective recommendation for safe computing: Always log in as a limited user account (LUA) and run program that require administrative privileges using Run As command in the context of another a user with administrative account. Windows Vista is the first operating system to put this philosophy into practice, making it default behavior. Read the rest of this entry
I did not know when exactly it began but annoying corrupt entries had appeared in my Windows XP autoplay dialog boxes, like the one in this picture. When the problem proved persistent and my standard maintenance tools failed to fix it, I decided to go for a manual fix.
Since there was no strong evidence about the source of the problem, all I had was assumptions and all I could do was investigating their validity. Read the rest of this entry
