Is it a good idea to defrag my PC before installing a new version of SW?
Would it help SW performance to run a defrag before installation?
Has anyone done so and seen an improvement in speed and/or less crashes?
If you're installing onto a conventional HDD then I'd suggest a defrag would do no harm. The gains would depend on its current level of fragmentation and in turn how scattered the installed data would be.
I'd probably run the defrag, at the very least it'll give you some time to do non-pc based tasks.
Change to SSD, improve speed and need not defrag at all.
I agree with Bjorn. If you have a solid state HD you will not see an appreciable difference after defrag'ing. Also, although Solid State hd's are very reliable, it is a good idea to not subject them to as many write/delete cycles as you can with regular HD's.
Along with the current defrag state, another consideration is the type of defrag you'll do.

It offers "quick" and a "regular". There can be a considerable difference in completion time, but the quick usually runs fast enough to make a worthy difference (relative to the time spent).
If you have the time to let it chug, like overnight, the regular method may be worth a shot.
If you're not keeping the previous SW version, you'll have holes after SW installs, so...
