I am trying to install Windows 10 but I get an message ‘Error—0xc0000269’ which says that I need to use a PC that has a compatible system to the operating system. I have a Hp Compaq computer with the AMD  440e dual core processor, 3GB RAM, 2.3 GHz processor and Windows 7 OS. The windows 8 version that I am attempting to install is 32 bit too. Is there any way that I can use to turn on the PAE? Is it that this processor does not support installation of Windows 10? What causes this situation? 

The system restore is not present in Windows 8.1 by default. Rather, it is an alias for system restore utility.exe. Is the system restore hidden too in windows 10 or it does not exist at all. I have tried accessing it to no avail. Help me

I'm currently on Windows 7 and I had installed Pinnacle Studio on my PC few days ago. It was working fine but I tried to uninstall it because of some compatibility issues. The uninstall icon on the Control Panel says that it cannot uninstall the studio. How can I completely remove the studio and get my PC not to load it?

I ran a virus scanner and it found some infections. I removed all the viruses as recommended by the antivirus. After the scan, I checked my C: along Windows folder. There's a strange folder named WinXS. What's that? It has some items which have meaningless name. For example, incrypt.dll, codename-911. What's the meaning?

I have an administrator account on my PC and I had changed it's password few days ago. For some days, I was out and now, I have forgot the password of my system. I'm currently running my PC from a 'Guest' account(which I always have). How can I recover the administrator password of my system?

I run my PC on Windows 7 and I often change the settings of my PC. 

' Do you want to change the settings?' click on OK.

' Do you want to change the settings?' click on Apply.

So, what is the difference between OK and Apply on any version of Windows though they have similar function?

Yesterday, as always, windows asked me to restart my pc to complete the installation of new updates. After this process was done, I restarted the system and noticed a watermark at the bottom of my screen. It was then that small pop-ups appeared saying that my system has not been properly activated or was fake. I have an original version of windows home premium which I activated online. Help?
