Is it possible to convert the system HDD MBR to GPT without losing information?

There is an MBR screw with Win10 installed. Is it possible to convert it to GPT without shamanism with the creation of a backup and other dances with tambourines? Are there images of flash drives "for the system administrator" with a set of programs that can work with disks?
And in general, does it make sense to do this, will it affect the speed of work? Windows on a relatively powerful computer loads ~ 5 minutes, and during operation it often happens that Task Manager shows a disk load of 50%
PS Do not talk about SSD, the computer is not mine, so the conditions are as they are.

Using GPT instead of MBR will not affect the speed in any way. You either have something actively eating up resources, or the HDD is slowly failing.

Yes, the same Akronis can do it on the fly, without losing information.
Therefore, if the information is not a pity - you can do it.
Backups are not required, they are made only when the information is valuable, and it cannot be lost.

And does it even make sense to do so?
Who knows what makes sense to you?
will it affect the speed of work?
Of course not! How magically partitioning can affect the speed of work ???

At least 8 GB of memory and an SSD will load quickly.
HDD is too slow for such tasks.
Do not talk about SSD, the computer is not mine, so the conditions are as they are.
Well, if the conditions are like that, then you need to learn how to benefit from slow work. For example, drink coffee, or read the news while it's loading.

There is an MBR screw with Win10 installed. Can it be converted to GPT
Yes, I know at least a couple of programs that do this without losing information - these are Paragon's HDM and AOMEI Partition Manager. In order not to bother with the search for their portable version for the sake of a one-time need, you can use any tool-recovery LiveDVD / LiveUSB containing the well-known utility package 2k10 - it has them. But it's better to get it from the very beginning - it will come in handy in a thousand cases later (I personally use MultiBoot ).
without shamanism with the creation of backups and other dances with tambourines?
It's still better to make a backup so that you don't bite your elbows later, especially for the sake of someone else's computer.
does it make sense to do this, will it affect the speed of work? Windows on a relatively powerful computer loads ~ 5 minutes ... Don't talk about SSD, it's not my computer
Still, I'll hint - on my computer (with an SSD on board, of course), the time from pressing the switch to the appearance of the Desktop is 20 seconds. So you just drop a hint about those 20 seconds to the owner, and that's none of your business.
And yet, in the context of what cannot be said : in the programs mentioned above, in addition to the ability to convert MBR<->GPT, there is also a special mode - "migration of the system partition to SSD".

It will not affect the speed in any way, there is no point in doing it.
Better check the disk smarts
