Can I Delete Old Updates?

As time goes by, I get updates on different programs, which are stored on my computer and taking up space. Can I delete earlier versions as new ones are updated?

The answer to your question really depends on exactly which updates you’re talking about – as well as exactly how they’re delivered and installed.

Is Moore’s Law over?

My current computer is about 8 months old. It’s still being sold at Best Buy as new computer for about the same price. Also, many of the other models are about the same as mine. Nothing like this was around a decade ago. Is Moore’s law finished? Have we hit a barrier in new computers for speed? Or is it market forces that are simply responding to good enough computing?

Moore’s Law is often inaccurately quoted as saying that computer speeds double every set number of years. In reality, what Gordon Moore observed some years ago is that the number of transistors that can be packed on to a single chip was doubling roughly every two years.

Now I can’t tell you whether that still holds true. There are certainly physical limitations manufacturers must be encountering at some point, but some other interesting things have been happening as well.

What does NTLDR is missing mean?

I’m using Windows XP and I’ve gotten an error message, “NTLDR is missing. Do a Ctrl Alt Delete”. Please help! I’m going to change to Windows 7 but I need to get into my system.

NTLDR, more commonly referred to as “NT Loader” is the name of the file that contains the boot loader for Windows. In other words, it’s the program that begins the initial Windows booting process. Without it, you can’t boot.

What’s the Best Way to Upgrade from Windows XP to Windows 7?


Leo, I have a Windows XP computer with a lot of downloaded programs. I want to install Windows 7 on the computer since Microsoft keeps changing its operating systems and forcing you to upgrade (unlike Apple). How do I do this simply? A friend of mine told me to just get a Windows 7 disk and load it but I question that since I’ve read so many sites, which explain all kinds of convoluted operations. I’m not a computer expert.

If I use your recommended backup program, Macrium Reflect, will it back up everything – files, data, and programs or do I have to go back and download the programs all over again? I’m about ready to buy an Apple Mac since no one seems to have that problem with them. So again, how do I go to Windows 7 from Windows XP?

Upgrading from Windows XP to 7 has two basic approaches: the way you want it to work, and the way that’s more reliable. I’ll get to that, but first I want to explain why I disagree with your comments about Apple.
