That just means that the file is likely loaded upon boot so when you try to delete it, it's actually open and in use by the operating system.
No. It isn't.
absolutely NONE of this makes any sense. The file is 10MB. So freaking what? you aren't going to save any space at all by futzing about deleting "large" DLL files, which aren't even a tenth of a % of the total disk space.
use Programs And Features to remove Applications you don't use. Perhaps move your data to another drive. Whatever the case, people have been trying to "free space" by deleting random program DLLs strewn about their disk and all they get in the end is two fistfuls of their own hair. Use
WinDirStat to find out where your space is <actually> being consumed. You will find that a good chunk of it is in your own data folders. This is the same suggestion given days ago by Allan (treesize is the same type of program).
If that subdirectory will really get you a lot of space
94MB is not a lot of space.
Sometimes badly written install routines do not conform to the standards, and they install their application in a subdirectory not under program files. As long as it seems that the files in there are all related to the moviemaker application and you don't see other obvious program names or directories, you should be ok per my last post.
Movie maker doesn't have an uninstaller. It <IS> installed into program files, and deleting it will orphan about 40 file associations and COM component registrations. And yet this is how you propose they "clean up".
It sounds like you're system is in a bit of a death spiral.. I would 1st and foremost be totally sure you have all your data backed up because at this point, one of these times it just may not start up for you.
If it doesn't start up one day, I assure you it's because somebody gave them the idea it was ok to delete random DLL files.
Generally, because of how poorly windows cleans up after itself due to both windows and bad application deinstall routines, if you use your system heavily, especially if you install/deinstall programs somewhat often, it's just a good idea to re-core your system every couple of years, or more frequently.
Complete and utter nonsense. Especially considering "recore" isn't even a word any self-respecting tech would use.
As was posted earlier, if you're only running 2GB ram, your system is probably caching a good bit, and with the disk so full, if you don't regularly defrag, the caching will really bog down performance. To run windows with any decent performance, I never let the boot/caching disk get below 25GB free.
The pagefile is where data is swapped. It's not a cache. a cache is used to access data faster then it would otherwise be accessed, in this case since it's being stored on a slow medium (disk) rather then a fast one (RAM) it's not being "cached".
secondly, "cached" data is actually stored in low priority memory blocks by SuperFetch That is Cached data because it is being stored in RAM rather then on disk.
If you have not defragged, I would certainly try that, it alone may help the speed due to the above.
First:Defragmentation is not some magical panacea. You aren't going to see a computer go from "turtle slow" to blazing fast just because you moved a few clusters around on the disk. The fact that people actually believe to be the case this indicates that there is a lot of misunderstanding about what defragmentation actually does.
Second: Windows Vista & 7 automatically do some defragmentation during idle time. At least that what I suspect, considering I've had this install running for nearly a year and my fragmentation rate is 1% or less on all drives.
